| IPM Compatibility: |
Per Requester: Good Fit; It provides a different mode of action than commonly used postemergence grass herbicides. It helps manage and delay herbicide resistance, particularly in Italian ryegrass. It is typically used as part of an integrated program that includes cultivation, mulches, hand weeding, sanitation, and crop rotation where applicable. Effective grass control can reduce the need for repeated mechanical operations and hand labor:06/26;
|
| Reasons for need: |
Italian ryegrass (Lolium perenne ssp. multiflorum) Perennial ryegrass (Lolium perenne) Quackgrass (Elymus repens) Tall fescue (Festuca arundinacea); primary pest is Italian ryegrass; Italian ryegrass and other grass weeds are increasingly problematic in perennial strawberry production. These weeds compete with the crop, interfere with harvest, and increase production costs. Pronamide would provide an important additional mode of action for grass control and herbicide resistance management; technologies currently used are clethodim, glyphosate, mowing, cultivation between rows - all have limited efficacy:06/26;

|
| PCR Use Pattern: |
Apply Kerb SC to established strawberry plantings from late September to early November after harvest when soil temperatures are cool but above freezing. Apply to moist soil or prior to rainfall/irrigation for optimum activity. Apply at 2.8 L/ha only once per year in pre-emergence, 120 PHI. Do not apply to frozen soils. Best performance is obtained under cool soil conditions and adequate soil moisture following application

Also ref to PR# 00387, but very old and lacks critical info; new request specifically mentions "perennial" strawberries;
