Effect of systemic chemicals and mustard interplanting on the control of Meloidogyne incognita in grapevine

T. G. Naganathan

Abstract


The root-knot nematode, Meloidogyne spp., occurs in horticultural crops, especially vegetables and fruits in Tamil Nadu. Meloidogyne incognita causes severe damage to grapevine, papaya and other fruit crops. Raski et al. (1965) found M. thamesi and M. incognita associated with grapevine and reported that M. incognita caused severe damage to the plant. The systemic nematicide aldicarb was found to reduce the root-knot nematode populations in vineyards and to increase the yield (Rajendran and Naganathan, 1978). The present study investigated the effect of granular systemic nematicides and interplanting of mustard on the control of M. incognita (Kofoid et White) Chitw. in grapevine cv. Muscat of Hamburg.
