root-lesion disease, which is caused by pratylenchus loosi , is one of the most important diseases currently impacting iran tea plantations. this disease causes great economic crop impacts. northern provinces, which supply much of iran’s tea production, have been especially hard impact by root-lesion disease.the purpose of this study was to biological control the nematodes as one of the main se...

in this research the effect of two species of arbuscular mycorrhizal fungi, glomus mosseae and glomus intraradices on root knot nematode, meloidogyne javanica was investigated and in different treatments the effects of this interaction on parameters of plant growth , nematode infection and mycorrhizal development were evaluated.shoot fresh and dry weight significantly increased in mycorrhizal t...

results significant differences were observed in the results of co-culture of nematodes larva and fungi after seven days. the most effective fungi against the nematodes larvae were cladosporium sp., trichoderma sp., fusarium equisetti, after seven days of incubation. materials and methods sheep feces were employed to provide the required third stage larvae source for the experiments. the nemato...

two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...

one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...

biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...
