Efficacy of abamectin seed treatment on Pratylenchus zeae , Meloidogyne incognita and Heterodera schachtii
Journal of Plant Diseases and Protection 116 (3), 124-128
Abstract: The aim of this study was to test the effect of various concentrations of abamectin on the reduction of early root penetration of three nematode species and on plant growth, when applied as a seed treatment on maize, cotton and sugar beet. The study revealed that penetration of Pratylenchus zeae was reduced more than 80% in maize at a dose of 1.0 mg a.i. seed^-1. The number of galls caused by Meloidogyne incognita race 3 in cotton was also reduced more than 80% with 0.1 mg a.i. seed. Penetration of Heterodera schachtii in sugar beets was reduced over 60% when seeds were treated at a concentration of 0.3 mg a.i^-1. seed. Root length, as well as shoot and root weights in all plants treated with abamectin were not significantly different from controls. Our investigation determined that using abamectin as a seed treatment is an effective way of reducing early root infestation of the three different nematodes at low concentrations in a variety of crops and does not negatively affect plant growth.
