Biological control of root-knot nematode Meloidogyne incognita infesting Eggplant by the nematode-trapping fungus Dactylaria brochopaga and the nematode egg parasitic fungus Verticilium chlamydosporium under field conditions

Abstract

Microbial control of root-knot nematode which infested Eggplant (Solanum melongena) by using the nematode-trapping fungus Dactylaria brochopaga & Verticilium chlamydosporium as a combined with yeast, molasses and vermiculate (F1+F2AVYM) is reported under field condition study. The results revealed that the highest percentage reduction in number of nematode larvae per 1kg soil was achieved when applying the fungi D. brochopaga & V. chlamydosporium together combined with yeast, molasses and vermiculate. Also the highest percentage reduction in number of root-galls per plant (93.1 %) was achieved by using the fungi D. brochopaga & V. chlamydosporium together combined with yeast, molasses and vermiculate. The data revealed that the weight of fruits per plant were significantly (P≤0.05 and/or P≤ 0.01) increased in all nematode-trapping fungus D. brochopaga treatments compared to the untreated check treatment
