Remote sensing technologies and site-specific management techniques were investigated for use in detection and control of cotton pests in the Mississippi Delta. Tarnished plant bugs occurred above threshold levels more frequently in vigorously growing cotton canopy than in slower growing canopy. Vigorous and slower growing canopy areas were visibly discernable with remotely sensed imagery. Prescription spray maps were generated from this imagery which reduced insecticide application requirements by 30-50%. Reddish cotton leaves that were severely infested by spider mites were discernable from healthy green and and yellow early mite-stressed leaves using a spectro-radiometer. Plant maturity and cutout parameters were used on a site-specific basis to reduce pesticide applications for late season arthropods by 30%.
