CONTROL OF PLANT-PARASITIC NEMATODES WITH 'NIMIN' AND SOME PLANT OILS BY BARE-ROOT DIP TREATMENT

M. Akhtar, I. Mahmood

Abstract


Bare-root dip treatment with 'Nimin' (contains-neem triterpenes) and some plant oils, viz., neem (Azadirachta indica), castor (Ricinus communis), rocket-salad (Eruca sativa) and mustard (Brassica juncea) showed significant inhibition of root-knot development caused by root-knot nematode Meloidogyne incognita, and population build-up of commonly occurring plant-parasitic nematodes on tomato (Lycopersicon esculentum). 'Nimin' was highly effective in reducing disease incidence. The damage caused by nematodes were recognized in terms of improved plant growth by the root-dip treatment. Root-knot development and nematode densities decreased and plant growth responses increased with increasing concentration of the test products.
