1. Insecticidal activity
As a natural plant active ingredient, capsaicin has significant insecticidal activity against a variety of pests. Its insecticidal mechanisms mainly include contact killing, stomach poison, antifeedant and repellent. When pests come into contact with pesticides containing capsaicin, their body surface or digestive system will be damaged, resulting in the death of the pests or stunted growth and development. At the same time, the special smell of capsaicin can also repel pests and keep them away from crops.
2. Biopesticide preparations
At present, a variety of capsaicin biopesticide preparations have been registered and applied in the market. For example, in the United States, capsaicin has powder and emulsion preparations registered; in China, there are mixed products such as 9% capsaicin·nicotine microemulsion and 1.2% avidin·capsaicin microemulsion registered. These preparations are widely used for pest control on fruit trees, vegetables and grain crops, and have the advantages of high efficiency, low toxicity and environmental protection.
3. Specific application scenarios
Fruit tree pest control: Capsaicin preparations can be used to control aphids, red spiders, borers and other pests on fruit trees. By spraying, capsaicin can quickly penetrate into the body of pests and destroy their physiological functions, thus achieving an insecticidal effect.
Vegetable pest control: In vegetable planting, capsaicin preparations can be used to control pests such as cabbage worms, diamondback moths, and aphids. These pests are sensitive to capsaicin, and the mortality rate of pests after application is high, and there is no adverse effect on the growth and quality of vegetables.
Grain crop pest control: On grain crops such as rice and wheat, capsaicin preparations can be used to control rice leafhoppers, aphids and other pests. By spraying or seed mixing, capsaicin can effectively control the population of pests and ensure the yield and quality of grain crops.
Advantages and prospects
Capsaicin has many advantages as a biological pesticide, such as high efficacy, long-lasting effect, and degradability. Compared with chemical synthetic pesticides, capsaicin pesticides are more environmentally friendly and safe, will not pollute the environment, and will not leave harmful substances in agricultural products. In addition, capsaicin has a wide range of sources and is renewable, with low production costs. Therefore, capsaicin has broad application prospects in the field of pesticides and is expected to become an important part of the future pesticide market.
In summary, capsaicin has significant insecticidal activity and broad application prospects in the field of pesticides. With the continuous advancement of technology and the continuous expansion of the market, capsaicin pesticides will provide a safer, more efficient and environmentally friendly pest control solution for agricultural production.
