| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good Fit; Tolpyralate has a short half life breaking down quickly in the soil. Low toxicity Non volatile compound:07/23 ; VERY GOOD FIT: RESISTANCE MANAGEMENT.: WSR; VERY GOOD FIT: SEE PREVIOUS COMMENTS: NER
|
| Reasons for need: |
Pigweeds, lambsquater, crabgrass, Italian ryegrass in tank-mixtures; Group 27 herbicides not commonly utilized in tree nut and in tank mixtures with other postemergence herbicides can improve weed control and help with resistance management:07/23; NY/Hazelnuts are an emerging industry in the Northeastern US. Novel weed control tools are needed to support a crop that is trying to become established, nationally:09/23

NJ:Besançon, T ; NY:Sosnoskie, L ; OR:Moretti, M* ;
|
| PCR Use Pattern: |
Make up to 3 directed applications per season to soil and across lower trunks, at least 14 days apart, with last application 30 days before harvest. Follow current Shieldex label for adjuvant type.

| EPA Default Residue Trials: |
|
| IR-4 Residue Trial Plan: |
Any 4; NAFTA, ANY 4 Typically in zone 12;
|
| Residue Protocol Use Pattern: |
USE THE TOLPYRALATE 400 SC PRODUCT (SL-573 400SC) (3.33 LB AI/GAL OF TOLPYRALATE ACTIVE INGREDIENT); MAKE 2 SOIL BANDED APPLIC OF 0.035 LB AI/A, IN 10-50 GPA, AT A 14-DAY INTERVAL AND 30-DAY PHI; APPLIC WILL BE MADE IN A 2-3 FT WIDE BAND EXTENDING OUT FROM THE BASE OF HAZELNUT PLANTS TO BOTH SIDES OF THE ROW WHILE PROPERLY OVERLAPPING THE SPRAY PATTERN ACROSS THE CENTER OF THE ROW TO CREATE A BROADCAST SPRAY PATTERN COVERING A TOTAL 4-6 FT SWATH; DO NOT CONCENTRATE THE TEST SUBSTANCE IN THE SPRAY AREA - THE RATE IS FOR TREATED AREA; ALL APPLIC SHALL INCLUDE A METHYLATED SEED OIL (MSO) AT A CONCENTRATION OF 0.5% V/V OF THE FINAL SPRAY VOLUME
|
| Efficacy/Crop Safety (E/CS) Data Required: |
ISK recommended an additional (3rd) trial is needed:10/24/sb
|
| E/CS Research Comments: |
PER 2024 PERFORMANCE PROTOCOL: ON PLANTS THAT ARE ESTABLISHED FOR AT LEAST 2 YEARS, TESTING SHIELDEX 400 AT 3 RATES (TWO APPLIC [WITH THE FIRST WHEN SUCKERS ARE 3-4" TALL], 14-DAY INTERVAL, UNSHIELDED, 0.026, 0.035, AND 0.07 LB AI/A) VS THE COMBO SHIELDEX + TIAFENACIL, VS TIAFENACIL ALONE, VS ONE APPLIC OF THE 0.035 LB AI/A RATE OF SHIELDEX WHEN SUCKERS ARE 6-8" TALL; MAKE ALL APPLIC BANDED OVER WEEDS ALONG BOTH SIDES OF THE ROWS, IN 10-50 GPA, WITH A METHYLATED SEED OIL (MSO); EVALUATE WEED CONTROL, CROP SAFETY AND CROP YIELD; SEE PROTOCOL FOR MORE DETAILED INFO ON APPLIC PROCEDURES; 2025 PERFORMANCE PROTOCOL FOLLOWS DETAILS OF THE 2024 PROTOCOL
