Pesticides from plants

The Hai Phong Center for Research and Application of Science and Technology has successfully studied pesticides from some plants containing active ingredients that inhibit pest hormonal system.

Raw materials for drug production are some plants selected, put into grinding and heat treatment, filter, concentrate, add preservatives then close to cans and bottles.

This line can produce from 500 - 1,000 liters / day, completely biological materials that do not harm humans and animals, do not pollute the environment.

The product can prevent many pests harmful to ornamental plants and clean vegetables.

Datura can be processed into biological pesticides.

Plant fluids used as pesticides are taken from plants with a strong odor, causing skin allergies to heat or rashes such as tobacco, bean seeds .

These plants contain toxins that have a strong, dark, spicy odor, such as leaves and pods of xoan trees, tobacco leaves, waterpipe tobacco, datura .

The method of harvesting plants used for pesticides also has its own way, depending on the type of plants and parts containing toxic substances of plants, there are plants containing toxins in roots (fish medicinal plants .), There are plants containing seeds in the seeds (na seeds, bean seeds .), containing plants containing toxins in leaves and stems (xoan, tobacco .).

Therefore, it is necessary to base on the above characteristics of plants that have measures to collect when the parts of plants have the highest toxin content to increase the effectiveness of pesticides.

Depending on the pest object on the forest of crops, we use different concentrations or different concentrations. The types of plants made from plants are very suitable to kill the pests of vegetables to create safe vegetables and fruits for consumers, in addition to the use of insecticides on other crops such as rice and corn. , beans, peanuts .
