How to choose biological pesticides?

This depends on what crops are used, whether it is fruit trees or vegetables. Different crops choose different biological pesticides. Let's look at the fruit trees first. If this mite and some pests such as red spider and scarab are found on fruit trees, then we can choose a broad-spectrum insecticide, like this avermectin.

Avermectin is a biological pesticide widely used in pollution-free fruit production, which is accepted by most fruit farmers and can kill some occupational pests. Moreover, avermectin is not a pesticide with high residue and high toxicity. Avermectin is convenient and quick to use, and its efficacy is long-lasting. The control effect often plays a very thorough role, because avermectin is a long-acting pesticide, and its contact killing effect is very strong.

There are many kinds of biological pesticides on the market, and the propaganda slogans produced by various manufacturers are different. Keep your eyes open when choosing. To buy this biological pesticide, you must have the production date, certificate and shelf life, which meet the national standards for biological pesticides. Without this license, if the certificate fails to meet the national standards, we will not buy it.

Some bio-pesticide technologies are not up to standard, which will easily affect people and our livestock. We should pay attention to this. When we choose biological pesticides, we must choose those with low toxicity to people and animals, so that we won't worry too much when spraying. Because some people tend to raise chickens and ducks under fruit trees when planting fruit, which can play a role in clearing weeds, and if the fruit falls, it will be eaten by chickens and ducks, which is not easy to cause waste. Then, in this case, it is best to choose biological pesticides with low toxicity to people and animals. Of course, if you want to buy it, you should buy it from a big manufacturer, which is more reliable.
