Corresponding to the five major problems encountered in crop planting - physiological diseases, invasive diseases, insect pests, grass damage , and the uniqueness of individual environments, several types of chemical agents have been developed to solve these problems, namely: growth regulators, sterilization Agents, insecticides , herbicides , auxiliaries. Growth regulator Production regulators are used to preserve flowers and preserve fruit, promote rooting, relieve phytotoxicity, enlarge fruits, promote early maturity, improve the ability of crops to withstand low temperature and drought, elongate plant tissues or inhibit cell growth. Each growth regulator has its own unique regulation, but the goal is to make the crop yield higher. The use of growth regulators will, to a certain extent, destroy the hormone balance inside the plant, and the plant will even become another species. Although it can help increase the yield as a whole, it is the same as the unused taste from the quality of the food and the taste of the fruit. Crops are difficult to compare. In terms of application, different types of regulators and metering are also used in combination with different time and time. It is similar in some respects to herbicides and similar to fungicides . Fungicide The application technology of fungicides is ever-changing. Under the measurement of different crops, different periods, various environments and various application methods, and the ratio of various medicaments to each other, a disease can have hundreds of diseases. Thousands of prescriptions, but some of them must be effective and cost-effective. Through our research, the application effect of fungicides will continue to increase. There are many kinds of fungicides, such as bacterial, fungal, and viral. Fungi are divided into higher fungi, lower fungi, protective, therapeutic, and the like. Insecticide The label of the pesticide product usually has a red line below it, as if it were to "see the blood". Although there are actually no pests with red blood, the purpose of the pesticide is to kill them or roll them away. The application of insecticides is much simpler than fungicides. Which type of pesticides kills which kind of insects, and the effect is good, depending on the resistance of the pests, the ratio of the medicaments, and the growth period of the pests applied. This requires understanding the characteristics of pests, which can be found on Baidu. Therefore, insecticides rely on a bit of rote memorization, and targeted and scientifically applied drugs can get good results. From the recent years, serious pests have become less and less, but the smaller the physique, the more difficult it is to prevent and control, which requires scientists to invent new compounds. herbicide These pesticides are the largest in the world. In the northeast, insecticidal fungicides are called "small drugs" and herbicides are "big drugs." The application technology of herbicides is relatively fixed, and the method of use needs to be very strict. All the specifications must be formulated by the R&D personnel of the compound, and then the future use technology is fixed according to a large number of experiments in different regions, and many of them are unchangeable. Some pharmacies must even be used on a fixed day in a certain period of time. It is also because of these strict characteristics that plant protection personnel have little guidance to farmers. However, herbicides, especially selective herbicides, have different manufacturing processes, different raw materials , auxiliaries, and formulations, and there are differences in product safety and efficacy. Therefore, plant protection personnel need to assist farmers in selecting.
