The results of this experiment showed that the best effect was achieved in formula (b) (20 million units of streptomycin + 250% of WP powder and 120 kg of water) The effect is 6 6 .1%. The screening of different control lines is more ideal, the control efficiency is up to 66.1%, 58.0%, 50.6%, and 4.5% respectively, and the yield is 56%. 0 kg, followed by the prevention and control of lines. The control effects and yield were 1 9.8%, 49.7%, 53.5%, 15.3%, 34.04 kg and 41.8%, 41.2% and 5 4.76% , 1.09% and 1 8.40 kg, all of which increased compared with the control
