| Comments: |
EFFECTIVE NEMATICIDES ARE IMPORTANT TO GROWERS, BUT FUMIGATION IS BECOMING MORE DIFFICULT AS SOME PRODUCTS ARE NO LONGER AVAILABLE; THERE IS CURRENTLY A SUBGROUP 1B TOLERANCE OF 0.3 PPM:11/17; MFG SUPPORTS, BUT NEED PERFORMANCE DATA FIRST; BAYER HAS SOIL APPLIED USES, AND BASF HAS SEED TREATMENT USES:05/18; CANADA HAS EFFICACY DATA THAT CAN BE SHARED (3 TRIALS), AND A CANADA-ONLY RESIDUE STUDY (4 TRIALS IN ZONE 5, 1 TRIAL IN ZONE 1) - MFG SUPPORTS USE OF THOSE DATA TO COMPLIMENT A U.S. PROGRAM; IF RESIDUE WORK IS DONE, AND RESIDUES SUPPORT THE EXISTING SUBGROUP 1B (EXCEPT SUGAR BEET) 0.3 PPM TOLERANCE OR LOWER, MFG IS PREPARED TO MAKE THE SUBMISSION TO EPA:09/18; POTENTIAL: E/CS DATA BEFORE APPROVAL FOR RESIDUE STUDY CHANGED TO E/CS DATA ON-GOING:03/19; MAY NOT NEED RESIDUE DATA FOR CARROT, AS THERE ARE ALREADY SOIL USES ON CARROT:07/19; BASED ON INCONCLUSIVE EFFICACY RESULTS FROM 2019 TRIALS AND THE MFG DECISION ABOUT THE LACK OF VALUE IN SEED TRT FOR NEMATODE CONTROL ON CARROTS, MFG SEES NO COMMERCIAL PATH FORWARD AND NO LONGER SUPPORTS THIS REQUESTED USE:08/20
