With the advancement of agricultural technology, the variety of pesticides is complex and the situation of pesticides causing phytotoxicity is also very common. Then how to solve the phytotoxicity of pesticides? Scientific medicine is the key, and then Xiaobian will introduce you in detail.
As a special commodity to control pests such as pests and diseases in agricultural production, pesticides mainly include insecticides , fungicides, herbicides and plant growth regulators. After the application of pesticides, the annual yield loss of crops can be reduced by 30% to 40%, and economic losses can be recovered by 300 billion US dollars. Of course, the use of pesticides is indeed a double-edged sword, especially the abuse of pesticides in recent years. It does not pay attention to the safe application of pesticides, which makes the agricultural residues of agricultural products exceed the standard, causing pollution to the agricultural ecological environment, especially the pollution of rural water resources. Serious, and at the same time bring hidden dangers to people's health. So how do you reduce the negative effects of pesticides?
The first is to adopt a plant protection policy of “prevention first, comprehensive preventionâ€. First, before the occurrence of crop pests, preventive measures, the hazard control in the early stages. After the onset of the disease, chemical, physical, mechanical and other control measures are taken to reduce the use of chemical pesticides. To put it simply, just like people, first of all, strengthen physical exercise and reduce the incidence of disease, instead of waiting for a lot of medicine after the illness.
The second is to prohibit the use of high-toxic and high-residue pesticides. Develop new low-toxic, environmentally friendly new pesticides.
The third is to supervise the use of pesticides and to safely apply pesticides. In fact, the root cause of many agricultural products exceeding the standard is the abuse of pesticides, and pesticides are not applied strictly according to the interval between application. The safe interval of pesticide use refers to the number of days between the last application of pesticides and the harvest of agricultural new products, which can ensure that the agricultural residue content of agricultural products does not exceed the standard.
After the application of each pesticide, his safety interval is different. Therefore, the farmers' friends must observe the instructions of the pesticide when using the pesticide, and strictly follow the instructions in the application frequency and application amount. At the time of harvest, the number of days in the safety interval must be sufficient, so as not to cause the agricultural residue content of agricultural products to exceed the standard.
