Pesticide is sprayed into crops or soil. After a period of time, most of it has disappeared due to light, natural degradation, rain, high temperature volatilization, microbial decomposition and plant metabolism, but there are traces of pesticide residues. Residual pesticides are not effective against diseases, insects and weeds, but they are harmful to humans and animals and beneficial organisms. In the case of the continuous use of pesticides and the use of pesticides, controlling pesticide residues and ensuring the safety and health of humans and animals has become a problem that needs to be solved. So how do you maximize the control of pesticide residues?
First, the rational use of pesticides
Depending on the nature of the pesticide should be, the occurrence of pests, the development of laws, dialectically pesticide, with minimal amounts strive for maximum control effect. Rational drug use in general should pay attention to the following questions:
1. Symptomatic medication, master the key period of medication and the most effective method of application;
2, pay attention to the concentration and dosage of the drug, and master the correct amount of application;
3. Improve the performance of pesticides, such as adding surfactants to improve the performance of the liquid;
4. Rationally mix pesticides.
Second, the safe use of pesticides
Should strictly abide by the "Safe Use of Pesticides", the provisions of "safe use of pesticides standards", prevention, comprehensive prevention and control. Highly toxic, high pesticide residues shall not be used for fruit, vegetables, herbs, tobacco and other crops, prohibits the use of pesticide poisoning fish, shrimp, frogs and other animals and birds and beneficial, in certain pesticide safety during the interval.
Third, the measures taken to avoid poisoning
In areas where pesticides are seriously polluted, crops that are easy to absorb pesticides are not planted for a certain period of time, and new varieties of disease-resistant and insect-resistant crops can be cultivated to reduce the application of pesticides.
Fourth, comprehensive prevention
Actively carry out agricultural control, biological control, and implement reasonable rotation and cropping of crops.
5. Actively develop high-efficiency, low-toxic, low-residue pesticide varieties, and ban the use of eliminated pesticide varieties.
6. Mastering the harvest period It is not allowed to harvest and utilize cultivated crops during the safe interval. Because of the different speeds of decomposition and disappearance of various agents, the growth trend and season of crops are different, so there are different safety intervals. The farther the crop is from the last spray, the better.
7. Decontamination treatment The pesticides remaining on the surface of crops and fruits and vegetables can be decontaminated. Pesticide residue contamination can also be reduced or eliminated by methods such as exposure and cleaning.
