Maximum control of pesticide residues

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 pests and weeds, but they can cause harm to humans and animals and beneficial organisms. So how do you maximize the control of pesticide residues?

1. Rational use of pesticides

According to the nature of pesticides, the occurrence and development of pests and diseases, pesticides should be applied in a dialectical manner, and strive to obtain the maximum control effect with the least amount. In general, the following issues should be noted in the rational use of drugs.

1.1 Symptomatic medication, according to the occurrence characteristics of pests and diseases, select the most effective pesticide products. 1.2 Grasp the use of pesticides in the most critical period and weak links of pests and diseases.

1.3 Strictly control the dosage, spray according to the dosage specified in the pesticide label, and require the agent to be evenly and thoroughly sprayed on me to avoid heavy spray and leak spray.

1.4 Improve the performance of pesticides, such as the addition of surfactants to improve the performance of the liquid.

1.5 Rational mixing of pesticides. When using pesticides, it is necessary to rotate the drugs alternately, mix them properly, and mix them to prevent the use of one pesticide for a long time.

2. Safe use of pesticides

It is necessary to strictly follow the requirements of the "Safety Regulations for the Use of Pesticides" and the "Guidelines for the Rational Use of Pesticides", mainly for prevention and comprehensive prevention and treatment. It is strictly forbidden to use high-toxic and high-residue pesticides on crops such as fruit trees, vegetables, Chinese herbal medicines and tobacco. It must be carried out at a safe interval during application.

3. Take anti-drug measures

In plots that are heavily polluted by pesticides, 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.

4, comprehensive prevention

Actively carry out agricultural control, biological control, and implement reasonable rotation and cropping of crops.

5, master the harvest period

It is not allowed to harvest and utilize cultivated crops during the safety interval. The speed of various pesticides is different due to their decomposition and disappearance, and the growth trend and season of the crops are different. Therefore, there are different safety intervals, and the crops are sprayed at the end of the harvest. The longer the time, the better.

6, carry out decontamination treatment

Pesticides that remain on the surface of crops, fruits and vegetables can be decontaminated, such as by exposure, cleaning, etc., to reduce or eliminate pesticide residue pollution.

7. Increase pesticide supervision and management

To control the residues of agricultural products, it is necessary to strengthen the management of the pesticide market, combat the illegal production of high-toxic pesticides, and the use of highly toxic pesticides and pesticides in the compound preparations. We will increase the monitoring of agricultural products, improve the means of detecting agricultural products, and strictly control the sales of agricultural products with excessive pesticide residues, so as to achieve the purpose of controlling pesticide residues in agricultural products.

8. Strengthen publicity and education

Due to the lack of laws and regulations on pesticides and the scientific knowledge about the toxicity of pesticides, farmers must improve their own quality, foster their sense of responsibility, and create an atmosphere that controls the environment polluted by pesticide residues through publicity, education, training and dissemination of relevant materials.
