A comparative study between some biocontrol agents and the nematicide furfural on growth of tomato plants and pathogenesis of meloidogyne javanica under green-house condition

Abstract

An experiment was conducted to study the effect of three fungal biocontrol agents along with G.mosseae and nematicide furfural against root knot nematode Meloidogyne javanica infecting tomato plants(Lycopersicon esculentum) under greenhouse condition. Bioagents are Paecilomyces lilacinus, Trichoderma harzianum , T. viride and mycorrhizal fungus Glomus mosseae which were compared with the nematicide furfural . The furfural compound was the best treatment in promoting plant growth and reduction the number of root galls/plant . The result showed that the T. harzianum was the best biocontrol agent in increasing shoot length and root length 16.2 % , 26.1% respectively .The P. lilacinus was the best biocontrol agent in reduction root galling (57.53%). Combination of biocotrol agents with G. mosseae and furfural was the least effective treatment in promoting plant growth and the reduction of root galling was 31.43%.
