One of the major pests of the vegetables, root knot nematodes (Meloidogyne spp.) (Tylenchina: Meloidogynidae) (RKNs) can cause economic losses by forming knots on the host plant roots. RKNs are more prevalent in the greenhouse vegetable growing areas of the coastal regions. In this study, the effects of plant extracts from five different plants; Capsicum frutescens, Hyoscyamus niger (Solanaceae), Melia azedarach (Meliaceae), Xanthium strumarium and Achillea wilhelmsii (Asteraceae) were evaluated against RKNs. In the first studies; the effects of plant extracts (0.5, 1.0, 1.5, 3.0, 6.0 and 12.0 ...Daha fazlası
The gen us of roo t lesio n nematod es (RLN), Pratylench us, feeds an d reprodu ces in the roo t co rtex of man y plant s pecies. RLN was rep roduced on carrot cu lture by using a pu re cu lture. In vitro tes ts were carried out to determine the effects of plant extracts from three ind igenous plants: h enbane, Hyoscyamus niger; b ead-tree, Melia a zedarah and commo n cocklebu r, Xanth ium strumarium on P. tho rn ei (the major wh eat root-les ion nematode). The nematodes were expos ed for 12, 24, 48, 72 an d 96 hrs in three concen tratio ns of plant extracts. Th e effect of plant extracts was ...Daha fazlası
