Leafminer Control in Celery, 1985
Insecticide and Acaricide Tests, 1986Abstract Trials were conducted in a severely infested field of celery near Hudsonville MI (Ottawa Co.). Adult populations were in excess of 500 per 50 sweeps and flies were present on nearly every new leaf. Defoliation exceeded 80% (only new growth was free of mines). Plots were 3 rows by 25 ft, arranged linearly along the eastern border
