Precautions for Pesticide Use and Key Points for Safe Application
In vegetable cultivation and production, because some vegetables have very poor disease resistance, pesticides are needed for pest and disease control. However, many growers have many misunderstandings when using pesticides, which not only leads to poor sterilization and insecticidal effects, but also affects the growth of vegetables. Therefore, we need to pay much attention when using pesticides. So let's take a look together with the editor at the precautions during pesticide use!
1. Do not use pesticides blindly
Some growers, especially novice vegetable farmers, when choosing pesticides, do not consider the properties of the pesticide or the category of pests and diseases at all, and thus use them blindly, leading to results that are counterproductive. When we choose pesticides for pest and disease control, we must first fully understand the symptoms and transmission habits of various diseases. Only by treating the right cause can we effectively improve the control effect of pesticides.
2. Do not mix pesticides indiscriminately
When using pesticides, because the ingredients of some pesticides have auxiliary effects on each other, they can be mixed together, which has the effect of saving time and effort. However, because some people do not fully understand the properties of pesticides, they casually mix insecticides and fungicides. This leads to extremely high concentrations of some pesticides, causing pesticide damage to some plants. Moreover, some pesticides will also undergo chemical reactions with each other. Although they will not cause harm to the plants, they will also reduce the pesticide effect. Therefore, be sure not to mix pesticides casually. You should consult experts, or conduct a small-area trial before mixing them on a full scale.
3. Do not excessively pursue speed of effect
When many growers choose pesticides, most of them take speed of effect as the primary principle. They think that the faster the effect, the better, and that the quality will not be too poor. This causes some pesticides that actually have good effects but act relatively slowly to be unrecognized by everyone. Therefore, when growing vegetables, everyone should still choose pesticides according to the actual situation, and they must match the growth habits of the crops so that the control effect can reach its best.
4. Do not blindly seek new products
Now society is developing faster and faster, and various new pesticides are emerging one after another. This has led some vegetable farmers to have the illusion that pesticides with new ingredients have good control effects, while pesticides with old ingredients have poor control effects. This has allowed some unscrupulous merchants to exploit the gap by changing the packaging of previous old pesticides, and after “giving them a makeover”, putting them back on the market to deceive farmers. Therefore, everyone must pay attention not to blindly seek new products. You must ensure that you understand the pharmacology of pesticides and the symptoms of pests and diseases, and carry out control work according to the actual situation to ensure the control effect.
The above is a brief introduction to the precautions during pesticide use. When using pesticides, we should focus on prevention, and may emphasize treatment over prevention. Strengthening prevention work is the key to controlling pests and diseases. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
