Abstract

Satisfactory reduction of sunflower head and seed damage by the sunflower moth, Homoeosoma electellum (Hulst), was afforded by carbofuran at both 1 and 2 Ib Al/acre, but seed weight per head was significantly increased only by the 2 Ib dosage. A misci-ble formulation of methyl parathion at 1 Ib Al/acre resulted in satisfactory reduction of seed damage and an increase in seed weight. An encapsulated formulation of this pesticide was not as satisfactory for control and did not significantly increase seed weight. Methomyl resulted in good reduction of damage, but did not significantly increase yields. Dipel (HD-1 strain of Bacillus thuringiensis Berliner var. kurstaki de Barjac and Lemille) was unsatisfactory for control. Methidathion at 1/2 Ib Al/acre and at two applications afforded very good sunflower moth control, reduction of seed damage, and significant increase in seed weight per head.
