o Coppers, fixed and Copper sulfate (JD) - The lead discussed the uses and last NOSB sunset 

review of, and 2011 Technical Report on, fixed coppers and copper sulfate. The lead 

summarized additional language proposed for inclusion in the document, including language on 

human health concerns and environmental implications. The lead summarized copper sulfate 

public comments submitted during the last NOSB sunset review. The lead called for the 

consideration of adding a new work agenda item to discuss an annotation for copper sulfate, 

and for the addition of copper sulfate to the Research Priorities. Members discussed requesting 

an additional Technical Report for copper. Members discussed uses of copper sulfate and fixed 

copper products (including copper soap) in organic production and questions on environmental 

issues related to their use. Members will submit questions on copper to include in the request 

for a Technical Report to the lead.

o Micronutrients: Sulfates, carbonates, etc. (LP) - The lead discussed uses and international 

acceptance of, and recent annotation change to, micronutrients. The lead discussed 

environmental issues and has no specific questions for stakeholders. Members discussed the 

types of micronutrients commercially available, i.e., chelated micronutrients, in relation to the 

annotation restriction.

Discussion

• July 27 notes were accepted as written.

• Ammonia Extract (SE). The Subcommittee discussed the remainder of the proposal they did not vote 

on during the last call, specifically the definitions for ammonia. The lead motioned to rescind the 

previous vote (made on the July 27 call) in light of the new definitions, and the Subcommittee 

completed the votes. 

 The motion to classify ammonia extract as non-synthetic was completed at the July 27 call. 

Motion to remove the previous motion to add ammonia extract at 205.602 Nonsynthetic substances 

prohibited for use in organic crop production. 

Motion by: SE

Seconded by: WT

Yes: 6 No: 0 Abstain: 0 Absent: 2 Recuse: 0 

Motion to prohibit stripped Ammonia – created by separating, isolating and/or capturing ammonia or 

ammonium from an agricultural feedstock or other natural source using methods such as, but not 

limited to, steam stripping, pressurized air, heat, condensation, and/or distillation.

Motion by: SE

Seconded by: JD

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

Motion to prohibit concentrated ammonia – contains greater than 3% ammoniacal nitrogen and the 

total nitrogen content is predominately (i.e., >50%) in the ammonia or ammonium form.

Motion by: SE

Seconded by: ADB

Yes: 7 No: 1 Abstain: 0 Absent: 0 Recuse: 0 
Motion to add to 205.3(f): Nitrogen products with a C:N ratio of 3:1 or less, including those that are 

components of a blended fertilizer formulation, are limited to a cumulative total use of 20% of crop 

needs.

Motion by: SE

Seconded by: LP

Additional discussion: A member commented that he was not comfortable with the arbitrary 20% 

limit, although is supportive of the proposal at this time. 

Yes: 7 No: 1 Abstain: 0 Absent: 0 Recuse: 0 

• Lithothamnion (BC). The lead briefly summarized the proposal and the CS moved to a vote. 

Motion to classify lithothamnion as non-agricultural

Motion by: BC

Seconded by: ADB

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

Motion that lithothamnion does not meet the criteria for a wild crop and therefore cannot be certified 

to that standard.

Motion by: BC

Seconded by: SE

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

• Carbon Dioxide (LP). The lead summarized the petition requesting the addition of carbon dioxide to 

the National List and the Subcommittee moved to a vote. 

Motion to classify carbon dioxide as synthetic 

Motion by: LP

Seconded by: RG

Yes: 7 No: 0 Abstain: 0 Absent: 1 Recuse: 0 

Motion to add carbon dioxide at § 205.601

Motion by: LP

Seconded by: BC

Yes: 7 No: 0 Abstain: 0 Absent: 1 Recuse: 0 

• Biochar (WT). The lead summarized the draft document on cow manure derived biochar (CMDB) and 

gave a brief history of the listing of ash from manure burning. The petitioner is seeking to add an 

annotation/exemption to the listing of ash from manure burning, which is listed at § 205.602 and 

prohibited for use. Members discussed the production of nitrogen and ammonia from the production 

of CMDB, noting that it is minimal. The group also discussed the addition of the definition of cow 

manure derived biochar. The lead will make some minor modifications to the document and 

recirculate. The CS proceeded to a vote based on the verbal acknowledgement of the edits to be 

made. 

Motion to classify cow manure derived biochar (CMDB) as non-synthetic.

Motion by: WT

Seconded by: RG

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 
Motion to annotate the listing of ash for manure burning at § 205.602 to read: “Ash from 

manure burning – unless derived as part of the production of biochar from pyrolysis of cow manure.”

Motion by: WT

Seconded by: SE 

Yes: 5 No: 3 Abstain: 0 Absent: 0 Recuse: 0 

• Additional Items. 

• The meeting was adjourned

Agenda

• Review July 20 notes

• Ammonia Extract (SE) - Discuss proposal

• 2023 Sunset: Magnesium oxide (ADB) - TR sufficiency, Discuss review/vote

• Lithothamnion (BC) - Discuss proposal/vote

• Sodium Nitrate (SE) - Discuss proposal/vote

• Hydronium (RG) - Discuss proposal/vote

• Additional Items

• Adjourn

Discussion

• July 20 notes were approved as written

• Ammonia extract (SE). The lead summarized the draft proposal for ammonia extract and also 

discussed the sodium nitrate listing in the context of nitrate use in organic agriculture. Members 

discussed the broader topic of nitrogen use, the potential for fraud, and the ability for certifiers to test

for nitrogen levels. A member also mentioned input of nitrogen in hydroponic systems. The 

conversation also included discussion of the 20% cap for sodium nitrate and what that percentage was 

based on. The CS moved to a vote on two of the motions and will vote on the definition on the next 

call. 

Motion to classify ammonia extract as non-synthetic. 

Motion by: SE

Seconded by: JD

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

Motion to add ammonia extract at 205.602 Nonsynthetic substances prohibited for use in organic 

crop production.

Motion by: SE

Seconded by: RG

Yes: 7 No: 1 Abstain: 0 Absent: Recuse: 0 

• 2023 Sunset: Magnesium oxide (ADB). The CS found the TR sufficient and the Chair will send an email 

to the NOP to confirm. The lead summarized the uses of magnesium oxide and noted that the TR did 

not identify any detrimental environmental effects. The Subcommittee moved to a vote. 

Motion to remove magnesium oxide from the NL

Motion by: ADB
Seconded by: LP

Yes: 0 No: 8 Abstain: 0 Absent: 0 Recuse: 0 

• Lithothamnion (BC). The lead discussed the process he used to determine the classification for 

lithothamnion. Based on the materials classification decision trees (NOP 5033, NOP 5033-2) and the 

guidance on wild crops (NOP-5022) the Subcommittee determined that lithothamnion is nonagricultural and therefore cannot be certified to the wild crop standard. This determination also aligns 

with what a previous Board recommended. The NOP suggested changes to the wording of the motions 

to separate the classification motion from the NL motion and the Subcommittee will vote on the next 

call. 

• Sodium Nitrate (SE). The lead summarized the history of the sodium nitrate listing, noting that it is 

non-synthetic and was listed at 205.602, prohibited for use, with an annotation to allow for up to 20%. 

In 2012 the NOSB voted to remove the annotation and prohibit its use altogether. The NOP did not 

complete rulemaking, and therefore sodium nitrate “sunsetted” but was not removed from the list

(based on the previous sunset process) and therefore is considered an invalid listing. The NOSB 

submitted a proposal for the Fall 2021 meeting to relist sodium nitrate at 205.602 with annotation. 

Motion to reinstate sodium nitrate at 205.602 with the following annotation: Sodium nitrate – unless 

use is restricted to no more than 20 percent of the crop’s total nitrogen requirement; use in spirulina 

production is unrestricted until October 21, 2005.

Motion by: SE

Seconded by: BC

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

• Hydronium (RG). The lead summarized the uses of hydronium, noting that the petitioner has also 

submitted it to EPA as a biocide, and its registration is pending. The NOSB typically does not list 

substances without EPA registration. The CS moved to a vote.

Motion to classify hydronium as synthetic 

Motion by: RG

Seconded by: ADB

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0 

Motion to add hydronium at 205.601(j)(7) as an organic processing aid

Motion by: RG

Seconded by: SE

Yes: 0 No: 8 Abstain: 0 Absent: 0 Recuse: 0 

• Additional Items. None. 

• The meeting was adjourned

Discussion

• July 6 notes were accepted as written. 

• 2023 Sunset: Copper sulfate (JD). The lead summarized the public comment and feedback from 

various stakeholder groups from the Spring 2021 meeting. Two stakeholders voiced opposition to use 

of copper sulfate and advocated for continuous improvement. The CS will add a research priority (RP) 

on alternatives to copper and send that to the MS lead for incorporation into the Fall RPs. 

Motion to remove copper sulfate from the NL at 205.601(a)(3) and 205.601(e)(4)

Motion by: JD

Seconded by: RG

Yes: 2 No: 6 Abstain: 0 Absent: 0 Recuse: 0

• 2023 Sunset: Peracetic acid (WT). The lead summarized the substance and noted there is wide support 

from the community for relisting. 

Motion to remove peracetic acid from the NL

Motion by: WT

Seconded by: JD

Yes: 0 No: 8 Abstain: 0 Absent: 0 Recuse: 0 

• 2023 Sunset: Chlorine materials (WT). The lead introduced the uses for chlorine materials and made 

the distinction between them and peracetic acid, which is relatively benign. Both substances are 

essential for meeting food safety requirements although some members voiced concerns about the 

use of chlorine materials on produce. 
Motion to remove chlorine materials from the NL

Motion by: WT

Seconded by: LP

Yes: 0 No: 8 Abstain: 0 Absent: 0 Recuse: 0

• 2023 Sunset: Calcium chloride (LP). The lead summarized the uses of calcium chloride, particularly as a 

foliar spray on crops, and noted that it is an important product for growers. The CS is supportive of 

relisting and moved to a vote. 

Motion to remove calcium chloride from the NL

Motion by: LP

Seconded by: BC

Yes: 0 No: 8 Abstain: 0 Absent: 0 Recuse: 0

• 2023 Sunset: Ozone gas (RG). The CS recently received the TR for ozone and the CS found it sufficient. 

The Chair will send an email to the NOP confirming that. The lead felt that the information in the TR 

would not change the tenor of the proposal, and the Subcommittee would not need to revote. The 

lead will add citations from the TR to the document, and will submit the document to the NOP for 

posting for the fall meeting

• Kasugamycin (RG). The lead summarized the uses of kasugamycin, and the members discussed 

antibiotic use in agriculture, antibiotic resistance, and potential detrimental soil effects. It was noted 

that most stakeholders, with the exception of some fruit tree growers, are not supportive of antibiotics 

being on the National List. A member mentioned that there are alternatives for fire blight, although 

they may be difficult to use and may not be as effective in certain climates and regions. The group 

feels that kasugamycin does not meet the OFPA criteria for compatibility with a system of sustainable 

agriculture, and moved to a vote.

• Hydronium (RG). Hydronium is classified as synthetic and is being petitioned for use in manure to 

control odor control and lower pH. The petitioners have also submitted a petition to the EPA to classify 

hydronium as a biopesticide, but it has not been approved yet. The lead will write a proposal and the 

CS will complete its review and vote on the August 3 call.

• Biodegradable Biobased mulch film (BBMF) annotation change (AB). The lead summarized the draft 

document, pointing out modifications that were made since the last meeting. He noted support from a 

wide array of organic organizations. Members discussed the potential use of BBMF and whether it 

would displace the use of polyethylene films (PE). A member suggested the inclusion of restrictions for 

non-continuous use, which the lead will incorporate into the document. The CS moved to a vote based 

on the proposed changes.

Discussion

• June 15 notes were accepted as written.

2023 Sunset: Copper sulfate (JD). The lead summarized both listings for copper sulfate, including uses 

and international standards. Public comments at the Spring meeting were mixed. Rice growers were 

supportive of listing, and those commenters opposed cited possible accumulation of copper in the soil 

and lack of continuous improvement. The group discussed both the positive environmental benefits 

and identified negative impacts to aquatic species. The group also discussed specific application rates

and its impact on soil. The CS recommends re-listing copper sulfate but emphasized the need identify a 

better solution such as cultural practices, alternative materials, or a combination of both. The CS 

deferred the vote to the next call. 

• Research Priorities (ALL). The Crops Subcommittee will add a research priority on copper. JD will 

forward to the CS Chair for incorporation in the document that they will then send to the Materials 

Subcommittee.

Ammonia Extract (SE). The lead summarized the petitioned uses of ammonia extract, noting public 

comments from the Spring meeting. To help inform the proposal, the lead has engaged with 

stakeholders including the Organic Trade Association’s ammonia extracts task force. The CS discussed 

the OFPA criteria for compatibility with a system of sustainable agriculture, a holistic systems 

approach, and alternatives, including crop rotation. The lead will complete the proposal and the CS will 

vote on a future call.

• Lithothamnion (BC). The Board received a memo from the NOP asking them to determine 

classification of lithothamnion and if it can be certified to the wild-crop standard. The group discussed 

the synthetic vs. non synthetic decision tree for and based on the conversation, the lead will modify 

the document and discuss it on the next call. The group also discussed whether to develop a discussion 

document or proposal, and decided to write a proposal, and also pose questions for public comment 

regarding definitions in the wild crop standard. The vote was deferred. 
• Biodegradable Biobased mulch annotation change. Members discussed how to move forward with 

the proposal. The lead noted that the crux of the proposal relies on a comparative risk assessment:

using a petroleum based product that must be removed from the land each year and ends up in a 

landfill, versus one that is not 100% biobased at the moment, but biodegrades into the soil. A member 

asked about cumulative effects, from using the mulch film every year versus intermittently. Members 

acknowledged the fact that there are currently no products on the market that would meet the 

standard, which is aspirational, and discussed how to incentivize the industry to move towards the

ideal of 100%. The lead will modify the current draft based on public comment from the Spring 

meeting and today’s conversation and the CS will vote on a proposal on a future call for the Fall 

meeting. 

• Carbon Dioxide (LP). The lead summarized the current draft document. The CS did not request a TR, as 

they felt that they had enough information to move forward. The group discussed whether to bring a 

petition discussion document or a proposal to the Fall meeting and chose to write a proposal with 

questions to solicit community feedback. The CS will vote during the August 3 call.

• Additional Items. None.

• The meeting was adjourned.

Crops Subcommittee (CS) Notes

Tuesday, June 15, 2021 2:00 pm ET

Present: Rick Greenwood (RG), Chair; Jerry D’Amore (JD); Amy Bruch (ADB); Wood Turner (WT); Logan Petrey 

(LP); Asa Bradman (AB)

Absent: Steve Ela (SE), Vice Chair; Brian Caldwell (BC)

Staff: Michelle Arsenault (MA); Jared Clark (JC)

Agenda

• Review June 1 notes

• Carbon Dioxide (LP) - Discuss proposal/vote

• 2023 Sunset: Ozone gas (RG) - Discuss review/vote

• Sodium Nitrate (RG) - Request to add to work agenda 

• Additional Items

• Adjourn

Discussion

• June 1 notes were accepted as written

• Carbon Dioxide (LP). The lead summarized the petitioned use for carbon dioxide to lower pH levels in 

irrigation water. She noted questions about the release of CO2 and its potential effect on climate 

change, as well as environmental benefits for carbon capture. The CS also discussed alternatives used 

in organic production such as sulfur “burners” and citric acid. Initial feedback from a stakeholder was 

that transitioning from sulfur burners is expensive, and the CS is interested in hearing from other 

stakeholders about alternatives. The CS did not request a TR as they felt all the questions were 

answered in the petition and could be gleaned from public comment. The CS will put forth a discussion

document rather than a proposal at the Fall 2021 meeting in order to solicit more feedback. The lead 

will complete the document and the CS will discuss and vote on the next call. 

• 2023 Sunset: Ozone gas (RG). The lead summarized the uses of ozone in organic agriculture. There are 

no environmental concerns with the breakdown products, it’s in wide use, and public commenters

were nearly unanimous in favor of re-listing.

Motion to remove ozone from the National List

Motion by: RG

Seconded by: ADB 

Yes: 0 No: 6 Abstain: 0 Absent: 2 Recuse: 0 

• Sodium Nitrate (RG) - Request to add to work agenda. The group discussed the request for a work 

agenda item to add sodium nitrate to the National List again, where it was previously listed at 205.602. 

The 2012 NOSB recommendation was not implemented, and therefore the sodium nitrate listing is 

considered invalid, but was never removed from the list. The CS will send the request to the Executive

team, who will meet later today. The group also discussed the relationship between ammonia extract, 

which was petitioned for addition and is currently under review, and sodium nitrate, specifically

solubility. Several members highlighted the broader issue of nitrogen use in agriculture and the use of 

imported nitrogen versus cover crops and crop rotation. 
• Additional Items. None.

• The meeting was adjourned.

• 2023 Sunset: Rotenone (RG) - Discuss review/vote

• Additional Items

• Adjourn

Discussion

• May 18 notes were accepted as written.

• 2024 Sunsets - TR requests. The CS determined the need for TRs for the 2024 sunsets and only 

requested one limited scope TR for polyoxin D zinc salt.

• Chitosan - plant disease control (RG). The lead summarized the draft review, noting that chitosan is 

synthetic and considered a benign compound derived from shellfish. It is being petitioned for use for 

broad-spectrum plant disease control. The lead noted that there are over 200 compounds already 

listed in the Organic Materials Review Institute (OMRI) Database for the same use that are nonsynthetic. The group discussed efficacy and alternatives, including chitosan as an alternative for other 

substances such as sulfur. A member asked about information in the petition indicating that chitosan 

could be used as a plant growth regulator. The Subcommittee moved to a vote, which was divided.

• Chitosan - coagulant for fertilizer (RG). The lead summarized the substance, which is being petitioned 

as a value-added product. The CS sent follow-up questions to the petitioner in September 2020 and 

got no response. Without responses to its questions, the CS deemed the petition insufficient at this 

time and will send the it back without review. The NOP will transmit the information to the petitioner. 
• 2023 Sunset: EPA List 3 - Inerts of unknown toxicity (SE/AB). The lead summarized the draft review 

and noted that for now, without a better process in place for inerts, they should be relisted as they do 

not have contact with crops, and it would be disruptive to growers. He added that the list 3 inerts will 

likely be considered as part of the work the NOP is undertaking on EPA List 4 inerts. The group 

discussed some additional language to add to the review and moved to a vote. 

Motion to remove EPA List 3 - Inerts of unknown toxicity at § 205.601(m)(2)

continue its prohibition.

Agenda

• Review February 16 notes

• Hydronium (RG) - Discuss need for TR

• Carbon Dioxide petition (LP) - Petition sufficiency/Determine need for TR

• Ammonia Extract (SE) - TR sufficiency

• Additional Items

• Adjourn

Discussion

• February 16 notes were accepted as written

• Hydronium (RG). The group re-reviewed the petition, and although a previous iteration of the Crops 

Subcommittee had deemed it sufficient and requested a TR, the current Crops Subcommittee revisited

the need for a TR, and determined that one is not needed. 

• Carbon Dioxide petition (LP). The lead summarized the petitioned uses of carbon dioxide and the 

Subcommittee found the petition sufficient. The group discussed the scale of use and potential 

environmental concerns with producing carbon dioxide, which would not be released to the air. A 

member recommended that when reviewing this substance, the group consider only the petitioned 

use and not an expanded use. The NOP pointed out a previous TR for CO2 (in Handling), and suggested 

that it may contain enough information to complete the review, and if not, the CS could request a 

limited scope TR. 

• Ammonia Extract petitioned (SE). The lead summarized the answers to the questions the 

Subcommittee posed to the TR contractor, and the group discussed them, as well as alternatives and 

the potential for fraud. The CS felt that some of the information in the TR about impacts on soil was 

not detailed enough, but acknowledged that there may not be a way to glean the information via 

another addendum to the TR. The CS found the TR sufficient and will reach out to stakeholders to 

supplement the information. 

• Additional Items. 

o NOP spoke with the petitioner for chitosan (as a flocculant) and the petitioner will submit an 

addendum with answers to the additional questions from the Subcommittee. 

o The Crops Subcommittee canceled the March 16 call

• The meeting was adjourned.

• Additional Items

• Adjourn

Discussion

• February 2 notes accepted as written

• Biodegradable Biobased mulch film (BBMF) annotation change proposal (AB). The lead summarized 

the draft proposal as well as the history of the project thus far. Initially when the NOSB recommended 

BBMF, the presumption was that it was 100% biobased, and it was later discovered there are no 

products that qualify. A subsequent NOP memo clarifying this was later withdrawn and the NOSB is 

reviewing the listing again. The group discussed of impacts on soil health, and breakdown products, 

and a comparative risk assessment between polyethylene film and its manufacture compared to 

biodegradable biobased mulch film. The group also discussed a requirement for a certain percentage 

of biobased content. A member added that if/when the film is tilled into the soil, it would be several 

inches below the surface where there are active microbes, and therefore it would not be broken down.

Motion to accept the proposal on the biodegradable biobased mulch annotation change (with 

proposed additions to the definition at 205.2)

Motion by: AB

Discussion

• January 19 notes accepted as written.

• Kasugamycin (RG). The lead summarized the petitioned uses for kasugamycin and noted that it is an 

antibiotic, although it is not used in humans. The draft summary includes manufacturing information, 

environmental concerns about cross resistance, and potential soil contamination. A member noted 

that kasugamycin resistance in conventional ag is already present. The TR was found sufficient and the 

CS voted on the discussion document and will submit it for public feedback at the Spring meeting. 

Motion to accept the discussion document on kasugamycin

Motion by: RG

Seconded by: SE

Yes: 8 No: 0 Abstain: 0 Absent: 0 Recuse: 0

• 2023 Sunset: Chlorine materials (WT). The lead summarized the draft review, noting the four 

substances listed under chlorine materials. Both the Handling and Livestock Subcommittees are also 

reviewing chlorine materials. The Food Safety Modernization Act (FSMA) is a consideration for the 

handling listing, but not necessarily Crops. Members expressed concern about widespread use of these 

materials and potential human health and environmental issues, while also acknowledging the 

difficulty in removing them from the list due to the lack of alternatives and FSMA requirements. The 

HS will add questions to the review that emanated from the Fall 2020 Sanitizer panel. The Crops Chair 

mentioned that the TR for ozone discusses some of the concerns discussed here. 

• Biodegradable biobased mulch film (BBMF) annotation change (AB). The lead discussed the issues 

the NOSB has been grappling with over the last few years with regard to BBMF. The listing requires 

100% biobased material, and there are currently no products that meet that standard. The question is 

whether to maintain the listing as is, and make it aspirational, or to modify the annotation to allow for 

BBMF with a lesser percentage, which means it would contain a certain proportion of petroleum based 

products. The CS noted that they are aiming for consistency with paper pots. 

• Carbon Dioxide petition. LP volunteered to lead the review for carbon dioxide.

• The meeting was adjourned.

Discussion

• January 5 notes were accepted as written.

• Research Priorities. The Crops Subcommittee Chair will reach out to the former Chair to see if there 

are other items from the last round of public comments that should be included on the research 

priorities list, and then send the finalized list to the Materials Subcommittee.

• 2023 Sunset: EPA List 3 - Inerts of unknown toxicity (AB/SE). The lead will add additional questions to 

the draft review and submit the document for the Spring posting. 

• 2023 Sunset: Copper sulfate 205.601(a)(3) & 205.601(e)(4) (JD). The lead summarized the uses of 

copper sulfate and possible environmental health concerns. Based on feedback from stakeholders

about alternatives, the lead added a couple of questions regarding dry seeding. A member also 

identified sodium carbonate peroxyhydrate as an alternative, and noted that both substances are 

typically used simultaneously. The lead will forward the document to the NOP for posting to the web 

for the Spring meeting. 

• 2023 Sunset: Ozone gas (RG). The lead summarized the uses of ozone gas in organic agriculture, and 

noted that although it is a strong oxidizer, it doesn’t have residue, so it is considered to be relatively 

benign. Human health concerns are minimal because it’s used in a closed system. The lead will forward 

the review to the NOP for posting. 

• Paper based crop planting aids (SE). The lead summarized the previous iterations of the document 

and subsequent feedback from public comment. The group discussed the additions and moved to 

three votes on paper pots: 

Motion to classify paper based crop planting aids as synthetic 

Motion by: SE

Seconded by: JD 

Yes: 6 No: 0 Abstain: 0 Absent: 1 Recuse: 0
Motion to add to 205.2 Terms Defined:

Paper-based crop planting aid. A material that is comprised of at least 60% cellulose-based fiber by 

weight, including, but not limited to, pots, seed tape, and collars that are placed in or on the soil and 

later incorporated into the soil, excluding biodegradable mulch film. Up to 40% of the ingredients can 

be non-synthetic, other permitted synthetic ingredients at §205.601(j), or synthetic strengthening 

fibers, adhesives, or resins. Contains no less than 80% biobased content as verified by a qualified third 

party assessment (e.g. laboratory test using ASTM D6866 or composition review by qualified 

personnel). Added nutrients must comply with §205.105, 205.203, and 205.206.

Motion by: SE

Seconded by: RG

Yes: 6 No: 0 Abstain: 0 Absent: 1 Recuse: 0

Motion to add to 205.601 (p) Production Aids:

• Biochar (EO/WT). The CS sent additional questions to TR contractor, and will defer this project to the 

Fall 2021 meeting. 

• Biodegradable Biobased mulch annotation change (AB). The discussion and vote were deferred to the 

February 2 call.

• Additional Items. 

o The CS deferred several projects to the Fall meeting, including chitosan, ammonia extract, 

hydronium, and biochar.

o A member asked that the Board continue to discuss containers at some future date. 

• The meeting was adjourned.

Agenda

• Review December 15 notes

Discussion

• December 15 notes were accepted as written. 

• 2023 Sunset: Peracetic acid 205.601(a)(6) 7 205.601(i)(8) (WT). The group discussed the sunset 

process in general, and summarized peracetic acid, emphasizing that it is a sanitizer. Peracetic acid has

been on the National List for a long time and is in wide use. A member noted that since the Food 

Safety Modernization Act (FSMA) was passed, it has become more important as it is an alternative to 

chlorine materials. 

• Research Priorities. The group discussed the Fall 2020 research priorities list and will assess if they 

should make additions, changes, or deletions. The MS Chair will reach out to the previous MS Chair to 

see if there was any additional feedback from the Fall 2020 meeting. 

• Kasugamycin petition (RG). The lead summarized the petitioned uses of kasugamycin and members 

discussed environmental concerns, including the use of antibiotics, noting the removal a few years ago 

of streptomycin and tetracycline. Kasugamycin is not used in humans and there are no human health 

effects, but it may potentially affect soil biota and grazing animals. The Crops Subcommittee received a 

draft version of the TR in order to review it for this discussion, but the TR is not final yet. The CS will 

put forth a proposal for the Spring 2021 meeting and add questions for public comment.

• Biodegradable Biobased mulch annotation change (AB). The lead circulated several documents 

including prior comments, previous NOSB work, and the NOP-contracted report from Michigan State 

University. The lead asked for feedback from members and will discuss this topic again on the next call. 

• Additional Items. None

• The meeting was adjourned.
