Matrine extract effects

Matrine is a plant-derived pesticide. It does not produce resistance to pests and has a good protective effect on natural enemies. It regulates the ecological balance of natural enemies and pests, reduces the number of pesticides used by farmers, and saves costs to a great extent. After spraying for 3 times, it can obviously improve plant growth and make the plant itself produce oxymatrine, which has a good effect on controlling cotton aphids, cotton thrips and cotton spider mites.

The single use cost of matrine pesticide is higher than that of conventional chemical pesticides, but in the long run, because it does not harm natural enemies, has a long duration, and does not produce resistance to pests, the later control will become easier and easier. It can be seen that it can overcome the shortcomings of conventional pesticides that are easy to produce resistance, frequent application, killing natural enemies and increasing manpower locomotives and other chemical defense costs, and meet the national target requirements for pesticide reduction and harm control.

Matrine usage and dosage

If the number of aphids is small, use 1000-1500 times the solution, and put 1.5-2.5 bottles of matrine per ton of water; if the number of aphids is large, follow 800-1000 For double liquid use, put 2-2.5 bottles of matrine per ton of water.

2. The spray amount of liquid medicine per mu is 50-60 kg. In view of the current rampant occurrence of cotton aphids, the spray amount per mu is better than 60 kg.

3. Stagger the spraying time at noon when the temperature is high, the spraying effect will be better in the morning and evening.

4. Add organic silicon synergist when preparing liquid medicine, the effect will be better.

5. There is no need to add any other pesticides to prevent and control aphids.
