Technical Abstract: An Integrated Pest Management (IPM) program that used biorational/ biopesticide agents as components was tested. We need IPM cotton programs with low impacts on natural or exotic populations of beneficial arthropods in classic or augmented systems. Such IPM programs need to control all pests, with biorational agents replacing conventional chemistries and incorporate Insecticide Resistance Management (IRM) to reduce likely development of insecticide resistance. Biorational/ biopesticides 'fit' IRM since usually, they require different detoxification modes as they have widely different action modes. Deltapine upland cotton was planted and furrow irrigated. In 1997, we used DP 5415. Plots were 192.5 ft. in length and 6 rows across (40-in. rows) and plots were separated by 2 fallow rows and 8 ft. alleys. In 1998, we used NuCOTN 33B in plots 109 ft. in length and 12 rows across (40-in. rows) and plots were separated by 4 fallow rows and 20 ft. alleys. Ground applications were made. In 1997, applications were with 3 nozzles/row; 1 overhead, and 2 with swivel nozzles angled upward on drops; and applied at 80 psi and 30 gal./ac. In 1998, applications were made by ground with 5 nozzles/row; 1 overhead, and 2 swivel nozzles angled upward on a drop on each side of the row; and applied at 250 psi and 30 gal./ac.
