The best period of herbicide treatment for corn is 3-5 leaves of maize seedlings and 2-4 leaves of weeds. The best time to use herbicides is after 6 p.m. Because corn needs 2-6 hours of absorption process after spraying herbicide, if spraying during the day, the temperature is too high and the light is too strong, the solution will volatilize quickly, affecting the weeding effect.

The herbicide was selected in the period of 3-5 leaves of maize seedlings and 2-4 leaves of weeds, because the application period was too late, the resistance to weeds was enhanced, and the herbicidal effect was affected, especially the mixture of Yunongle and 2my4MuthD butyl ester could not be applied after the 5-leaf stage of corn.
