Insecticides: For control of grape leafhopper

Abstract

Properly timed applications of Thiodan or Dibrom are currently effective for use in controlling the grape leafhopper. However, the past record of resistance problems that have developed with other insecticides indicates that it is only a question of time until the same difficulties occur with these materials. Saving these insecticides for emergency use, rather than preventive treatment, and further reliance on an integrated control program appears to offer the best solution.
