| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Very Good Fit; The use of another FRAC group will help prevent resistance in pathogen populations. It can be alternated with other FRACs:09/23
|
| Reasons for need: |
Colletotrichum, Alternaria, Pestalotiopsis, Cephaleuros (algae); Guava acreage is increasing, there are few active ingredients labeled which do not cover the extended fruiting season of this crop (~5-6 months from flowering) - two harvests per year. There is a need for a different FRAC that can be use in a rotation program:09/23

| Requesting State(s): |
FL:Gazis Seregina, R* ;
|
| PCR Use Pattern: |
Use Miravis Prime; 3.4 fl oz/A; Foliar spray; 8 applications; RTI: 14 days; PHI:30 days; Syngenta would support 13.4 fl oz/A (not 3.4 fl oz/A) at total of 2 (not 8 applications) foliar applications, 14-day RTI and 30-day PHI for Alternaria control. There would need to be efficacy data provided for this crop if registration is needed in CA. And, If the DFU’s match, Syngenta already has a tolerance established for fludioxonil on guava for 5.0 ppm (IR-4 study 07127 where applications of Switch 62.5 WG were applied 4X at 0.219 lb FDL/A. There are RTIs at 7 days, 21 days, and 7 days between each application and a PHI of 0 days):09/23

| EPA Default Residue Trials: |
3/10/13-4
|
| IR-4 Residue Trial Plan: |
ANY 4. 2025 - 3 RED A (2 NEED & 1 BACKUP) TRIAL
|
| Residue Protocol Use Pattern: |
USE THE MIRAVIS PRIME PRODUCT (1.25 LB AI OF PYDIFLUMETOFEN AND 2.09 LB AI OF FLUDIOXONIL ACTIVE INGREDIENTS/GAL OF PRODUCT); MAKE 2 FOLIAR DIRECTED APPLIC OF 396 ML PRODUCT/A (0.0131 LB AI PYDIFLUMETOFEN + 0.219 LB AI FLUDIOXONIL/A), IN 50-150 GPA, 14-DAY INTERVAL, 30-DAY PHI; ALL APPLIC SHALL INCLUDE A LABELED RATE OF AN ADJUVANT

| Efficacy/Crop Safety (E/CS) Data Required: |
|
| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR 2024: EVALUATING PRODUCT PERFORMANCE ON COMMERCIAL VARIETIES SUSCEPTIBLE TO PESTALOTIOPSIS/COLLETOTRICHUM IN GUAVA; TESTING FOLIAR APPLIC OF 13.4 FL OZ/A OF MIRAVIS PRIME (PYDIFLUMETOFEN + FLUDIOXONIL) VS THE LABELED STANDARD AZOXYSTROBIN (APPLIED PER LABEL DIRECTIONS); MAKE 2 FOLIAR APPLIC, WITH 1ST APPLIC BEFORE DISEASE DEVELOPMENT, AND 2ND APPLIC 14 DAYS LATER, 30-DAY PHI; EVALUATE FRUIT DISEASE SEVERITY AND INCIDENCE, AS WELL AS FRUIT AND FOLIAGE INJURY

Mfg supports as "Researchable, Residue & E/CS Data Needed", with data needed on colletotrichum, algae & pestalotiopsis, and If the DFU’s match, Syngenta already has a tolerance established for fludioxonil on guava for 5.0 ppm (IR-4 study 07127 where applications of Switch 62.5 WG were applied 4X at 0.219 lb FDL/A. There are RTIs at 7 days, 21 days, and 7 days between each application and a PHI of 0 days):09/23; EPA 13776, 12/23; Status changed from "Researchable, Residue & E/CS Data Needed"to "E/CS ongoing" 02/24/DRS; Status changed to "Residue ongoing ECS ongoing" 03/24/DRS;
