You can also spray the water 2 or 3 times repeatedly, and try to wash off the medicine on the surface of the plant. It is necessary to water sufficiently, increase the water absorption of the root system, increase the water content of corn cells, and reduce the content of the drug. But also pay attention to drainage, corn is afraid of waterlogging.
