519BIOLOGICAL CONTROL OF RENIFORM NEMATODE ON SUNFLOWER THROUGH SOME BIOAGENTSThis study made to consider the effectiveness of commercial formulation of VAM fungus (Glomus mosseae), bacterial agent(Pseudomonas fluorescens) and antagonistic fungus(Trichoderma viride) against reniform nematode, Rotylenchulus reniformis on sunflower under greenhouse condition. Three bioagents each subsequently representing G. mosseae as soil application and P. fluorescens as seed treatment are held to improve the plant growth and yield of sunflower. As soil application, G. mosseae produced maximum reduction of nematode population in roots (65.1%) and soil (73.1%) which was on par with seed treatment of P. fluorescens. Significant numbers of eggs / egg mass also decreased in these treatments. The less effective R. reniformis managers were T. viride both as seed treatment and soil applicationhramezani@spnu.ac.irResearch5102014Bioagents,Biological control, Plant growth,Rotylenchulus reniformis,SunflowerHesamedin Ramezani,Mohammad Ali EbrahimiDepartment of Agriculture, Payame Noor University, PO Box. 193595-3697, Tehran, Iran,Department of Agriculture, Payame Noor University, PO Box. 193595-3697, Tehran, Iran
