The results showed that the seedling protection rate of maize seed coating was as high as 83.7% and that of soybean seed dressing was 81.7%, respectively. There was a significant and significant difference between the two and the control respectively. For the control effect of underground pests, The results showed that there was a significant difference between the three seed treatments and the control, and the seed dressing also had a significant relationship with the control. Among them, soybean seed coating had the highest control effect, reaching 95.97%. Secondly, The effectiveness of the agent also reached 94.5 1%.
