Comparison of Methods of Application with Two Systemic Nematicides for Control of Root-Knot Nematodes in Peanut and Soybean

摘要

Aldicarb (Temik(?) 15G) and phenamiphos (Nemacur(?) 15G) were applied at planting time in banded, in-furrow, and combination banded + in-furrow treatments to control Meloidogyne arenaria (Neal) Chitwood in peanut (Arachis hypogaea L.) and M. incognita (Kofoid & White) Chitwood in soybean (Glycine Max Merr.). The banded treatments were applied at rates of 1.1, 2.2, 3.4, and 4.4 kg a.i./ha and the in-furrow treatments at rates of 1.1 and 2.2 kg a.i./ha. Combination treatments were at rates of 1 1 and 2.2 kg a.i./ha for both the banded and the in-furrow components. Results indicated that simple band treatments provided equal or better nematode control and yield increases than the simple in-furrow treatments in both peanut and soybean. The combination treatments did not result in any significant advantage over the simple banded treatments at equivalent rates for nematode control or yield response.
