Efficacy of selected insecticides for the control of cotton aphid in the Northern Texas Blacklands

摘要

Provado, Leverage, and Furadan were compared for efficacy in both 1999 and 2000. Calypso was added to the test in 2000. Calypso was shown to be as efficacious as Furadan in controlling cotton aphid in the Northern Texas Blacklands in 2000. Provado and Leverage were somewhat less efficacious than Furadan in 2000, but performed as well as Furadan in 1999.
