AMVAC Chemical Corporation Announces New Registrations for Two Soil Insecticide Products

We recently learned that AMVAC Chemical Corporation has received federal registrations for two new soil insecticide products. Both products contain active ingredients that have been in the soil insecticide marketplace for many years.

Counter Smartbox 20G contains the active ingredient terbufos. This formulation, which will replace the 15G formulation over the next several years, is not related to the CR formulation once marketed and sold across the Corn Belt. This product will be delivered through the SmartBox and Lock'n Load application systems. Recommended rates of application for Counter Smartbox 20G vary depending on whether a Bt corn rootworm hybrid is planted. If a Bt corn rootworm hybrid (field corn) is planted, the insecticide may be applied in a band over the row or in furrow at a rate of 4.5 to 6.0 ounces per 1,000 feet of row. According to the label, "Rates less than 6 ounces per 1,000 feet of row are recommended for suppression only, unless used in combination with a corn hybrid containing in-plant corn rootworm protection traits." Please consult the Counter Smartbox 20G label for more detailed product information and application instructions.

SmartChoice 5G contains the active ingredients chlorethoxyfos (4.3%) and bifenthrin (0.7%). The primary organophosphate ingredient is the same active ingredient of Fortress, a product that will be phased out of the marketplace. AMVAC anticipates SmartChoice being available in limited quantities via SmartBox containers this growing season. SmartChoice should be delivered in-furrow at planting. When used at a rate of 3.0 to 3.5 ounces per 1,000 feet of row, the product "aids in the control of corn rootworm larvae when used in combination with corn hybrids containing in-plant protection against corn rootworm larvae." A rate of 4.5 to 5.0 ounces per 1,000 feet of row should be used against corn rootworm larvae when a non-Bt corn rootworm hybrid is planted. For more detailed information, please consult the label. --Mike Gray and Kevin Steffey
