A FIELD TRIAL TO USE THE NEMATODE-TRAPPING FUNGUS ARTHROBOTRYSDACTYLOIDESTO CONTROL THE ROOT-KNOT NEMATODE MELOIDOGYNE INCOGNITA INFESTING BEAN PLANTS

摘要

Microbial control of root-knot nematodes by using the nematode-trapping fungus Arthrobotrys dacty-loides alone or combined with yeast, molasses and vermiculate is reported under field condition study. The results revealed that the highest percentage reduction in number of nematode larvae per 1 kg soil was achieved when applying the fungus A. dactyloides with yeast, molasses and vermiculate. Also the highest percentage reduction in number of root-galls per plant (94.1%) was achieved by using the fungus A dactyloides with yeast, molasses and vermiculate. The data revealed that the weight of fruits per bean plant were significantly (P<0.05 and/or P<0.01) increased in all nematode-trapping fungus A. dactyloides treatments compared to the untreated checktreatment.
