| Reduced Risk Status: |
THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
|
| IPM Compatibility: |
PER REQUESTER: VERY GOOD FIT; ADDING A NEW CROP TO THE SYSTEM INCREASES BIODIVERSITY. THIS HERBICIDE IS AN ADDITIONAL MODE OF ACTION TO REDUCE THE HERBICIDE RESISTANCE ISSUES OCCURRING IN THE CORN AND SOYBEAN ROTATION:08/22
|
| Reasons for need: |
HARVEST AID/DESICCATION; SINCE SOYBEANS ARE OFTEN PLANTED AFTER HARVEST, AN EARLIER HARVEST DATE WOULD ALLOW FOR AN EARLER SOYBEAN PLANTING DATE. IN ADDITION, AN EARLIER HARVEST WOULD HELP REDUCE YIELD LOSS ATTRIBUTED TO THE SEED SHATTERING PROBLEMS ASSOCIATED WITH THIS CROP. THIS PRODUCT IS AN ADDITIONAL MODE OF ACTION TO CONTROL WEEDS;

IL:Bernards, M ; MO:Aulbach, C ; SD:Reicks, G* ;
|
| PCR Use Pattern: |
DOSAGE 1-2 OZ/A, FOLIAR BROADCAST, APPLY TO PHYSIOLOGICALLY MATURE CROP, USE A MINIMUM OF 5-10 GAL/A SPRAY VOLUME, FOR OPTIMAL PERFORMANCE, APPLY 1 GAL MSO PLUS 8.5-17 LB AMS/100 GAL SPRAY SOLUTION. IF SOYBEANS ARE PLANTED IMMEDIATELY AFTER PENNYCRESS HARVEST, THE RATE MAY BE REDUCED TO 1 OZ/A. THIS IS THE LABELED RATE FOR PREGEMERGENCE APPLICATION TO SOYBEAN; DO NOT USE IF SOYBEANS WILL FOLLOW PENNTCRESS ON COARSE SOILS WITH <2% ORGANIC MATTER

| E/CS Research Comments: |
PER THE 2024 PERFORMANCE PROTOCOL: EVALUATING PRODUCT PERFORMANCE AS A HARVEST AID/DESSICANT; TESTING 2 RATES OF SHARPEN HERBICIDE: 0.022 AND 0.044 LB AI/A, APPLIED FOLIAR BROADCAST IN AT LEAST 10 GPA, VS A LABELED RATE OF REGIONE (DIQUAT); APPLY SHARPEN TREATMENTS AFTER CROP HAS REACHED PHYSIOLOGICAL MATURITY, 3-10 DAYS PRIOR TO SEED HARVEST; ALL SHARPEN APPLIC MUST INCLUDE A METHYLATED SEED OIL (MSO) AT 1% V/V, AND AMMONIUM SULFATE (AMS) AT 17 LB/100 GAL OF SPRAY SOLUTION; EVALUATE CROP DESSICATION AT 3 AND 7 DAYS POST APPLIC, AND AT HARVEST; SEED VIABILITY WILL ALSO BE ASSESSED; WEED CONTROL AND CROP YIELD DATA ARE NOT REQUIRED; 2025 PERFORMANCE PROTOCOL FOLLOWS DETAILS OF THE 2024 PROTOCOL

| Comments: |
CHEMSAC PROPOSAL WILL BE DONE FOR POTENTIAL RESIDUE TOLERANCE:10/22; STATUS OF "RESEARCHABLE, RESIDUE & E/CS DATA NEEDED" SHOULD HAVE BEEN UPDATED TO BASF SUPPORTS "NEEDS E/CS DATA ONLY" IN 9/22. THE STATUS HAS SINCE BEEN CHANGED TO "TOLERANCE/USE TO PURSUED WITH NO DATA PROPOSAL/PETITION" SINCE IR-4 WILL PREPARE A CHEMSAC PROPOSAL. ALSO, IR-4 E/CS WORK IS EXPECTED TO BE CARRIED OUT IN 2024:07/23/sb; AN E/CS PROTOCOL WAS SIGNED 9/5/23 FOR 2024 TRIALS, SO THE STATUS HAS BEEN UPDATED TO E/CS DATA ONGOING. THE RES CHEMSAC PROPOSAL WILL STILL BE TRACKED ON THE IR-4 TIMELINES:02/24/sb; THE RES PETITION HAS BEEN SUBMITTED 05/24/drs; No data petition/chemsac was sub to EPA:05/24/sb; Notice of Filing (Tolerance Proposals) Published in the Federal Register:11/24/sb; leaving status as is due to continued E/CS ongoing:12/24/sb;
