Phorate was applied at 1 lb active ingredient per acre as a broadcast spray to the surface of the soil of a notillage corn field for control of slugs, primarily the gray garden slug, Deroceras reticulalum (Muller). The effectiveness of phorate was influenced by date of application and number of applications. Although 1 application of phorate greatly reduced slug populations, maximum population reductions would be obtained from 2 properly timed applications. The 1st treatment should be applied when peak slug activity is observed and/or plant damage is sufficient to warrant treatment. The 2nd phorate treatment should be applied 15-20 days later or when slug populations have reached economic levels.
