### !

The registrant is seeking a new product registration for Ritter Dicamba Technical. The product is substantially similar (identical?) to a currently registered product (42750-57) and the registrant is using the "cite-all" method of support. A basic formulation dated 

### 9/6/11 (replaces the 

### 3/111111 CSF) was submitted as well as GroupA data

.. This review has been altered subsequent to the contractor's signatures. SUMMARY OF FINDINGS: 1. The registrant submitted a Confidential Statement of Formula (CSF) for the basic fonnulation 

### (3/11/2011). The product chemistry data corresponding to guideline reference 830.1550 (product identity & composition) submitted on the CSF satisfy the data requirements of40CFR§158.155. The data corresponding to guideline reference 830.1750 (certified limits) satisfy the requirements of 40CFR§158.175 [MRID No. 484205-01]. The content ofactive ingredient given on the CSF for the basic formulation matches the label. 2. The product chemistry data submitted corresponding to guideline reference 830.1600 (description of material used to produce the product) satisfy the data requirements of40CFR§ 158.160 [MRID No. 484205-011· 3. The product chemistry data submitted corresponding to guideline reference 830.1620 (description of production process) satiSfy the data requirements for 40CFR§158.162 [MRID No. 484205-01].BARCODE: 388021; Reg. No./FllE SYMBOL No.:9468-UL; PRODUCT: Ritter Dicamba Technical
4. The product chemistry data submitted corresponding to guideline reference 830.1670 (discussion of the formation of impurities) satisfy the data requirements for 40CFR§158.167 [MRlD No. 484205-01]. 5. The product chemistry data submitted corresponding to guideline reference 830.1700 (preliminary analysis) to support the claims on the CSF satisfy the data requirements of40CFR§158.170 [MRID No. 

### 484205-021· 6. The product chemistry data submitted corresponding to guideline reference 830.1800 (enforcement analytical method) satisfy the data requirements of40CFR§158.180 [MRID 484205-02]. 7. The data submitted corresponding to guidelines 830 Series Subgroup B (physical-chemical properties) satisfy the data reqUirements of40CFR§158.190 [MRID No. 484205-03 and 484205-04]. Waivers were requested for explodability and flammability. Provision ofcorrosion characteristics and storage stability will be conducted if requested by the Agency. CONCLUSIONS: The TRB has reviewed the product chemistry data submitted for Ritter Dicamba Technical (produced by Ritter Chemicals, LLC) and has concluded that: 1. The product chemistry data submitted for guideline 830 Series groupA are acceptable, except for

impurities of potential concern. 2. The product chemistry data corresponding to 830 series group B (physical-chemical properties) are acceptable. 3. The proposed CSF for the basic formulation dated September 6, 2011 (replaces the March 11,2011 CSF) is acceptable. The registrant listed all the known potential impurities oftoxicological COncern on the CSF. The total amount of unidentified impurities is 4. This product is substantially similar to product EPA Reg. No. 42750-57. However, this product listed all potential toxic impurities on the CSF

A basic CSF dated March 11, 2011, a label and company letter are included in the submission. A search ofthe OPP electronic databases showsthat six acute toxicity studies were submitted to supportthe reregistration ofthe cited product, 42750-57. They were reviewed and classified as acceptable ina Product Reregistration Branch memo (Dupuy; D363560; 16/APRJ2009).


### RECOMMENDATIONS: 

## 1. TRB compared the fonnulations of the proposed product, 9468-UL and the cited product, 42750-57, and concluded thatthetwo products are substantially similar. 2. The acute toxicity profile for the proposed product, Ritter Dicamba Technical, EPA File Symbol 9468-UL, is as follows: acute oral toxicity III 

### cited EPA Reg. No. 42750-57 acute dermal toxicity 

### IV cited EPA Reg. No. 42750-57 acute inhalation toxicity 

### IV cited EPAReg. No. 42750-57 primary eyeirritation 

### I cited EPAReg. No. 42750-57 primary skin irritation 

### IV cited EPAReg. No. 42750-57 dermal sensitization negative cited EPA Reg. No. 42750-57 3. This memorandum pertains only to the decision concerning whether the subject product is similar to the cited product from an acute toxicological view point. For the purposes of this action, TRB has made no further determination ofthe adequacy ofthe toxicological data base or the precautionary label ofthe cited product. 4. The proposed basic CSF submitted for 9468-UL must be accepted by the TRB Product ChemistryTeam.

I received this letter (attached) in the mail but I really don't believe that the PRIA category should be R300. Every application for registration of a me-too technical has typically been R310. Is there something different about this application that makes it an R300?

### Endnotes for Data Matrixfor Ritter Dicamba MUP

1 830.1650 _These data are not required for the registration ofa technical product. See 830.1620 for production process information. 2830.6313 _Ritter Chemica!, LLC requests a waiver from the stability to metal and metal ion portion of this data requirement. Ritter Chemical, LLC does not intend to package Oicamba Technical in metal containers, nor is Dicamba Technical expected to come into contactwith metals or metal ions during its 

### storage or use. Therefore, a waiver from the requirement of these data is requested. Dicamba Technical was found to be stable at normal and elevated temperatures (these data are reported separately and is part ofthis submission). 3830.6315 _ Ritter Chemical, LLC requests a waiver from the requirement ofthis data requirement since Dicamba Technical is a solid and does not contain any ingredients that are flammable. Please refer to the Confidential Statement of Formula for Dicamba Technical. 4830.6316 _Ritter Chemical, LLC requests a waiver from this data requirement. Dicamba does not have the chemical bonds orfunctional groups associated with explosive chemicals. 5830.6317, 830.6320 _Per PR Notice 92-5, storage stability and corrosion characteristics data are not required to be submitted unless specifically requested by the Agency. Ritter Chemical, LLC has initiated these studies and will submit the final report when available. 6830.6319 _ This data requirement is required when the MUP is an emulsifiable liquid and to be diluted with petroleum solvents. Ritter Dicamba Technical is not an end-use product. Therefore these data are not required for Ritter Dicamba Technical. 7830.6321,830.7100
- Dielectric breakdown data are required ifthe product is an end-use product. This data requirement is not applicable Ritter Dicamba Technical. Viscosity is required for liquid products and is not applicable to the solid Ritter Dicamba Technical. 8830.7220 _ This data requirement is not applicable to Ritter Dicamba Technical because it is a solid. Refer to guideline 830.7200 for melting point data.
9 830.7300 _ Ritter Chemical, LLC conducted bulk density with Ritter Dicamba Technical. The bulk density is 0.703 

### g/mL. The public literature density for dicamba acid is reported to be 1.488 (Ref. (Reference: Tomlin. "The Pesticide Manual''. 13th Edition, p. 279. BCPC Publications, Hampshire, 2003). However, EPA documents (docket EPA-HQ-OPP-2005-0479-005) indicate that the relative density is 1.57 which was obtained from a technical material that was only 87% pure. EPA cited data from the 6/30/89 Reregistration Standard. The bulk density of the Ritter Dicamba Technical me-too technical dicamba acid must be similar to the value obtained for Ritter Dicamba Technical: Tacoma Ag, LLC's Dicamba Acid Technical, EPA Reg. No. 83520-8, is also a me-too ofthe same cited product (based on information in the Registration Jacket for 83520-8) and the bulk density of the Tacoma Ag, LLC's technical product is 0.608 g/mL (see MSDS in Attachment 1). The bulk density values for Ritter Dicamba Technical and Tacoma Ag LLC's technical are similar. Therefore, the bulk density for Ritter Dicamba Technical should not be compared to data in the public literature since that data is for relative density and from an 87% pure technical material. 10 830.7520 _ Ritter Chemical. LLC is seeking a waiver for this data requirement. Ritter Dicamba Technical is not a fibrous material nor is it water insoluble.
