If you want to eat safer and healthier vegetables, what can you do to reduce pesticide residues when planting vegetables?

Pesticide residue refers to the residue of some pesticides in vegetables, fruits, fresh fruits and other ingredients, soil layers and water quality after using pesticides in agriculture, which will seriously endanger our physical and mental health immediately after taking them. With the progress of society and the improvement of life quality, everyone pays more attention to food hygiene and safety. Pesticide residues exist in vegetables and fruits for a long time, so how to reduce pesticide residues when planting fruits? Share it with everyone.

1. Reduce the demand for pesticides. In the production and manufacturing, we should vigorously carry out the prevention of agriculture and animal husbandry and the control of pests and diseases, and choose vegetable varieties with strong disease and drought resistance, which can reduce the application of pesticides and reduce pesticide residues. If it is very easy to produce pests and diseases under the continuous cropping standard, rotation can be used to reduce the accumulation of stem blight pathogens in soil environment. At the same time, you can also set up a sunshade net according to manpower to build a natural barrier to keep pests out of the net, thus preventing moths, reducing the demand for pesticides and reducing pesticide residues.

2. Effective selection of pesticides When selecting pesticides with low pesticide residues, we should first consider varieties with long pesticide residues and low pesticide residue limits. In the case that the selection of slightly toxic and low-residue pesticides can't douse pests and diseases, pesticides with moderate toxic side effects should be selected according to the types of vegetables to minimize the application of relatively highly toxic pesticides. At the same time, we should pay special attention not to increase the concentration and spraying frequency of pesticides at will.

3. Follow the safe interval of pesticides. The safe interval of pesticides refers to the time from the last spraying to the acquisition and application of food crops, and the time from the application of pesticides to the reduction of residues to the allowable residues. Because the growth and seasons of various vegetables are different, the dissolution and regression of various pesticides are also different, so the safe interval after using pesticides is also different. Therefore, it is very important to accurately grasp the safe interval of pesticides to reduce pesticide residues. The dosage strongly recommended in the label instructions should be strictly implemented, and the dosage and application times should not be increased at will to prevent the increase of pesticide residues.

4. There are some differences in drug resistance between different kinds of vegetables and during pregnancy. Long-term single application of the same drug will promote the development of drug resistance of pests and diseases. Therefore, growers should apply different pesticides alternately according to the toxic and side effects of pesticides and the occurrence law of pests and diseases, combined with the weather and the growth and development stages of vegetables and fruits, which is conducive to maintaining the control effect and service life of pesticides. Pesticides should be mixed, and multiple pesticides should not be mixed in a hurry. The pesticide residue after mixing should be less than that of single dose pesticide, and the control effect should be higher than that of single dose pesticide.
