Studies on the pathogenicity of Hoplolaimus indicus Sher to tomato and citrus plants

Abstract

A previous study (Gupta and Atwal, 1971) showed that tomato and some species of citrus were favourable hosts for the reproduction of Hoplolaimus indicus Sher, 1963. In the Indian Punjab large numbers of this nematode were found in the rhizosphere of plants in tomato fields and citrus orchards where yields were declining. The experiments discussed here investigated the effect of different population levels of H. indicus on these plants.
