Effects of cropping systems and a nematocide on root knot nematodes and quality and yield of tomato transplants
Johnson, A.W.; Campbell, G.M., 1977: Effects of cropping systems and a nematocide on root knot nematodes and quality and yield of tomato transplants. Journal of the American Society for Horticultural Science 102(6): 819-821
Millet, milo, soybean, crotalaria and Norman pigeon pea [Pennisetum americanum, Sorghum vulgare, Glycine max, Crotalaria spectabilis and Cajanus cajan, respectively] were used in conjunction with clean fallow and a nematocide (fensulfothion) for managing root-knot nematode [Meloidogyne incognita] populations in tomato (Lycopersicon esculentum Mill.) transplant production. Clean fallow was most effective in suppressing numbers of nematodes. After 2 yr, numbers of nematodes increased to damaging levels and fallow was no longer effective for complete control even when used in conjunction with fensulfothion. After 4 yr none of the crops used as summer cover crops alone or in conjunction with fensulfothion reduced numbers of root-knot nematodes in harvested tomato transplants sufficiently to meet Georgia [USA] regulations.Other references
