How to prevent and control bacterial wilt and damping-off in rice seedlings at 10 days of raising seedlings?
For bacterial wilt and damping-off, prevention is more important than cure. Only when the rice seedlings are robust are they less likely to become infected, so field management should be strengthened. Pay attention to controlling the seedbed temperature; it should not be too high or too low. In particular, pay attention to the effect of the low temperatures of a late spring cold snap on the rice seedlings, and harden and root-restrict the seedlings at the appropriate time; the humidity during seedling raising should not be too high, as high humidity easily causes various diseases and...
