In the rice field, chloroquine acid and cyhalofop-butyl were sprayed for 5 days. The grass had turned yellow. The field had 2 days of water supply. Can it be topdressed with urea? Will it affect the weeding effect? Will weeds absorb fertilizer and will not survive? Normal fertilization should have no effect on the weeding effect. However, it was reported in production that the application of urea caused rejuvenation of older grasses that had been yellowed by herbicides. If field rice seedlings do not show obvious yellowing and yellowing, it is recommended to fertilize the weeds after their death.
