RICE SEED TREATMENTS BY SOAKING IN WATER AND THREE PESTICIDES (CARBOSULFAN, BENOMYL, AND IMIDACLOPRID) TO CONTROL FOLIAR NEMATODE Aphelenchoides besseyi

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable dormancy seeds. This study aims to determine effects soaking seeds water and pesticides (carbosulfan, benomyl, imidacloprid) on mortality A. besseyi, seed viability, symptoms seedlings. specifically used infected with besseyi. Cold treatment (cwt) at 5-10˚C for 24 hours followed by hot (hwt) 52˚C 10 minutes caused 51.17% yet reduced viability. Soaking 25-30˚C hwt 57˚C could cause 48.67%, 39.18% 33.05% nematode mortality, respectively. Low all treatments (less than 60%) showed infection seedlings 21 days after planting. Seed dressing imidacloprid 5WP (2% weight) 47.25% whereas benomyl 50WP (0.2% carbosulfan 25ST only 27.61% 11.34%. Based two parameters (nematode viability), effective were imidacloprid.
