Matrine is a fungicide , which is often used to control fruit tree borer disease. However, there are many different opinions on the effect of controlling fruit tree borer disease. How about the effect of using matrine to control the heartworm?
Spraying 1% matrine 1000 times solution, spraying 4-6 days after the peak period of adult worms, can effectively control the occurrence and harm of P. sinensis. 1% pyrethrin • matrine microcapsule suspension agent 1000-1500 times liquid constant spray has good control effect on pear hibiscus, and the long-lasting effect period is up to about 10d.
Matrine insecticide sterilizing water agent application notes:
1. According to the severity of crop pests and diseases, the dilution factor should be determined according to the instructions for use of the drug label.
2. The most difficult to swallow in the process of application, because the agent has the strongest contact effect, it must be fully penetrated on both sides to achieve the desired effect.
3. When applying in the greenhouse, sometimes the temperature difference between the inside and outside of the shed is large, and the dosage is increased according to the water droplets in the shed.
4. Grasp the temperature. When spraying bio-pesticide, it must be controlled at an ideal temperature of 20 °C. According to the test data, the effect after spraying is better than that between 10-15 °C. The efficiency is 1-2 times higher.
5. The drug is a broad-spectrum insecticide-sterilized plant pesticide, and the foliar fertilizer component itself does not need to be added.
6. Do not mix with strong acid and strong alkaline pesticides when applying.
7. If you accidentally spray the liquid into your eyes, rinse immediately with plenty of water.
8. Keep this medicine out of the reach of children.

Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
