Combined control of root-knot nematode and leaf-curl disease in tomato

Abstract

The white fly (Bemisia tabaci Gen.) transmitted leaf curl virus disease and root-knot nematodes, Meloidogyne incognita (Kofoid et White) Chitwood are major obstacles to the successful production of tomatoes in India. Damage caused by either of the pathogens is accentuated in the presence of the other (Swaroop and Goswami, 1969; Mayee et al., 1974). Some biocides have shown promise in controlling both pathogens (Sastry and Singh, 1971; Chhabra and Mahajan, 1974) and the results of further experiments with an extended range of biocides are reported here.
