Book Description
Research was conducted in 2013 and 2014 to evaluate the influence of cotton (Gossypium hirsutum L.) insecticidal seed treatments, planting date, and preemergence herbicides on thrips (Frankliniella fusca) infestations in cotton. Studies included a preemergence and soil texture evaluation on cotton development, an evaluation of thrips infestations, cotton development and yield following application of various preemergence herbicides and insecticidal seed treatments, and a planting date evaluation where different cultivars where planted with exclusion or inclusion of preemergence herbicide use at four different planting dates to determine the effect on thrips infestations, cotton development, and yield.

Book Description
Cotton growth early in the season is affected by damaging levels of thrips in many production fields in Arkansas. During this time, insecticides used to control thrips and herbicides used to control weeds are often present at the same time on the cotton plant. This research explores how various combinations of herbicides and insecticides influence thrips numbers and cotton plant growth parameters early in the growing season. Pathways evaluated included interactions between preemergence herbicides and insecticide seed treatments and interactions between common tank-mixed foliar herbicides and selected foliar insecticides. No interactions in thrips control or plant growth were observed when using preemergence herbicides in combination with insecticide seed treatments. However, efficacy varied between chosen insecticide seed treatments and it may be concluded that in this experiment imidacloprid seed treatments exhibited greater control of thrips numbers than thiamethoxam seed treatments. There were isolated herbicide-insecticide interactions affecting plant growth parameters, but overall the co-application of tested herbicides and insecticides offer cotton producers the ability to integrate thrips and weed control without loss of thrips efficacy or negative impact on plant growth. Herbicide-insecticide interactions examined in this study suggested that pesticide combinations present on the cotton plant simultaneously, early in the season, have no significant interaction which may affect thrips control and early season cotton plant growth.

Book Description
Thrips are predictable and consistent pest of cotton and require management to preserve yield. Cotton seedling injury is influenced by thrips abundance and seedling growth rate. Planting dates affect both thrips abundance and seedling growth. Imidacloprid seed treatment consistently reduced thrips infestations and associated plant injury and significantly increased yield. However supplemental application of acephate was needed when thrips abundances were high and seedling growth was slow. Peaks in thrips abundance and seedling growth rate varies by year but in general risk of thrips injury is greatest on early planted cotton. Nozzle type did not influence the efficacy of thrips insecticides evaluated in this study. Application of insecticide using nozzles which deliver coarse droplets provided acceptable control of thrips on seedling cotton. Although seedling vigor can vary among variety, differences in varietal response to thrips management were not observed in this study.
