Posted 16 August 2005. Crop Management. GAUCHO Now Available to Soybean Growers for Protection Against Soybean Aphids and Bean Leaf Beetles Bayer CropScience. Research Triangle Park, NC (August 8, 2005) - Soybean growers have a new line of defense against soybean aphids and bean leaf beetles. GAUCHO® seed-applied insecticide from Bayer CropScience is now registered for use on soybean seed by the U.S. Environmental Protection Agency (EPA). Soybean seed treated with GAUCHO is approved for immediate sale and use within the United States. For the past two years, the EPA granted approval of a Section 18 emergency use registration of GAUCHO for soybeans in selected states. "We are excited about this registration of GAUCHO for application to soybean seed," says Paul Holliday, product manager for Bayer CropScience. "GAUCHO is a proven performer in many crops and performed very successfully on soybean acres in 2003 and 2004 under the Section 18 registrations." GAUCHO seed-applied insecticide has systemic properties that make it valuable in controlling piercing/sucking insects. The use of GAUCHO on soybean seed will control early season aphids up to 65 days after planting by reducing aphid populations below economic threshold. "Early season aphid infestations have been identified as causing a reduction in pod numbers on the soybean plant," says Ray Knake, technology development manager with Bayer CropScience. When conditions are favorable for aphid reproduction and survival, which result in aphid numbers above threshold, a later-season insecticide spray may also be warranted. "GAUCHO is also a smart choice for growers concerned about bean leaf beetles," Holliday says. GAUCHO reduces bean leaf beetle feeding and aids in reducing the bean pod mottle virus carried by over-wintering populations of the beetle. Holliday recommends GAUCHO as part of a comprehensive soybean management program. "GAUCHO is designed to be part of an overall bean leaf beetle management program that includes foliar sprays of the true first generation beetles," he says. If soybeans are planted very early, the activity of GAUCHO may decrease below an effective level before the last over-wintering beetles have completed their life cycle. Field research has shown that using GAUCHO on soybean seed not only reduces insect damage to the plants but can lead to increased yields as well, adds Knake. An increasing number of products are being applied to soybean seed in an attempt to control problems at planting. These products include seed inoculants, fungicides and insecticides. GAUCHO seed-applied insecticide is compatible with rhizobium inoculant and fungicide systems including SoyGard®, SoyGard L® with Protégé® and ApronMaxx® seed treatments. GAUCHO will be widely available for the 2006 growing season. Growers who want the additional protection provided by GAUCHO should contact their soybean seed supplier, Holliday says, since the insecticide is applied directly to the seed by seed companies and seed conditioners. As with any crop protection product, always read and follow label instructions.
