Use and efficacy of biphenthianidin

Bifenthianidin is a compound insecticide which is composed of bifenthrin and thianidin. Bifenthrin, a pyrethroid insecticide, is a nerve agent that interferes with normal nerve conduction by acting on sodium ion channels in the nervous system of pests, and eventually leads to paralysis and death of pests.

1. Composition of Biphenthianidin

Bifenthianidin is a compound insecticide which is composed of bifenthrin and thianidin. Bifenthrin, a pyrethroid insecticide, is a nerve agent that interferes with normal nerve conduction by acting on sodium ion channels in the nervous system of pests, and eventually leads to paralysis and death of pests. Clothianidin is a newly developed second-generation neonicotinoid insecticide, which also has neurotoxicity. By binding to the nicotinic acetylcholine receptors in the neural postsynapses of pests, it blocks the normal transmission of signals from the central nervous system of insects, thus causing insect paralysis and death. The combination of these two ingredients not only enhances the killing effect of the drug on pests, but also prolongs the holding period and helps to delay the emergence of resistance.

2. The mechanism of action

The mechanism of action of biphenthianidin is mainly reflected in its contact, stomach toxicity and internal absorption conductivity. After the application of the agent, it can quickly penetrate the exoskeleton of the pest, act on its nervous system, resulting in the pest poisoning paralysis, and death in a short time. At the same time, the drug can also be absorbed by the roots and leaves of the plant, and the transmission in the plant body up and down, and has a good control effect on the ground and underground pests. This internal absorption conductivity makes bifenthianidin particularly effective in soil treatment, protecting crops from underground pests for a long time.

3. Scope of application

The application of biphenthianidin is very wide, covering almost all crop pest control. In vegetable field, it can be widely used for pest control of cucumber, tomato, bean, pepper, eggplant and other crops. In terms of food crops, soybean, cotton, rice, potato, wheat, corn, peanut, sweet potato and other crops can benefit from the control effect. In addition, it can also be used for pest management of apple, pear, peach, cherry, strawberry, grape, mango, citrus and other fruit trees. Whether it is above-ground pests such as aphids, planthoppers, leafhoppers, thrips, etc., or underground pests such as root maggots, leek maggots, garlic maggots, grubs, ground tigers, etc., bifenthianidin can provide an effective solution.

4. Use effect

Bifenthianidin showed excellent quick-acting and persistent effects. Due to the addition of bifenthrin, the insecticidal activity is improved, so that the pest can be poisoned and paralyzed within a few minutes after the application of the agent, and the mortality rate of the pest can reach more than 90% within a day. The absorbance of clothianidin further prolongates the effective period of the agent, especially for soil treatment and control of underground pests, the effective period can be up to 90 days. This highly effective insecticidal effect and long-lasting protection ability make bifenthianide the first choice for farmers to control pests.

5. Precautions

When using biphenthianidin, the following points need to be noted:

1. Follow the instructions: apply the drug in strict accordance with the dosage and method of the instruction manual, and do not arbitrarily increase or decrease the dosage or change the application method.

2. Safe drug use: Pay attention to personal protection, avoid applying medicine in high temperature and high humidity environment, and prevent direct contact with skin and eyes. At the same time, it is necessary to clean the application equipment and protective supplies in time after application.

3. Alternate use: In order to delay the development of resistance, it is recommended to alternate the use of agents with different mechanisms of action.

4. Protect the environment: Since biphenthianidin is toxic to aquatic organisms such as fish and daphnia, it can not be directly spread in water bodies or near swamps. At the same time, pay attention to protecting bees and other beneficial organisms to avoid adverse effects on the ecological environment.

5. Reasonable management: While using bifenthianidin for pest control, it is also necessary to strengthen the conservation and management of crops and improve the resistance of crops to achieve sustainable development of agricultural production.
