Abstract
This work was conducted to study the effect of some ethanolic plant extracts i.e. lemon grass, Cymbopogon citratus, lantana, Lantana indica, camphor, Cinnamomum camphora, African marigold, Tagetes erecta, chrysanthemum , Chrysanthemum indicum and Acacia senegal at two concentrations ( 3 and 5%) on the control of wilt disease complex on tomato caused by root-knot nematode, Meloidogyne javanica and the fungus , Fusarium oxysporum f.sp lycopersici under greenhouse conditions at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shibin El-Kom, Egypt. The results showed that application of plant extracts significantly reduced the disease severity, disease incidence, population of M. javanica / 100 g soil and root gall index. Furthermore, all treatments enhanced plant growth. Extract of Cymbopogon citrates 5% gave the best results in the control of target pests, followed by Cinnamomum camphora 5%. On the other hand, Acacia sengegal extract 3% showed the least effects on the tested pests.
