Evaluation of Seed and At-Planting In-Furrow Insecticides on Cotton Grown in the Coastal Bend of Texas

Roy D. Parker and Raymond L. Huffman


 
ABSTRACT

Five tests were conducted to compare the effects of aldicarb applied in the seed furrow at-planting, acephate applied as a seed or planter box treatment and phorate applied as a seed treatment on insect pest populations and lint production. The two seed treatments were additionally evaluated in four tests. In all tests fruiting rate, lint yield, production earliness and fiber characteristics were measured. Thrips numbers were low at all test locations and differences were not observed between treatments. Thimet and Temik (1.0 lb ai/acre) treatments produced more early squares compared to the check. There was a trend for increased yield response from these two treatments. In the 9 tests involving the seed treatments, Thimet plots produced an average of 52 lb/acre more cotton compared to the check. This numerical yield response was observed at 7 of the 9 test locations.
