ABSTRACT

TRIMAX^™ is a new insecticide from Bayer CropScience specifically for use on cotton that provides excellent control of major sucking/piercing insects in cotton. In addition, significant yield enhancement benefits have been observed even in situa-tions without economic target insect infestations. However, information is lacking on how TRIMAX^™ affects plant growth and thereby enhances yield. The current study was designed to understand plant response to foliar application of TRIMAX^™ with particular emphasis on the physiological and biochemical changes that occur and how these may effect the development of yield. Three sets of experiments were designed to supply information to quantify plant growth response to TRIMAX^™. The information should also permit us to determine, or at least formulate, an explanation of how TRIMAX^™ is affecting the growth and development of the cotton plant, and therefore enhancing yield.
