| IPM Compatibility: |
PER REQUESTER, A GOOD FIT. GLUFOSINATE CONTROLS A POPULATION WITH KNOWN PESTICIDE RESISTANCE. THE FOLIAR APPLICATION WILL BE BANDED WITH A SHIELDED APPLICATOR PREVENTING CONTACT WITH CROP FLOWERS AND POLLINATORS.
|
| Reasons for need: |
INCIDENCE OF GLYPHOSATE AND PARAQUAT RESISTANT RAGWEED PARTHENIUM IS RAPIDLY INCREASING IN STRAWBERRY FIELDS AND THERE ARE NO REGISTERED TOOLS AVAILABLE. GLUFOSINATE IS HIGHLY EFFECTIVE ON THIS SPECIES. ALSO, GREEN KYLLINGA IS A PROBLEMATIC WEED IN ROW MIDDLES WITH LIMITED MANAGEMENT OPTIONS AND GLUFOSINATE IS ALSO EFFECTIVE ON THIS SPECIES. THERE IS DATA INDICATING THAT GLUFOSINATE WORKS WELL IN STRAWBERRY AND IS SAFE FOR USE IN THIS CROP.

| Requesting State(s): |
AL:Vinson, E ; CA:Fennimore, S ; FL:Boyd, N* ; IN:Meyers, S ;
|
| PCR Use Pattern: |
RELY AND OTHERS WITH THE SAME RATE AS THE CURRENT LABEL, FOLIAR APPLIED TO WEEDS IN ROW MIDDLES (AREAS BETWEEN RAISED BEDS COVERED IN PLASTIC MULCH) IN 2 APPLICATION WITH A RE-TREATMENT INTERVAL OF 14 DAYS. IN REGARDS TO PHI, THERE SHOULD BE NO APPLICATIONS DURING THE HARVEST PERIOD. APPLY WITH A SHIELDED APPLICATOR TO ROW MIDDLES WHEN WEEDS ARE LESS THAN 4 INCHES TALL. PER REQUESTER, THE LIMITATIONS ARE THAT THERE SHOULD BE NO APPLICATIONS AFTER HARVEST OPERATIONS HAVE BEGUN.

| EPA Default Residue Trials: |
1 2 3 5 10-3 12
|
| IR-4 Residue Trial Plan: |
1 2 3 5 10-3 12; 1 DECLINE
|
| Residue Protocol Use Pattern: |
USE THE LIBERTY 280 SL HERBICIDE PRODUCT (2.34 LB AI/GAL OF GLUFOSINATE-AMMONIUM ACTIVE INGREDIENT); MAKE 1 BANDED TO ROW MIDDLE APPLIC OF 1.59 LB AI/A , IN 15-40 GPA; ALL APPLIC SHALL INCLUDE AMMONIUM SULFATE (AMS) AT A RATE OF 3 LB/A; MAKE APPLIC WITH A SHIELDED OR HOODED SPRAYER BETWEEN BEDS TO THE FIRST SET OF BLOOMS OF THE SEASON JUST BEFORE FRUIT FORMATION; USE ANNUAL STRAWBERRIES TRANSPLANTED IN RAISED BEDS WITH PLASTIC MULCH; DO NOT ALLOW SPRAY TO CONTACT THE PLANTS; THE APPLC RATE IS CALCULATED FOR THE WIDTH OF THE BANDS, NOT THE WIDTH OF THE ENTIRE CROP ROW

| Efficacy/Crop Safety (E/CS) Data Required: |
|
| E/CS Research Comments: |
IN THE PERFORMANCE PROTOCOL FOR 2023 TRIALS: EVALUATING CROP SAFETY AND PERFORMANCE OF GLUFOSINATE FOR WEED CONTROL BETWEEN BEDS OF ANNUAL STRAWBERRIES GROWN IN PLASTIC MULCH; TESTING 2 RATES OF RELY 280 (0.59 AND 1.17 LB AI/A + 3 AND 6 LBS, RESPECTIVELY, OF AMMONIUM SULFATE [AMS]) COMPARED WITH A WEED-FREE UNTREATED; USING A HOODED/SHIELDED SPRAYER, MAKE 3 BANDED APPLIC OF EACH TREATMENT TO ROW MIDDLES IN >15 GPA, 14-DAY INTERVALS, WITH 1ST APPLIC AFTER TRANSPLANTED PLANTS ARE ESTABLISHED, AND LAST APPLIC BEFORE FRUIT FORMATION; MAKE APPLIC TO THE SOIL AND EMERGED WEEDS ON BOTH SIDES OF STRAWBERRY BEDS, MAKING SURE NOT TO CONTACT PLANTS; EVALUATE CROP SAFETY AND YIELD; WEED CONTROL DATA ARE NOT REQUIRED; 2024 PERFORMANCE PROTOCOL FOLLOWS DETAILS OF THE 2023 PROTOCOL
