Adjusting the root-knot nematode M. incognita population using abiotic or biotic factors such as animal manure, essential oils, colored plastic mulches and microbial agents i.e bacteria, fungi singly or mixed with synthetic nematicide has earned much more benefits in excreting nematode development and suppressing host damage of many host crops. However, results of the present work initiate the novel phenomenon in diminishing plant parasitic nematodes such as the root-knot nematode, M. incognita (the target of this work) and ameliorating plant growth criteria of such Malvaceae crops as hosts...

Peanut, Arachis hypogaea L. is one of the most important legume and oil crops for human consumption and animal feeding.Several plant parasitic nematodes were recorded as pathogens of peanut plants all over the world. A world survey of nematologists, annual losses caused by all nematodes to peanut were approximately 12 %.The root-knot nematode, Meloidogyne javanica is the major nematode species that parasitize peanuts in Egypt. Moreover, it is well known that nematicides are costly and potentially harmful to the environment.Therefore, the present investigation was carried out to...
