Agricultural Use Requirements
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE)and restricted-entry interval. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 24 hours. PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has treated, been such as plants, soil or water, is: ! Coveralls over short-sleeved shirt and short pants ! Waterproof gloves ! Chemical-resistant footwear plus socks ! Chemical-resistant headgear for overhead exposure General Information Kerb 50-W herbicide is effective for the control of a wide range of grasses and certain broadleaf weeds. The product is a soil active herbicide with uptake by sensitive weeds occurring through the roots. Timing and Application: Kerb 50-W should be applied in the fall or early winter, when temperatures do not exceed 55"F, but prior to freeze-up. Best weed control results occur when Kerb 50-W is applied preemergence to the weeds and when application is followed by rainfall or irrigation to move the product into the root zone of the germinating weeds. Effect of Soil Type, Moisture and Temperature: Kerb 50-W is most active in coarse to medium textured soils of low organic matter and relatively inactive in peat or muck soils or mineral soils high in organic matter content at rates recommended in this label. Herbicidal activity is best in soils containing less than 4 percent organic matter. Use in soils with higher organic matter may result in inconsistent or incomplete weed control. The herbicidal activity of Kerb 50-W is mainly through root absorption in sensitive weed species. Rain, melting snow or irrigation is essential following treatment to move Kerb 50-W into the root zone of germinating weeds. Under field conditions, Kerb 50-W will remain relatively stable with little loss of herbicidal activity when soil temperatures are less than 55"F. As soil temperatures increase, degradation of the active ingredient takes place. Kerb 50-W may degrade rather quickly if left exposed on the soil surface in warm weather. If Kerb 50-W is applied when air temperatures exceed 85"F, it should be soil incorporated to a shallow depth (top two ...
