Black Cutworm Control in Buckwheat, 1988

Insecticide and Acaricide Tests, 1990
Abstract An unusual migration of black cutworm into northern Minnesota led to a larval infestation that devastated buckwheat planted in former wild rice fields in the Washkish area. Plot size was 25 ft × 50 ft. Treatments were arranged in a randomized complete block design and replicated three times. Insecticides were applied with a hand

Black Cutworm Control in No-Till Corn, 1992

Insecticide and Acaricide Tests, 1993
Abstract Nine insecticide formulations were evaluated for control of black cutworm larvae. The test plot was planed in a continuous com field on the UK Spindletop Research Farm in Fayette Co., KY, on 1 May as a randomized block design with replicates. Individual plots consisted of 2 rows of no-till corn, 11 m long, with 96.5 row spacing.
