Reducing the use of chemical pesticides is closely related to the protection of the ecological environment and food safety. However, green prevention and control technologies such as biological pesticides are often met with the dilemma of "no success". The reporter discovers in bai muwa village of wang wu town of jiyuan city recently, the agricultural disease and insect pest prevention and control way here already changed quietly.

1, difficult technical complex habits difficult to change

Bai muwa village almost every family grow vegetables, the village of 1, 300 acres of farmland in 1, 000 acres of vegetables. Zhang shujie in the large plantation greenhouse to see a variety of colors of the sticky insect board can be seen everywhere.

Zhang shujie told reporters that in the past, all vegetables rely on chemical pesticides, biological pesticides no one.

Jiyuan baiyun industrial co., ltd. is a "leader" in the biological pesticide industry. Fang fenfen, technical director of the company, introduced that although biological pesticides have the advantages of safety and green, they are difficult to be promoted, especially for small farmers with decentralized operations.

Biological pesticides are slow to take effect, unlike chemical pesticides, which have an immediate effect. Biological pesticides are different from chemical pesticides in terms of control time and drug concentration, which requires pre-assessment of insect situation and drug application in advance for prevention, and the technology is relatively complex. In addition, the price of biological pesticides is also higher.

"In fact, these problems can be solved, the key is still habits, ideas." Vegetable farmer wang xiujun said.

2. Method demonstration drives "package" service

Farmers are the key factor to break through the "last mile" of green prevention and control. How to reverse their years of drug habit?

Jiyuan has solved the problem by setting up agricultural green prevention and control demonstration bases in recent years, and has built 9 demonstration bases so far. After the village became a demonstration base the year before last, farmers' habits gradually changed.

According to sun hongxia, head of the plant protection station in jiyuan, green prevention and control involves a variety of individual technologies.

At present, in addition to biological pesticides, natural enemies of insects, physical prevention and control, bumblebee pollination and other methods are also used in the demonstration area to weave a comprehensive prevention and control network.

Technical services and guidance are also important. Biological pesticides need to be used in advance. Plant protection stations should strengthen disease and insect monitoring and release "disease and insect information" in time to allow farmers to grasp the opportunity of drug use. A variety of measures to force, new ideas slowly infiltration, green prevention and control methods are gradually accepted by farmers.

3, the effect of green prevention and control signs

The benefits of green prevention and control, cypressokuwa vegetable farmers feel more and more deep.

Biological pesticides are slow, but better and more stable, while chemical pesticides are more susceptible to drug resistance. The price of biological pesticide is higher, but the action cycle is long, the use times is little, the total input is about the same as chemical pesticide.

In the past, villagers hit chemical pesticides, dizziness, skin itching and other symptoms, biological pesticides are not to worry about.

"Before merchants to receive vegetables, always worry about pesticide residues exceed the standard. Now the green prevention and control of vegetables in the village has become a gold signboard, merchants are very relieved. "Zhang shujie said.

Now, the baimuwa village basically realized the whole green prevention and control, in the selection of pest resistant varieties on the basis of the comprehensive implementation of biological, physical, mechanical control, disease reduction, drug use is also in decline.

According to sun hongxia, if the price of vegetables is raised through the certification of agricultural products, the market with high quality and good price will further promote the popularization of green prevention and control technology.
