Abstract
Results obtained from the laboratory assay showed that isolates of Trichoderma parasitized 60% eggs in average. Among them, two isolates T. harzianum Bi and T. virens VM1 with % 76.18 and %72.55 parasitism respectively showed more efficient comparing with the control. In green house, analysis of variance for the biocontrol potential of isolates, final population of nematode, fresh and dry root weight, fresh and dry leaves weight inoculated with isolates of Trichoderma was carried out. The results revealed a significant differences (P<0.05) between treatments and control according to Duncan,s Multiple Range Test. T. harzianum Bi and T. virens VM1 decreased population of nematodes, increased yield in autoclaved and field soils. In autoclaved soils two isolates T. harzianum Bi and T. virens VM1 decreased population of nematodes by %76.68 and %72.65 respectively comparing with the control. The Ragbi nematicide, T. harzianum Bi and T. virens VM1 decreased population of nematodes by %81.65, %75.15 and %72.85 respectively comparing with the control in field soils experiments.
