title: Evaluation of a nematode bio-product Dbx-20% against root-knot nematode Meloidogyne incognita affecting grapevine under field conditions.
abstract: A field trial was conducted in El-Shourouk Farm, El-Beheira governorate, western Nile valley, Egypt to determine the effectiveness of the commercial bio-product Dbx 1003 20% containing the nematode-trapping fungus Dactylaria brochopaga against root-knot nematode Meloidogyne incognita infesting grapevine variety Superior. Its effects on plant growth criteria and yield production were also investigated. The fungus was introduced to soil by either of two ways. First: soil was drenched with spore suspension at the rate of 3 l/tree. Second: 1/2 kg of a vermiculite substrate, as a carrier of spores and mycelia was added around each tree both as single and twice application in autumn and spring. All treatments significantly reduced M. incognita J2 in soil and number of root galls compared with the untreated control. Significant yield increases have been observed with all treatments compared with the untreated control. Spores suspension twice applications gave the highest yield production.
