Effect of extracts from three plant species on nematode Meloidogyne incognita (Kofoid and White) Chitwood
Nematodes of Meloidogyne
genus are a serious problem for tomato production in the province of Loja, Ecuador. Because of the negative side effects of chemical nematicides, to solve this problem it is necessary
look for alternatives. This work aimed to study the effect of ethanolic extracts from Lonchocarpus nicou
(Aubl.),Piscidia carthagenensis
Jacq. and Thevetia peruviana
(Pers.) K. Schum., in
Meloidogyne incognita
control, âinvitro
â and glasshouse conditions, on tomato plants. The extracts induced a significant mortality, â
in vitroâ, on
juveniles. This effect was related with the source and concentrations of the extracts. In tomato growing in
glasshouse, it was observed an appreciable reduction in the root gall index and in the nematode populations in
soil, related with the plant species and the concentration used, too
