TOMATO (PROCESSING) (08-10A = TOMATO SUBGROUP) UNDER EVALUATION (06)
Reasons for need: BRANCHED BROOMRAPE / CURRENT QUARANTINE PEST BUT POTENTIAL FOR SIGNIFICANT YIELD LOSSES IF IT BECOMES ENDEMIC; BRANCHED BROOMRAPE (OROBANCHE RAMOSA) IS AN EMERGING INVASIVE PEST IN CALIFORNIA PROCESSING TOMATO THAT IS CURRENTLY A QUARANTINE PEST; IF IT BECOMES ESTABLISHED, MANAGEMENT TOOLS WILL BE NEEDED TO REDUCE THE YIELD IMPACTS; MANAGEMENT AND CONTROL PROGRAMS ON OROBANCHE SPECIES IN OTHER COUNTRIES HAVE DEVELOPED PROGRAMS BASED ON IMAZAPIC CHEMIGATION FOR EFFECTIVE MANAGEMENT IN TOMATO; IF THERE ARE BARRIERS TO IMAZAPIC REGISTRATION IN CA, IMAZAMOX MAY BE AN ALTERNATIVE ALREADY REGISTERED IN THE STATE; PER CA ME-TOO REQUEST 08/20: BRANCHED BROOMRAPE IS AN EXISTENTIAL THREAT TO THE PROCESSING TOMATO INDUSTRY IN CA, WITH SIGNIFICANT RISKS TO OTHER HOSTS LIKE SUNFLOWERS, SAFFLOWER, BEAN, OLIVE, ETC.; THIS AI IS A PART OF THE ONLY KNOWN LONG TERM MANAGEMENT PROGRAM DEVELOPED FOR THIS PEST
Efficacy/Crop Safety (E/CS) Data Required: BASF REQUIRES MORE COMPELLING CROP SAFETY AND EFFICACY DATA TO MOVE THIS OFF "UNDER EVAL" STATUS:07/20; BASF WOULD ALSO LIKE TO BE INVOLVED IN ANY PROTOCOL DEVELOPMENT FOR 2021 RESEARCH:09/20
E/CS Research Comments:
Comments: REQUESTOR NOTED THIS IS AN EXPORT COMMODITY, BUT NO KEY EXPORT MARKET IDENTIFIED; CROP SAFETY DATA ARE INCLUDED IN IMAZAPIC/SULFOSULFURON PROJECT IS00330; PER BASF, THIS AI IS TOLERANCE EXEMPT SO NO RESIDUE DATA SHOULD BE NEEDED ON PROCESSING TOMATO; BASF HAS INTEREST IN THIS USE, BUT NEEDS MORE COMPELLING CROP SAFETY AND EFFICACY DATA; 2020 TRIAL WORK BY THE REQUESTOR MUST BE EVALUATED BEFORE A PATH FORWARD CAN BE DETERMINED, SO STATUS REMAINS "UNDER EVAL":07/20; IR-4 LIKELY CAN SUBMIT A PETITION FOR EXEMPTION OF TOLERANCE FOR THIS USE, AND RECEIVE THE PRIA FEE WAIVER, PER PRIA CATEGORY R-170:08/20; BASF PREFERS TO KEEP THIS REQUEST "UNDER EVALUATION" AS LONG AS CONTINUATION OF RESEARCH UNDER IR-4 IS00330 PLUS CTRI FUNDING CAN PROCEED IN 2021:09/20; THIS IS EXEMPT FROM TOLERANCE ON TOMATO. SO, EPA INFORMED THAT THIS SUBMISSION WOULD NOT QUALIFY FOR A PRIA FEE WAIVER:03/21; EPA GREEN:08/21

Hanson, Brad 20-CA-DMP RECD 4950.pdf TWO FIELD TRIALS IN 2019-2020. RAPTOR AT 0.137 OZ AI/A APPLIED THROUGH DRIP IRRIGATION AS A PART OF A PICKIT DECISION SUPPORT SYSTEM FOR CONTROL OF BROOMRAPE. RESULTS SHOWED PROMISING EFFICACY. IN A 2ND TRIAL, 2X RATE (9.6 G AI/HA) APPLIED 5X SHOWED NO PHYTOTOXICITY ON TOMATO AND POTENTIAL ROTATIONAL CROPS (BEANS, CORN, MELON, SAFFLOWER, SUNFLOWER, WHEAT).
