Abstract:
Fermentation liquor of actinomycetes strain Snea253 and other microbial strains were used to prepare the biological seed coating, then we treated soybean seeds by these seed coating and sew them in experimental areas in Liaoning and Heilongjiang provinces. We counted the cysts outside the soybean roots and in the soil around the roots, and different stages soybean cyst nematodes inside the roots from 30 to 35 days after seeding. The results showed that the biological seed coating A(mixed biocontrol microorganisms Snea253+Sneb207+ elements+adjuvants) had significantly higher control effect than the no coated control and commodity seed coating control in the test fields. The biological seed coating B (mixed biocontrol microorganisms Snea253+Sneb482+Snef1024+elements+adjuvants) and the biological seed coating C (Snea253+ elements+adjuvants) were as good as the commodity soybean seed coating. Biocontrol seed coating could not only promote soybean growth and development, but also effectively suppress soybean cyst nematode numbers around soybean roots and increase soybean yield. They are safe and reliable, especially biological seed coating A can increase production and inhibit soybean cyst nematode numbers significantly.
