It belongs to the lupine alkaloid, a derivative of quinolisidine. It has specific and natural characteristics, and can be rapidly decomposed in nature, and the final product is carbon dioxide and water. Is a green, environmentally friendly insecticide.

Matrine is a natural plant pesticide, low toxicity to humans and animals, is a broad spectrum insecticide, with contact and stomach toxicity. It has good control effect on vegetable, apple tree, cotton and other crops such as rapeseed, aphids and red spider.

Plant insecticide

Matrine is a kind of plant insecticide with low toxicity. Once the pest touches, the nerve center is paralyzed, and then the protein of the insect body solidifies, the stomata of the insect body is blocked, and the insect suffocates to death. The insecticide has the effects of touch killing and stomach toxicity on pests, and has good control effect on rapeseed, aphids and red spiders on vegetables, apple trees, cotton and other crops.

Usage method

1. Prevention and treatment of cotton leaf mites: Before the first peak of cotton leaf mites in early June, when the red leaf rate of cotton seedlings reaches 7% to 14%, apply medicine, with 0.2% matrine water agent 250 to 350ml per mu and 40 to 50kg of water spray, spray evenly and thoughtfully.

2. Control of apple leaf mites: After the apple tree blossoms, the overwintering eggs of leaf mites start to hatch and control during the end of incubation, with 0.2% water agent 100-300 times liquid spray, spraying the whole leaf wet is appropriate.

3. Control of aphids: Apply medicine at the aphid occurrence stage, use 1% matrine alcohol solution 50 ~ 120ml or 0.3% water agent 50 ~ 65ml per mu, add 40 ~ 50kg of water, spray evenly on the back of the leaf and the leaf surface, and focus on the back of the leaf.

4. Prevention and control of rapeseed worms: about 7 days after the adult spawning peak and before the third age of larvae for prevention and control, with 1% alcohol solution 60 ~ 110ml and water 40 ~ 50kg per mu, or 0.3% water agent 50 ~ 70ml for water 40 ~ 50kg evenly spray, has a good control effect. The drug has poor control effect on 4 ~ 5 instar larvae.

5. Prevention and treatment of leek maggots: apply medicine in the early peak period of leek maggots, use 1.1% matrine powder 2 ~ 4kg per mu, add water 1000 ~ 2000kg root irrigation.

6. Control of underground pests: control of wheat tiger, grubs, golden needles, etc., with 1.1% powder 2 ~ 2.5kg per mu spreading, strip or seed dressing. Seeds are moistened with water, mixed with 1.1% powder 4 ~ 4.67kg for every 100kg of seeds, stacked for 2 ~ 4h and then sown.
