Comparison of In-Furrow Applications and Banded Treatments for Control of Meloidogyne arenaria in Peanuts and Soybeans

Abstract

Aldicarb, oxamyl, phenamiphos and carbofuran were applied at planting time in field experiments with Ransom soybeans and Florunner peanuts to study the effect of the method of application on their efficacy against Meloidogyne arenaria (Neal) Chitwood. Each nematicide was applied at rates of one and two pounds a.i./acre in the soybean tests and at one, two, and three pounds a.i./acre in the peanut experiments. Each nematicide rate in the soybean experiments was applied in-furrow, and in five and 14-inch bands followed by light incorporation; in the peanut experiments an additional seven-inch band application was included. Results indicated that banded applications were superior to in-furrow applications both for control of the nematode and in consequent yield response. Band widths of five or seven inches were adequate for optimal efficacy of the nematicides; no particular advantage was derived from the use of the 14-inch band when compared with the narrower bands of application.
