How to reduce Pesticide residues in Agricultural production

Pesticides are rare helpers in agricultural production, whether it is weeding, insecticidal or disease control, most of them are inseparable from it. Scientific use of pesticides can indeed improve the quality of agricultural production, but the problem of pesticide residues also needs attention. So how to reduce pesticide residues in agricultural production? Let's take a look.

1. Choose low toxic pesticides

There are many kinds of pesticides on the market, and the toxicity is also high or low. Many growers often like to choose highly toxic pesticides, which has obvious effect and fast humidity, but the pesticide residues are also heavy. Therefore, in order to maintain the land resources and environment, the relevant state departments have explicitly banned the production of highly toxic pesticides. At present, most of the highly toxic pesticides on the market have been replaced by low toxic pesticides. With the upgrading of pesticides and the adoption of production technology, the effect of these low-toxic pesticides is not worse than the previous high-toxic pesticides, so the selection of low-toxic pesticides is the most basic work to reduce pesticide residues.

2. Improve the technology of pesticide application.

The main cause of pesticide residues in agricultural production is also caused by improper application of pesticides by growers, which should be combined with the characteristics of pesticides. Take the pesticide application equipment, for example, different application equipment, the droplet size of the liquid spray is also different, if the fog drop is large, the liquid can not be well attached to the leaf surface, the crops can not absorb the efficacy well, most of the solution will be slipped or blown off by the wind, into the soil, it is very easy to cause pesticide residues. Therefore, the selection of application equipment with smaller fog droplets is the key, which can not only improve the efficacy, but also reduce pesticide residues.

3. Combine with biological control

In agricultural production, in addition to the use of pesticides to control plants, other methods can also be used, such as biological control, which can save drug consumption and cost, so as to achieve the ultimate goal of reducing pesticide residues. For example, in pest control, natural enemies can be released for disease control, in disease control, crop rotation or deep ploughing and other measures can be used to reduce the occurrence of diseases, while weeds can be carried out by artificial weeding or intertillage.

The above is an introduction to the methods of reducing pesticide residues in agricultural production. I hope it can help you. If you want to know more about it, please follow me.
