The management of such crops is more sophisticated and the number of laborers is higher. The contradiction between weed control is highlighted. However, in the daily use of herbicides, due to the inaccurate selection or improper application of herbicides, it often causes serious errors in production. Not only does it reduce or eliminate the crops in the season, but it also produces residual poisons to the crops.

When applying the above herbicides, the following points need attention: First, the selected herbicide species should be applied before seedling after seeding. The second is to apply the seedlings before transplanting. The third is that when the pesticide is applied, the soil moisture content must be sufficient, and the permeability will be better. When the temperature is low, it should be applied before and after noon, and when the temperature is high, it can be administered in the morning or in the afternoon.

After spraying with trifluralin, it is necessary to use toothed earthworms and soil in a timely manner to prevent the volatilization and reduce the control effect.
