Abstract:
In this experiment, the effects of biocontrol agents Helisu on SCN and Root Rot were studied by seed coating, foliar spraying and Nano-Se-rich coating. The results showed that the different treatments of biocontrol agents Helisu could promote the growth of soybean seedlings, the physiological activity, chlorophyll, protein and total soluble sugar content of soybean seedlings. The seed coating treatments increased 1.53, 0.83 and 0.82 mg·g-1 compared with the contrast.The Nano-Se-rich coating treatments increased 1.48, 0.69 and 0.26 mg·g-1, respectively. The foliar spraying treatments increased 1.14, 0.37 and 0.36 mg·g-1, respectively. All tested treatments had a certain control effect on SCN, the effect of seed coating treatment was greater than the Nano-Se-rich coating treatment, and than the foliar application. The average control effect of the four stages of seed coating was 54.77%, 33.43% and 25.95%, respectively.
