What are the methods for reducing pesticide residues in agricultural production?

In agricultural production, pesticides are an indispensable helper. Whether it is weeding, killing insects or preventing and controlling diseases, they are mostly indispensable. Scientific use of pesticides can indeed improve the quality of agricultural production, but the issue of pesticide residues also needs attention. So how should pesticide residues in agricultural production be reduced? Let's take a look together.

1. Choose low-toxicity pesticides

There are many varieties of pesticides on the market, and their toxicity also varies. Many growers tend to choose highly toxic pesticides because the effect is more obvious and the speed is faster, but pesticide residues are also heavier. Therefore, in order to protect land resources and the environment, relevant national departments have explicitly banned the production of highly toxic pesticides. At present, most highly toxic pesticides on the market have been replaced by low-toxicity pesticides. With the upgrading of pesticides and advances in production technology, the effects of these low-toxicity pesticides are no worse than the previous highly toxic pesticides, so choosing low-toxicity pesticides is the most basic work for reducing pesticide residues.

2. Improve pesticide application techniques

In agricultural production, the main cause of pesticide residues is often improper pesticide application by growers. Pesticides should be applied scientifically and reasonably according to the characteristics of the pesticide itself. Take application equipment as an example. Different application equipment produces different droplet sizes when the liquid is sprayed. If the droplets are relatively large, the liquid cannot attach well to the leaf surface, crops cannot absorb the pesticide effect well, and most of the liquid will slide off or be blown away by the wind and enter the soil, very easily causing pesticide residues. Therefore, choosing application equipment with smaller droplets is key. It can not only improve pesticide efficacy but also reduce pesticide residues.

3. Combine with biological control

In agricultural production, in addition to using pesticides to prevent and control pests and diseases, other methods can also be used, such as biological control, which can save the amount of pesticide used and costs, thereby achieving the ultimate goal of reducing pesticide residues. For example, when controlling pests, natural enemies can be released for control. When controlling diseases, measures such as crop rotation and stubble reversal or deep plowing can reduce the occurrence of diseases, while weeds can be controlled by manual weeding or intertillage.
