Imidacloprid as a Seed Treatment for the control of Russian Wheat aphid (Diuraphis noxia) (Homopetra: Aphididae) on Barley

Abstract

Different rates of Imidacloprid as seed treatment for the control of Russian Wheat aphid (RWA) on barley were tested at Kotu and Chacha in northern Shewa during the 1995 and 1996 ’belg’ seasons. Combined analysis of variance over years and locations
showed significant (P < 0.5) effects of insecticide treatments and some of their interactions. At all rates tested, Imidacloprid protected the growing plants from RWA damage throughout the two seasons and increased yields. Hence, as a seed treatment Imidacloprid provided an environmentally safer approach to the control of RWA than is possible with sprays of broad-spectrum insecticides.
