Stem Applications of Azodrin for Control of the Cotton Fleahopper12

Abstract

Azodrin® (3-hydroxy-N-methyl-cis-crotonamide dimethyl phosphate) was applied in a series of experiments to the stems of cotton plants with a recently developed rotary brush applicator for control of the cotton fleahopper, Psallus seriatus (Reuter). Effective control was obtained for 2 weeks with rates of Azodrin as low as 0.25 1b per acre. Results also demonstrated the feasibility of largescale field applications of Azodrin to the stems of cotton plants.
