Abstract
The efficacy of avermectins B1 and B2 for control of M. incognita on tomato was studied in pots and field plots for 2 seasons. Avermectins were applied as granules and liquid in furrows or by low pressure drip irrigation systems, at rates ranging from 0.093-0.34 kg a.i.[active ingredient]/ha, as single or multiple applications. Levels of control comparable to those obtained by oxamyl and aldicarb at 3.36 kg a.i./ha were achieved by the avermectin with only 1/10 the volume of chemicals applied to the environment. Avermectin protection of the roots remained constant throughout the first 5 wk giving slightly longer protection than oxamyl or aldicarb.
