Used herbicides are still weeds
Each herbicide has its own herbicide spectrum, and will not kill all weeds, but different wheat field grasses are not the same, for example, some wheat fields are mainly grassy weeds such as wild oats, and 6.9% are used. Aqueous agents can be controlled, and the water conditioner for horses is effective for the control of grassy weeds such as wild oats, but it has no effect on swine fever, and the swine fever in this wheat field will not be killed; Severe wheat fields occur in pigs, which can be controlled with 20% EC, because it is very effective against broadleaf weeds such as swine pupa and purslane, but it is also used against grass weeds and grass weeds. The sedge weed has no control effect, so grassy weeds such as wild oats in this area will not be killed.
It should be reminded that most varieties of wheat herbicides are currently required to be used before the jointing of wheat, and it is not appropriate to use drugs after the jointing of wheat, otherwise it is very easy to cause phytotoxicity. Considering that the application of herbicides may have an adverse effect on the jointed wheat, field treatment can be conducted with a method of picking and spraying only the areas where weeds are particularly abundant.
