Insecticides applied to improved wheatgrass pastures in northern New Mexico in the springs of 1976 and 1977 were all shown to reduce population of black grass bugs significantly (P<.01). Herbage yields were decreased as much as 50% on untreated crested wheatgrass plots in 1976. Plots treated with trichlorofon produced significantly (P<.05) higher herbage yields than the untreated plots. Malathion at rates as low as 354 g/ha of active ingredient were effective in controlling this pest.
