1. The main control targets of Pymetrozine
Pymetrozine is mainly used to control piercing-sucking mouthparts pests, including rice planthoppers, brown planthoppers, gray planthoppers, white-backed planthoppers, black-tailed leafhoppers, green stink bugs, aphids, etc. These pests are important pests in agricultural production and have a serious impact on the growth and yield of crops. Pymetrozine can effectively control these pests and protect crops from damage.
2. Pymetrozine's insecticidal mechanism
The insecticidal mechanism of Pymetrozine is to achieve the control effect by interfering with the normal physiological activities of pests. It can be quickly absorbed by pests and transmitted to the whole body, causing paralysis and antifeedant reactions in pests, and eventually leading to the death of pests. In addition, Pymetrozine also has a long lasting effect and can continue to play a control role for a period of time.
3. Application effect of pymetrozine
In practical application, pymetrozine shows good control effect. It can not only effectively control the number of pests, but also reduce the degree of damage to crops caused by pests. At the same time, pymetrozine is easy to use and can be mixed with a variety of pesticides to improve the control effect. In addition, pymetrozine has little impact on the environment and meets the requirements of green agricultural development.
4. Precautions
Although pymetrozine has a good control effect, some issues still need to be paid attention to during use. First, when using it, the regulations on the use of pesticides should be followed, and it should be used according to the recommended dosage and method to avoid excessive use and pesticide damage. Secondly, pymetrozine may have a certain impact on some sensitive organisms such as aquatic organisms and birds, so it should be avoided to pollute the surrounding environment when using it. In addition, attention should be paid to the storage and transportation safety of pesticides to prevent fire and poisoning accidents.
In short, pymetrozine, as an important agricultural insecticide, has a significant effect on the control of piercing-sucking mouthparts pests. In actual application, we should choose appropriate pesticide varieties and usage methods according to the types of pests and their occurrence, to ensure the control effect while reducing the impact on the environment. At the same time, we should also pay attention to the safety and compliance of pesticide use to ensure the sustainable development of agricultural production.
