|
| Reasons for need: |
Pigweeds, lambsquater, crabgrass, Italian ryegrass in tank-mixtures; Group 27 herbicides not commonly utilized in blueberry and in tank mixtures with other postemergence herbicides can improve weed control and help with resistance management:07/23

| Requesting State(s): |
MT:Miller, Z ; NJ:Besancon, T ; NY:Sosnoskie, L ; OR:Moretti, M* ;
|
| PCR Use Pattern: |
Make up to 3 banded applications at 1- 1.35 fl oz/A along blueberry rows per year, at least 14 days apart, with last application 30 days prior to first harvest. See Shieldex label for guidance on adjuvant type.

| IR-4 Residue Trial Plan: |
1 2-2 5-2 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 FT WIDE BAND EXTENDING OUT FROM THE BASE OF BLUEBERRY 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 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: |
"Previous Oregon trial (XH589) did not show phytotoxicity"
|
| E/CS Research Comments: |
PER 2024 PERFORMANCE PROTOCOL: TESTING SHIELDEX 400 AT 3 RATES (UNSHIELDED, 0.026, 0.035, AND 0.07 LB AI/A) VS THE 0.07 LB AI/A RATE USING A SHIELDED APPLIC, ON HIGHBUSH BLUEBERRY; MAKE ALL APPLIC BANDED OVER WEEDS ALONG BOTH SIDES OF THE ROWS, IN 10-50 GPA, WITH A METHYLATED SEED OIL (MSO); MAKE 2 APPLIC OF EACH TRT 30 DAYS APART, BEGINNING WHEN THE CROP IS FLOWERING; EVALUATE WEED CONTROL, BASAL SHOOT AND FOLIAR CROP SAFETY AND CROP YIELD; SEE PROTOCOL FOR MORE DETAILED INFO ON APPLIC PROCEDURES
