ABSTRACT The public services activity of vegetables root-knot nematodes control by Pasteuria penetrans. It is mainly to knowledge transfer of plant-parasitic nematode field diagnosis to the farmers. Because of their microscopic size and irregular field distribution, soil and root tissue samples are usually required to determine whether nematodes are causing poor crop growth or to determine the need for nematode management or control. Vegetables plantation such as chili pepper, tomatoes and egg-plant are main host of root-knot nematodes Meloidogyne spp. Typical symptoms expression in those vegetables, has been shown to be closely associated with root-knot nematode infection and gall formation. Plants exhibiting stunted or decline symptoms usually occur in patches. This information must then be coupled with some enverous of bacterial Pasteuria penetrans spores on a field and inside the root-knot nematodes body which usually found inside the root of host plants. The farmers were then train to formulate the root-powder which containing spores of Pasteuria penetrans as biocontrol agents. The trained farmers were expected could be anticipate the root-knot nematodes problem on their field and well known of various methods to diagnose, discourage and treat against plant parasitic nematodes in a least toxic, sustainable manner.
