Per Requester: Very Good Fit; Pronamide provides a unique mode of action for management of annual and perennial grass weeds in cranberry, where herbicide options are limited. It complements cultural and mechanical practices, including mowing and sanding, and supports herbicide resistance management by diversifying weed control programs. In addition, pronamide has been used under a Section 18 emergency exemption in Massachusetts cranberries, demonstrating both grower need and the utility of this herbicide in cranberry production systems:06/26;

| Reasons for need: |
Target Pests: * Quackgrass (*Elymus repens*) * Tall fescue (*Festuca arundinacea*) * Orchardgrass (*Dactylis glomerata*) * Perennial ryegrass (*Lolium perenne*) * Italian ryegrass (*Lolium perenne* ssp. *multiflorum*) Primary pest: Quackgrass (*Elymus repens*). Primary pest is perennial grasses. Quackgrass and other perennial grass weeds are difficult to manage in cranberry production and can reduce yield, interfere with harvest operations, and increase production costs. Pronamide would provide an important tool for control of annual and perennial grass weeds and help diversify weed management programs where herbicide options are limited. Current management relies primarily on clethodim, with some suppression from mesotrione:06/26;

| PCR Use Pattern: |
IR-4 suggests applying Kerb SC after winter flood removal and prior to weed emergence only to established cranberry beds at 5 fl oz/A as a single application at use rates of 2.5 to 5.0 pints of product (1.0 to 2.0 lb active) per broadcast acre. Alternatively, two sequential applications of Kerb SC may be made at a rate of 2.5 pints of product (1.0 lb active) per acre. When making sequential applications, allow a minimum of 20 days between applications. Do not exceed a total of 5.0 pints of product (2.0 lb active) per acre per season as a result of single or sequential applications. Kerb SC may be either applied through the irrigation system (chemigation) or through a boom-spray type applicator (at a spray volume of 20 to 50 gallons of water per acre). Boom sprayer applications should be followed by 0.1 to 0.2 inches of irrigation. 75 day PHI.
