Abstract/Contents:"Two experiments were conducted to determine timing and treatment rates for a microencapsulated formulation of azadirachtin applied to control of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), in turfgrass. In the first study, all treatments (2.5-7.50 Kg[AI]/ha) was applied to newly hatched larvae significantly diminished food consumption, reduced larval weight gain, and cut survival to the adult stage. Larval survival was linearly related to azadirachtin dosage at 11 d posttreatment. A significant linear relationship was found between azadirachtin dosage and feeding damage to the grass at 11 and 15 d posttreatment. In the second test, azadirachtin treatments applied either to small or to medium size larvae significantly reduced larval feeding damage. It might be possible to achieve higher rates of efficacy if the product were reformulated to make it disolve better in water."
