Abstract:

In the small plot trial; diazinon. permethrin. malathion. methyl parathion and endosulfan at the manufacturer recommended rates and prayed 4 time starting at flowering significantly controlled the nymphs of the black leafhopper. Highest yield and net return were obtained in malathion-treated plants. Diazinon gave the lowest yield and net return but these were still higher than those of the unsprayed control.
