PER REQUESTOR, VERY GOOD FIT; RESISTANCE TO MEFENOXAM USED FOR THE CONTROL OF PHYTOPHTHORA CROWN ROT ON STRAWBERRY HAS RECENTLY EMERGED. RESISTANCE HAS BEEN LINKED TO SPECIFIC NURSERY SOURCES. MEFENOXAM AND PHOSPHITE MATERIALS ARE THE ONLY PRODUCTS AVAILABLE FOR PHYTOPHTHORA MANAGEMENT IN NURSERY AND FRUIT PRODUCTION FIELDS. THUS, ADDITIONAL PRODUCTS FROM DIFFERENT FUNGICIDE GROUPS ARE HIGHLY NEEDED. CYMOXANIL HAS BEEN PROVEN EFFECTIVE IN OUR TRIALS AND WOULD BE A GOOD FIT FOR DISEASE AND FUNGICIDE RESISTANCE MANAGEMENT.

| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR THE 2022 FL TRIALS: EVALUATING PRODUCT PERFORMANCE ON COMMERCIAL VARIETIES SUSCEPTIBLE TO PHYTOPHTHORA CROWN ROT AND LEATHER ROT; A FIELD TRIAL WILL EVALUATE CROWN ROT CONTROL DURING THE GROWING SEASON, AND A LAB TRIAL WILL EVALUATE LEATHER ROT CONTROL ON HARVESTED FRUIT; IN THE FIELD TRIAL PLANTS WILL BE INOCULATED WITH CROWN ROT, AND IN THE LAB TRIAL FRUIT WILL BE INOCULATED WITH LEATHER ROT; IN EACH TRIAL 1 FOLIAR USE RATE OF CYMOXANIL (CURZATE 60DF) WILL BE COMPARED WITH A STANDARD; SEE PROTOCOL FOR MORE DETAILS ON TEST SETUP REQUIREMENTS; FOR CROWN ROT EVALUATE DISEASE INCIDENCE, AND FOR LEATHER ROT ASSESS DISEASE INCIDENCE AND SEVERITY; THE 2023 PERFORMANCE PROTOCOL IS SIMILAR IN ALL ASPECTS TO THE 2022 FIELD AND LAB EVALUATIONS - SEE PROTOCOL FOR DETAILS
