Abstract:
The root knot nematodes, belonging to the genus Meloidogyne, which have a wide host range, are the deadliest enemy of vegetable crops and a pest of crucial economic importance. These produce conspicuous galls on the roots and the infestations can be recognized easily in fields. It is very common and abundant in the sandy soils of Jaipur and adjoining areas. In Jaipur district, Sunflower an economically important vegetable crop was found infested with highly pathogenic Meloidogyne incognita. Histochemical tests were applied to localize lipids and lignins in the diseased and healthy root tissues. The metabolites viz. lipids and lignins were found more in galled roots as compared to healthy roots.
