Today is the full festival of the twenty-four solar terms, which means that it gradually turns into midsummer and the weather is getting hotter. This season is just the time of the spread of pests such as red spiders and locusts. And its pest performance not only occurs in agricultural production, but also in the family's horticulture or vegetable garden, and the impact of these pests on the plant must be said. So what preventive measures can be solved? The following small series of Huinong.com introduces several prevention and control measures for everyone.
1, cigarette water
Cigarettes have a special smell of tobacco. For red spiders and mites, they are difficult to adapt to such an environment. Therefore, we can use the soaked overnight cigarette water to spray the flowers we plant. Generally, it can be sprayed two or three times. A lot better. However, this method can only play a certain preventive role, and can not completely kill such pests such as spider mites and mites, which can be said to be palliative. Fortunately, the deworming effect of cigarette water is obvious, at least reducing the threat of insect pests, and ensuring that the plants are green and non-toxic.
2, destroying the growth environment of pests
The commonly used method is to spray the flowers with soda water. The soda water is also a sodium bicarbonate solution, which is weakly alkaline in water. After spraying onto the leaves of the plants, the pests are unable to adapt to this alkaline growth environment, and it is difficult to continue to survive like aphids, red spider worms and eggs. Of course, vinegar can also be sprayed with flowers after 200-fold dilution. This method is similar to soda, except that the environment is kept in an acidic environment. However, although such alkaline solutions and acidic solutions are more effective in killing insects, they still have certain effects on the plants, but they do not kill these plants.
3, drug prevention
Aphids: Commonly used anti-bacterial agents are imidacloprid, acetamiprid, lambda-cyhalothrin, thiamethoxam, etc.; red spider: commonly used in general control agents are avermectin, bifenthrin, and sputum. You can choose the right medicine to spray according to your needs.
The above is about the prevention and control methods of red spiders, mites and other pests. In fact, Xiao Bian suggested that these plants should not be sprayed with pesticides for prevention even if they have worms. After all, health is the most important. In addition, in the case of insects, we can also manually capture pests. Generally, the pests are on the back of the leaves, and they can be removed in time.

Organic mung bean starch is a kind of powder formed by the precipitation of mung bean after soaking and grinding with water. Our organic mung bean starch follows the traditional processing ideas and combines modern industrial technology to achieve a more efficient, safer, and more hygienic processing level. The characteristics of mung bean starch are sufficient stickiness, low water absorption, white and shiny color.
Mung bean (Vigna radiata) is a plant in the legume family. Mung beans are mainly grown in India, China, and Southeast Asia. The Chinese have grown mung beans for nearly 2,000 years. They are ubiquitous in China, and there are many types, and numbers. Mung beans are also grown in other countries/regions in South Asia, North America, Brazil, and Europe. The main provinces for mung bean cultivation in China are Anhui, Henan, Hebei, Hubei, Liaoning, Shanxi, Shaanxi, and Sichuan.
The nutritional value of mung bean starch is very high, and its uses are also very wide. For example, mung bean starch has antibacterial, antibacterial, hypolipidemic, antitumor, and detoxification effects.
Mung bean starch contains a considerable amount of oligosaccharides (pentosan, galactan, etc.). These oligosaccharides are difficult to be digested and absorbed because the human gastrointestinal tract does not have a corresponding hydrolase system, so mung bean starch provides a lower energy value than other grains and has an adjuvant therapy effect for obese and diabetic patients.
