Abstract:
The soybean cyst nematode (SCN) is one of the serious diseases in soybean production. With the current emphasis on environmental pollution and the demand for pollution-free agricultural products, nematodes biological control research received more attention. The effect of 12 parasitic fungal isolates filtrates which were made by Paecilomyces lilacinus, Fusarium spp Symbol`@@and Pochonia chlamydosporium was tested on SCN. It was investigated by investigated the difference of J2 distribution rate on WA.The methods of filtering paper and direct test were conducted in our laboratory.Both methods showed that SCN J2 were repelled by 12 parasitic fungal isolates filtrates in different degrees.The results of filtering paper method showed that the distribution rate of J2 with treatments of 12 parasitic fungal isolates filtrates was low on 0.1 cm area. The distribution rates of soybean cyst nematode juvenile(J2) with the treatment of F9-3，V2，F5 and V1 isolates filtrates were 17.3%,17.3%,18.0% and 18.3% in the 0.1 cm area, respectively. It was significantly lower than control in water and root diffusate by 26.0% and 32.3%(P＜0.05). The same result was indicated in direct test. The distribution rates of soybean cyst nematode Juvenile(J2) were between 18.0%-31.3%,in 0.1 cm area with the treatments of soybean root dipped with 12 parasitic fungal fermentation filtrates.It was significantly lower than the control. It was proved that soybean cyst nematode juveniles (J2) were repelled by 12 parasitic fungal fermentation filtrates.
