PRONAMIDE
CORTEVA
CANOLA (20A = RAPESEED SUBGROUP) POTENTIAL: E/CS DATA BEFORE APPROVAL FOR RESIDUE STUDY (02)
Reasons for need: GRASS WEEDS, SPECIFICALLY ITALIAN GRASS; IN WINTER CANOLA PRODUCTION REGIONS OF THE U.S., ITALIAN RYEGRASS AND GRASS WEEDS GENERALLY ARE BECOMING LESS SENSITIVE AND IN MANY CASES RESISTANT TO MULTIPLE HERBICIDES; SEVERAL DIFFERENT HERBICIDE GROUPS WITH DISTINCT MODES OF ACTION REGISTERED FOR CANOLA, INCLUDING GLYPHOSATE, HAVE EXHIBITED PARTIAL OR COMPLETE LOSS OF EFFICACY; PRONAMIDE WOULD PROVIDE A MUCH-NEEDED, ALTERNATIVE MODE OF ACTION TO ENABLE CONTROL OF ITALIAN RYEGRASS AND OTHER GRASS WEEDS IN WINTER CANOLA AND PROVIDE A HERBICIDE STEWARDSHIP OPPORTUNITY FOR GROWERS TO DELAY THE ONSET OF RESISTANCE TO CURRENTLY REGISTERED CHEMISTRIES; AN ADDITIONAL AND NOVEL USE OF PRONAMIDE THAT IS BEING CONSIDERED IS ITS USE AS AN EARLY PRE ON SPRING CANOLA ACRES TO MITIGATE OVERWINTERING GRASS WEED POPULATIONS WHICH FOR MULTIPLE REASONS CAN BE DIFFICULT TO CONTROL EFFECTIVELY IN THE SPRING WITH GLYPHOSATE OR FOP/DIM CHEMISTRIES; THE TANGIBLE ECONOMIC BENEFIT OF CANOLA TO PRODUCERS IS EXTREMELY SIGNIFICANT; AND THE IMPORTANCE OF HAVING EFFECTIVE WEED CONTROL OPTIONS IS CRITICAL TO CONTINUED DOMESTIC PRODUCTION OF CANOLA THAT COUNTERS THE U.S. SUPPLY DEFICIT IN EDIBLE CANOLA OIL AND THE ENORMOUS CANOLA MEAL REQUIREMENTS OF THE DAIRY SECTOR
Efficacy/Crop Safety (E/CS) Data Required:
E/CS Research Comments: RESULTS OF IDAHO TRIAL NOT PROMISING; SHOWED 15.3% REDUCTION IN WINTER WHEAT YIELD RELATIVE TO UNTREATED (AT 48 OZ RATE). CORTEVA WOULD LIKE TO SEE NO CROP ROTATIONAL YIELD LOSS AT 2X RATE FROM MULTIPLE LOCATIONS; FOR OCT 25, 2016 APPLIC- NEED TO KNOW LOCATION, CROP STAGE AT APPLIC, SOIL INFORMATION, PRECIPITATION; MORE WORK NEED TO BE DONE TO ENSURE PLANT-BACK CROP SAFETY BEFORE CORTEVA CAN APPROVE: 12/20
Comments: NO KEY EXPORT MARKET NOTED; THERE ARE NO TOLERANCES FOR PRONAMIDE IN CROP GROUP 20:11/20
