Six systemic insecticides, Azodrin® (3-hydroxy-N-methyl-cis- crotonamide dimethyl phosphate), Baygon® (o-iso-propoxyphenyl methylcarbamate), disulfoton, NIA 10242 (2 ,3-dihydro-2 ,2- dimethyl-7-benzofuranyl methylcarbamate) phorate, UC 21149 (Temik®) (2-methyl-2- (methylthio) propionaldehyde o- (methylcarbamoyl) oxime), were tested in 1965 and 1966 at Portageville, Missouri, to evaluate the possibility of reducing the incidence of corn virus disease symptoms through the control of disease vectors, and to study their effects on the southwestern corn borer, Zeadiatraea grandiosella (Dyar). Five systemic insecticides were tested in 1965 on 2 hybrids susceptible to and 2 resistant to corn virus disease. The systemic insecticides were placed in the furrow with the seed at planting. NIA 10242 at 2.0 and 3.0 lb technical material per acre gave promising results. Tests with 4 systemic insecticides and 1 hybrid susceptible to corn virus disease in 1966 gave similar results. Corn virus disease symptoms were present each year in all treated plots, but the severity and incidence of infection were decreased, especially by NIA 10242. These results reflect the possibility that a portion of the virus disease syndrome were present in southern Missouri is due to infections by a persistent virus transmitted by 1 or more vectors. The most effective control of southwestern corn borer was obtained by NIA 10242.
