| IPM Compatibility: |
PER REQUESTER: GOOD IPM FIT; RESISTANCE MANAGEMENT OPTION, FITS CULTURAL PRACTICES, COMPLEMENTS CULTURAL AND MECHANICAL CONTROL:11/19
|
| Reasons for need: |
GRASS WEEDS; BETTER GRASS CONTROL, INCREASE AVAILABILITY OF PESTICIDE OPTIONS; PER ND ME-TOO REQUEST 07/20: GROWERS IN MN/ND ARE DESPARATELY LOOKING FOR ALTERNATIVE HERBICIDES SO THEY HAVE MORE THAN ONE FOR EFFICIENT WEED CONTROL WITHOUT RESISTANCE DEVELOPING; PER ND ME-TOO REQUEST 08/20: THERE IS A HIGH DEMAND FOR NEW CHEMICALS FOR USE IN BUCKWHEAT FOR BROADLEAF AND GRASSY WEEDS; SOLUTIONS ARE NEEDED, OR BUCKWHEAT PRODUCTION COULD DISAPPEAR

| Comments: |
SPECIFICALLY, "TAME" BUCKWHEAT; NO KEY EXPORT MARKETS NOTED; MAY BE ABLE TO EXTRAPOLATE TOLERANCE FROM EXISTING TOLERANCES ON BARLEY (0.05 PPM ON BARLEY GRAIN, HAY AND STRAW):11/19; REQUESTER IS WITHDRAWING REQUEST AND A NEW REQUEST WILL BE SUBMITTED FOR A DIFFERENT CHEMICAL:01/20; PER IR-4 DISCUSSION WITH INTERESTED STAKEHOLDERS, STATUS WAS CHANGED BACK TO RESEARCHABLE; THERE IS SOME CONCERN ABOUT WEED RESISTANCE TO QUIZALOFOP, BUT IF USE CAN BE ACHIEVED VIA EXTRAPOLATION FROM BARLEY TOLERANCES, IT WILL BE GOOD TO PURSUE THE USE:02/20; BARLEY TOLERANCES CAN BE USED TO SECURE TOLERANCE FOR BUCKWHEAT, BUT KEEP AS RESEARCHABLE TO SECURE EPA REVIEW AND ALLOW STAKEHOLDER PRIORITIZING:05/20; EPA GREEN: 08/20; AMVAC CONFIRMED NO E/CS DATA ARE NEEDED:05/21; EPA GREEN: 08/23
