Doruwa (Parkia biglobosa) fruit husk and hyptis (Hyptis spicigera) leaves for controlling root-knot nematodes (Meloidogyne incognita) in tomato (Lycopersicon esculentum Mill C.V.)

摘要

A pot culture study to determine the efficacy of a mixture of dried and pulverized Parkia biglobosa fruit pulp and Hyptis spicigera leaves for controlling root-knot nematode in tomato ‘Roma King’ was carried out at Mubi, Adamawa State (Nigeria) between June to December 2004. Tomato plants inoculated with Meloidogyne incognita eggs and grown on media containing 10, 20, 30, 40, and 50 g of the mixture per pot (5 kg soil) had significantly (p< 0.05) lower root galls than the control. Taller shoots, more leaves, and greater number flowers and pods were also recorded in the 10 g soil treatment, implying its advantage over other levels.
