Development of safe chemical and biological formulations for control of nematodes in cucumber

Afield study was conducted to evaluate the effects of a chemical mixture, biological suspension and synthetic nematicide [oxamyl] on the fruit yield and development of a natural polyspecific microorganism community on cucumber plants. This community included the fungi Aspergillus niger, A. ochracious, A. terreus, Fusarium solani, Penicillium spp., Rhizoctonia solani, and Trichoderma spp.; the dominant bacteria Bacillus spp. and Pseudomonas spp. and the root-knot nematode Meloidogyne incognita. Changes in the density and structure of the community were presented and discussed. Plots treated with the mixture, consisted of red molasses [50 liter], milk [1 liter], smashed garlic cloves [5 kg] and water [45 liter], had the highest fruit yield and lowest M incognita population. Moreover, cucumber yield was significantly [P

Management of the root-knot nematode, meloidogyne javanicam on cucumber [cucumis sativus] with biological control agent

Two biological control agents, Nemaless [a commercial suspension of the bacterium Serratia marcescens; 1 x 10 [9] bacterial cells/ml] and Nemastop plus [a commercial suspension presumably of garlic, allium sativum, extract and the fungus Paeciiomyces lilacinus], were tried to determine their effects on cucumber growth parameters and Meloidogyne javanica development and reproduction. Both have significantly [P
