EVALUATION OF FIVE NEMATICIDES AS SEED TREATMENT FOR THE CONTROL OF MELOIDOGYNE INCOGNITA INFECTING GREEN GRAM, VIGNA RADIATA

Abstract

Carbofuran, diazinon, phorate, prophos and sebuphos, each at the rate of 0.5, 1 and 2 per cent a.i. (W/W) were tested as seed treatments for the control of Meloidogyne incognita infecting green gram under field condition. Each of the chemicals was effective in decreasing nematode numbers and root-knot development, with consequent increase in plant growth. The best result was obtained with carbofuran at 2 per cent a.i.
