What are the advantages of biological pesticides? What should I pay attention to when using?

Pesticides are often used in rural areas, especially when farmers fertilize their fillings or fruit trees to kill insects. General pesticides will choose biological pesticides. Biological pesticides must have its advantages, and the advantages are still great. Just say that when using biological pesticides, we must pay attention to the following aspects. Here, Bian Xiao will talk to you.

I. Biological pesticides

Biological pesticide refers to the preparation that uses living organisms, such as fungi, bacteria, insects and viruses or their metabolites, such as pheromone auxin, to kill or inhibit agricultural pests. Biological pesticides, also known as natural pesticides, belong to non-chemical synthesis. Natural chemicals and organisms also have the functions of bactericidal pesticides and insecticidal pesticides. The collected pesticides include microorganisms such as pathogenic nematodes, bacteria and viruses, plant derivatives and insect pheromones.

Second, the advantages of biological pesticides

Biological pesticides have many advantages. Compared with chemical pesticides, there are essential differences in composition and route. Biological pesticides are safe to people and animals, and have little impact on the ecological environment, especially to induce pests, and the probability of illness is very low. Moreover, it can well inhibit the spread of toxins, and can also use agricultural and sideline products for production and processing to improve the yield. This is a major function of biological pesticides, but it also has some advantages, such as strong selectivity, low residue and so on.

Three. Preventive measures of biological pesticides

If biological pesticides want to be effective, we should first pay attention to the temperature of biological pesticides and grasp the control effect of spraying in time. Some farmers may leave pesticides for a long time after buying them, which is unacceptable. It is also necessary to master the humidity of pesticides, choose the spraying time, ensure that the control treatment is not exposed to strong light, give full play to the efficacy of drugs, and avoid being washed away by heavy rain. We must use drugs at the right time to ensure pest control.
