Soak the fruit and vegetable seedlings in the bacterial solution prepared by Bacillus amyloliquefaciens with a concentration of 0.5 × 109 ~ 1.5 × 109 cfu/mL for 5 ~ 15 minutes before planting, and at the same time 18 ~ 22 days after planting the fruit and vegetable seedlings with a concentration of 0.5 × 109~1.5×109cfu/mL of Bacillus amyloliquefaciens by irrigating the roots once, and the dosage of 8~12L/hm2 was appropriate.

The field control effect test results showed that the control effect of Bacillus amyloliquefaciens on cucumber root rot was 56.29%, the control effect on tomato root rot was 66.75%, and the control effect on strawberry root rot was 74.17%.

The effect is remarkable.
