Evaluation of Bt Corn and Soil-applied Insecticides for Management of Corn Rootworm Larvae
Introduction The purpose of this study was to evaluate the effectiveness of Bt corn, with and without soil insecticides, for management of corn rootworm. Evaluation of Bt hybrids included Agrisure 3000GT, Agrisure 3122 RIB, DeKalb YieldGard VT3, and Pioneer Optimum AcreMax1. Soil insecticides evaluated were Aztec 2.1G, Aztec-SB 4.67G, Capture LFR 1.5SC, Counter-SB 20G, Force 250CS, and SmartCho...
متن کاملInfluence of western corn rootworm (Coleoptera: Chrysomelidae) larval injury on yield of different types of maize.
Two field experiments were conducted in 1995-1996 to determine if there are common yield responses among maize hybrids to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. Three yellow dent hybrids, five white food grade dent hybrids, and a popcorn hybrid were included in the study. The minimum level of rootworm injury as measured by root damage ratings (3.2-4.2) that...
متن کاملBt Corn Rootworm Protected Corn: Performance and Resistance Management
Although field corn pest management has remained largely dependent on restricted-use, broad-spectrum insecticides (organophosphates, carbamates and pyrethroids) for corn rootworm control, this situation is changing rapidly with the 2003–2004 market entry of highly selective tactics, including genetically modified Bt rootworm corn hybrids and nicotinoid insecticidal seed treatments labeled for c...
متن کاملEffect of Bt maize and soil insecticides on yield, injury, and rootworm survival: implications for resistance management.
A 2-yr field experiment was conducted to determine the effects on Diabrotica spp. (Coleoptera: Chrysomelidae) of an insecticidal seed treatment (Poncho 1250, (AI)/clothianidin) and a granular insecticide (Aztec 2.1G, (AI)/tebupirimphos and cyfluthrin) alone and in combination with maize producing the insectidical toxin Cry3Bb1 derived from the bacterium Bacillus thuringiensis (Bt). Yields for B...
متن کاملImpacts of Drought Stress and Planting Methods on Sweet Corn Yield and Water Use Efficiency
Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...
