(Millions of Pounds A.I.) 
A VALUABLE WEED CONTROL TOOL

• Characteristics of glyphosate make it versatile and flexible

– Broad spectrum control of grass and broadleaf weeds

– Post-emergence activity enables application any time weeds 

are present and actively growing

– Absence of soil residual activity provides many options for 

cropping systems

• Facilitates increased adoption of conservation tillage practices

• Selective application equipment (wiper, hooded / shielded 

sprayer, injection) increases on-target application

• Diversity of registered uses reflects these characteristics

11/08/2012 3
USE MATRIX – SELECTION CRITERIA

• Primary originality

• Timeframe when registered as a me-too

• Whether registrant has reorganized / amended label

• Whether registrant has authored different text

• Specificity of directions 

• Inclusiveness of application rates and equipment types

• Breadth of uses registered

– Example: Some residential registrations have relatively narrow use patterns 

– about 50 screened and found to be represented by much smaller set of 

selected labels

• Eliminated products with identical/nearly identical label language

• Various formulations and glyphosate salts (normalized by 

glyphosate acid equivalent)

USE MATRIX - STATUS

• Over 40 spreadsheets categorized by crop, sets of 

crops, non-crop terrestrial, aquatic and residential/ 

consumer use patterns

• Approximately 85% complete

– Agricultural essentially done

– Non-crop, aquatic and residential in progress

• Target deadline? Early 2013

• Matrix summary exemplifies range of registered 

products and labels

• Matrix summary rates normalized to glyphosate

a.e.

11/08/2012 9
USE MATRIX – DATA GAP FILLING

• Application Rates

– Maximum single rate at various timings

– Option to split single rate into lower sequential rates

– Maximum number of applications per crop cycle 

– Maximum application rate per year

– Maximum annual rate for all applications combined

• Intervals

– Retreatment (RTI)

– Preharvest (PHI)

– Pregrazing (PGI) 

– Plantback (PBI)

Group Review

11/08/2012 11
USE AND USAGE DATA

• Label information addressed by label use matrix

• Median and 90th percentile rates?

– How much rate data is needed?

– Might there be an EEC related to a specific rate that is 

protective in comparison to relevant ecotox endpoints?

– Lower rate data therefore less needed?

• Market research or other use data collection?

– Prioritization of uses (effort versus value)?

– What are acceptable data sources for minor / specialty 

uses? 

– Groups of crops for bigger bucketing?

11/08/2012 12
PERCENT CROP TREATED DATA

• Use distribution (acreage, geographical distribution and 

geographical limitations)

– How to address broad range of uses with glyphosate?

• Market research or other usage data collection?

• Sub-county information and EPA’s expectation of 

“completeness”?

• Groups of crops?

• Challenges within JGTF

– Not all members subscribe to market research data services

– Regulatory utility of information unclear versus cost

11/08/2012 13
QUESTIONS/DISCUSSION WITH EPA

• Timelines for remainder of Registration Review

– EFED work plan/E-Fate assessments?

– Deadline for use matrices? (inputs for assessments)

• Questions/Outstanding Items

– Scope and timing of future Focus meetings 

– Catch up DCIs needed for new registrant

– Means to compel label changes?
