Mr. Truong Van Bien, Chairmanorange farmin Dong Trung hamlet, Dong Thanh commune (Yen Thanh) said that 3 years ago, through books and newspapers and learning about some models of using biological pesticides, he immediately applied them to his family's 5-hectare orange garden.

Specifically, with a 200-liter plastic barrel, he bought 10 kg of chili, 10 kg of garlic, 10 kg of ginger, 10 kg of galangal, ground all of them and poured them into 20 liters of molasses, 20 liters of white wine, 20 liters of vinegar, 10 liters of other preparations, and mixed them well in the plastic barrel. After 20 days of soaking and incubation, open the barrel lid and stir well before using. When using, mix 1 liter of biological solution with 40 liters of clean water to spray on the plants. With a 200-liter barrel of that solution, Mr. Bien can spray twice on the entire area of ​​5 hectares of oranges.

If using chemical pesticides, each spray costs 6 million VND, more worrying is that it pollutes the environment and affects the health of users and the community. While using this homemade biological pesticide from herbs, the cost is only 2 million VND/200 liter barrel, but can be sprayed twice, saving 60-70% of the cost of pest control, but the effect is as expected. After 3 years of use, it shows that with homemade biological pesticides, many types of harmful insects and bugs such as silkworms, stem borers, fruit borers, red spiders, green stink bugs, etc. can be prevented.

Mr. Nguyen Van Loan, owner of an orange garden in Nghia Dan district, said that buying chemical pesticides on the market is very difficult to determine the quality, so sometimes we have to spray them many times, which makes the cost high and affects human health. If we can make this biological pesticide, it will reduce costs and be safer.

However, homemade biological pesticides do not have specific properties for some pests, but mainly repel pests, especially insects. This is a new method but very practical, easy to do, effective, and reduces production costs. The industry encourages farmers to use it to protect the environment, ensure safety for users, but more importantly, to create a source ofclean agricultural products.
