First, water spray when spraying herbicide overdose clear, timely with water spray, remove leaf residue, reducing the concentration of the herbicide in Crops, wheat and timely irrigation facilitate transpiration, reduce injury. Second, when the fertilizer and water management measures are lighter, some leaves of the crop appear brown spots, and the heart leaves are not dead. The fertilizer and water management can be strengthened to compensate for the loss of water and fertilizer in some leaves, which can be recovered in a short time. Third, the application of antidote or the corresponding remedial agent ferrous sulfate can reduce the phytotoxicity of gram, which can make the residual simazine activity in the soil disappear. The phytotoxicity caused by the auxin type herbicide can be sprayed with gibberellin to reduce the phytotoxicity; the phytotoxicity caused by the contact herbicide can be sprayed with foliar fertilizer to promote the rapid recovery of the crop, thereby relatively reducing the phytotoxicity.
