MEFENTRIFLUCONAZOLE ( BASF ) BROCCOLI ( 05-16 = BRASSICA HEAD AND STEM VEGETABLE GROUP ) RESIDUE ON-GOING; E/CS DATA ON-GOING (03M ) AZ; OR; VA;


Reasons for need: Alternaria leaf spot (ALS); The disease is of growing concern to growers nationwide particularly in the Southwestern US/Coastal CA because of decreasing efficacy of narrow number of chemical fungicides available to control the disease. Furthermore due to the limited available chemistries the risk of pathogen resistance to the limited modes of action is considerably large. The goal of this study shall be to generate efficacy and phytotoxicity data to support the registration of Cevya (mefentrifluconazole) to control ALS:08/23; VA/Disease is of high concern for Southeastern growers. Limited availability of chemistries for resistance management:09/23
Residue Data Sites: 6 10-4 12 (decline); NAFTA, 5-2, 10-6
Performance Data Required: MFG requires both E and CS data from at least 3-4 trials in California to generate the required data to secure registration with CA-DPR
Use Pattern: Apply Cevya at 5 fl oz/A as a foliar spray 3 times every 7 days, PHI = 0 days.
Comments: Requester is looking for CA registration:08/23; Mfg supports as "Researchable, Residue and E/CS data needed" & mfg suggests adding additional decline sampling points for the RAC in the MOR trials to evaluate residue data from multiple PHI and offers to conduct the analytical phase of the residue program.:08/23/sb; EPA Green, 12/23; Residue signed 12/23. perf. not signed: 12/23 JPB; perf protocol signed, status changed from "complete w ongoing trials" to "Residue ongoing e/cs ongoing" 02/24/drs;
State Requestor: AZ:Hu, J* ; OR:Ocamb, C ; VA:Higgins, D ;
