An IPM program consisting of Decis® (deltamethrin), Phaser® (endosulfan) and Ovasyn® (amitraz) was compared to a standard program consisting of methyl parathion, Karate® (lambda-cyhalothrin) and Larvin® (thiodicarb). The study was conducted in 1995, 1996, 1997, and 1998. The IPM program outperformed the standard program which was reflected in 1) reduced bollworm/tobacco budworm (Helicoverpa zea/Heliothis virecens), boll weevil (Anthonomus grandis) and spider mites (Tetranychus spp.), 2) higher beneficial populations, 3) increased yield and 4) improved economic benefits. The benefit was attributable to the use of Phaser® which was much less harsh on beneficials than methyl parathion and the careful selection of products and rates accompanied with the use of local thresholds. The benefit was seen in both conventional and BT cotton.
