Abstrakt: During 2003-2005 selected cotton varieties possessing the WideStrike™ trait (plant incorporated protectant expressing Cry 1F and Cry 1Ac insecticidal proteins) were evaluated for suppression of variable Helicoverpa zea (Boddie) infestations in greenhouse and field tests. Good suppression of H. zea damage to plant terminals and fruiting structures occurred under intense and moderate infestations with or without use of insecticide (Karate® @ 0.03 lbs ai/acre + Tracer® @ 0.062 lbs ai/acre) and was similar to cotton varieties expressing Bollgard I® and Bollgard II® traits. Insect control by WideStrike™ varieties tolerant to glyphosate were not affected by use of the herbicide on the cotton. [ABSTRACT FROM AUTHOR]
