First, pay attention to the selectivity, specificity, and timeliness of chemical herbicides. Do not misuse or abuse them.
Second, strictly control the limited dose, according to soil quality, farmland microclimate, according to the dose range, concentration use.
Third, a reasonable mix of medication. When more than two types of herbicides are used together, it is necessary to strictly control the mixing ratio, application time, and spraying techniques. There should be no chemical reaction and other side effects between the agents to ensure that the herbicides enhance efficiency and avoid phytotoxicity, thus ensuring the safety of the medicinal materials.
Fourth, pay attention to pesticide isolation and wind direction, fog, so as not to cause damage to other crops near the farmland.
Fifth, pay attention to the impact of environmental conditions on herbicides, temperature, light, moisture, soil type, organic matter content, cultivation and soil preparation and other factors will affect the herbicide weeding effect.
