| Reduced Risk Status: |
|
| IPM Compatibility: |
PER REQUESTOR: VERY GOOD IPM FIT; THERE ARE CURRENTLY NO FUNGICIDES REGISTERED FOR STEVIA AND THIS PRODUCT WILL BE AN IMPORTANT PART OF DEVELOPING IPM PROGRAMS FOR THE CROP; PYRACLOSTROBIN IS USED IN OTHER CROPS AND IS WELL ESTABLISHED AS NONTOXIC TO BENEFICIAL INSECTS INCLUDING BEES; THE ADDED SDHI COMPONENT OF THIS PRODUCT WILL REDUCE SELECTION PRESSURE FOR FUNGICIDE RESISTANCE:06/18
|
| Reasons for need: |
SEPTORIA STEVIAE; NEEDED TO REDUCE LEAF LESIONS AND YIELD LOSS; SEPTORIA LEAF SPOT IS ONE OF THE MOST IMPORTANT PATHOGENS OF STEVIA IN THE U.S.; STEVIA IS HARVESTED FOR ITS LEAVES AND SEPTORIA LEAF SPOT CAN COMPLETELY DEFOLIATE PLANTS PRIOR TO HARVEST LEADING TO HUGE YIELD LOSSES; THERE ARE NO FUNGICIDES REGISTERED FOR STEVIA AND HAVING PRODUCTS TO MANAGE S. STEVIAE IS CRITICAL TO EXPANDED PRODUCTION OF THIS CROP IN THE U.S.

| Requesting State(s): |
NC:Shew, H. D. ;
|
| PCR Use Pattern: |
USE THE PRIAXOR PRODUCT; MAKE 2 FOLIAR APPLIC OF 3.4 OZ AI/A, 14-21 DAY INTERVAL; NO PHI NOTED; APPLY ONCE MEAN % LEAF AREA COVERED BY LESIONS REACHES 5%, BEFORE EXTENSIVE LEAF DAMAGE HAS OCCURRED
|
| EPA Default Residue Trials: |
|
| IR-4 Residue Trial Plan: |
ANY 4 (DRY ONLY), 1 DECLINE
|
| Residue Protocol Use Pattern: |
USE THE PRIAXOR XEMIUM BRAND FUNGICIDE PRODUCT (1.39 LB AI FLUXA + 2.78 LB AI PYRAC/GAL); MAKE 2 FOLIAR APPLIC OF 8.0 FL OZ PRODUCT/A, IN 30-100 GPA, 14-DAY INTERVAL, 0-DAY PHI; ALL APPLIC SHOULD INCLUDE A LABEL RATE OF ADJUVANT UNLESS ABSENCE OF ADJUVANT IS BEING USED TO DIFFERENTIATE MORE THAN 1 TRIAL BY THE SAME FRD
|
| Efficacy/Crop Safety (E/CS) Data Required: |
MFG REQUIRES 2 PRODUCT PERFORMANCE TRIALS (BOTH CROP SAFETY AND EFFICACY), WITH MULTIPLE TREATMENTS TO COVER 1X, 2X AND 4X USE RATES:09/18; BASF CONFIRMED THAT SUFFICIENT EFFICACY/CROP SAFETY DATA HAS BEEN PROVIDED, AND NO MORE IS NEEDED:01/08/20
|
| E/CS Research Comments: |
PER 2019 PERFORMANCE PROTOCOL: TESTING PRIAXOR XEMIUM BRAND FUNGICIDE AT 8, 16 AND 32 FL OZ PRODUCT/A (1X, 2X, 4X) VS THE STANDARD ELATUS (AZOXYSTROBIN + BENZOVINDIFLUPYR), 2 FOLIAR APPLIC AT A 14-DAY INTERVAL STARTING WHEN FAVORABLE CONDITIONS BEGIN FOR SEPTORIA LEAF SPOT, 30-100 GPA; EVALUATE DISEASE INCIDENCE AND SEVERITY ON FOLIAGE AT EACH APPLIC AND AT 2-WK INTERVALS TILL TRIAL CONCLUSION; ASSESS CROP SAFETY (AT 1, 2, 4 WK AFTER 1ST APPLIC AND AT TRIAL CONCLUSION); AND ASSESS YIELD, SIMULATING A STANDARD HARVEST AND A LATE-SEASON HARVEST
