EVALUATION OF SOIL INSECTICIDES FOR CONTROL OF SOUTHWESTERN CORN BORER AND CORN EARWORM ON FIELD CORN, 1999

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...

Multi-state trials of Bt sweet corn varieties for control of the corn earworm (Lepidoptera: Noctuidae).

Field tests in 2010-2011 were performed in New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 and Cry1Ab with their non-Bt isolines, with and without the use of foliar insecticides. The primary insect pest in all locations during the trial years was Heliocoverpa zea (Boddie), which is becoming the most serious insect pest of sweet corn...

Combined Impacts of Western Corn Rootworm Larval Feeding, European Corn Borer and Giant Foxtail on Field Corn

Corn rootworm (CRW) beetles exhibit a univoltine life cycle. Feral adults deposit their eggs into the soil of cornfields during July and August where they undergo diapause and overwinter. The following spring eggs hatch beginning in late May and continuing on into the middle part of June. Larvae of the new generation feed on developing corn roots. After reaching the third instar larvae pupate i...
