We found that with the application of FYM @100Kg, neem cake @250g, nematode egg parasitic fungus Paecilomyces lilacinus @ 25g and curbofuran @60g per tree at early stage of nematode infestation is very effective.

Try to use Tatge sp flower plant by culturing them around guava trees cause they can secretion root exudation are harmful to nematode

Rather than use of chemical pesticides like carbofuran we sd also try biocontrol as intercropping with marigold or application of Azotobacter chroococcum HT54 to the

root zone of guava.

Nematode is the major problem not only in guava but also in other horticultural crops like papaya. Also in Vegetables n infield crops like wheat. We sd explore possibilities of biocontrol agents for control of nematodes.

Good suggestion by Dr. Pathak, in fact lot of work has already started on the aspect. Some of the publications are attached for the reference.

Nematode is the major problem not only in guava but also in other horticultural crops like citrus and grapes. Also in Vegetables like tomato. in citrus and grapes used carbofuran (furadan 3-G) @ 117g per plant. If we used neem khali @ 1Kg per plant then carbofuran (furadan 3-G) used @ 63 g per plant. In tomato used nematode registance variety Hisar Lalit (N.T.-8).

Any fumigant nematicide
