Evaluation of a a Nematode-Encapsulating fungi complex for control of meloidogyne javanica on potato

Abstract

The efficacy of Nemout, a nematode-encapsulating fungi complex, was evaluated for control of M. javanica on potato in 3 greenhouse experiments. The efficacy of Nemout at 1.12, 2.24 or 3.36 kg/ha was evaluated on cv. Ajax in one experiment and comparisons with carbofuran (10 kg), fenamiphos (10 kg) and oxamyl (5 kg) were made on cv. Spunta in 2 other experiments. In all experiments Nemout significantly reduced the number of galls and eggs and increased tuber weight at the recommended rate of 1.12 kg, however, it was not as effective as the nematicides. The relative efficacy of Nemout to the average effect of all tested nematicides was 70% on galls and 74.9% on eggs.
