Peasant friends' daily production and life are inevitably dealing with pesticides, but most farmers' friends use pesticides only by some customary conventions. However, there are many misunderstandings. For example, some farmers' friends will fight pesticides before pests occur in order to prevent the occurrence of pests and diseases. In fact, this is not true. What problems do farmers' friends have when using pesticides? Let's follow them with Xiaobian. First, no pests first fight drugs Our approach to “prevention-based†plant protection can be said to be familiar. It has been suggested that all the plants should be given medicine in the spring, and it is expected that this will prevent plants from causing pests and diseases. There is nothing wrong with the starting point, but prevention is not the first time to fight drugs? Of course not right. So how do you apply prevention to the production practice in a scientific way? Generally, no pests are found to fight drugs. Most of the drugs we use now are contact or stomach poisons, which means that they will come into contact with the body of the pest or be swallowed into the body by the pests. And we advocate the use of drugs in the early stages of pests, because it can maximize the role of pesticides and reduce the degree of plant damage. Because the disease has a certain incubation period, when we find that the plants show signs of damage (such as leaf spots, leaf blight, etc.), the bacteria have invaded the plant for a period of time. Therefore, we advocate early prevention for the disease, but we should master all kinds of diseases. The occurrence period and regularity of the occurrence, targeted advances to spray prevention. Second, pests and diseases do not use the wrong medicine Commonly used pesticides can be divided into insecticides , fungicides, rodenticides, herbicides, etc. The first two are the most widely used. Some production units are eager to treat after discovering that the plant has a symptom of injury. When the pesticide is bought, it is sprayed, and even spraying several times is not effective. The reason is that the disease is misused with pesticides. Such an example is not uncommon. Therefore, when the plant has symptoms of victimization, it is first necessary to judge whether it is a disease or a worm, and what disease is the worm. If you can't diagnose it yourself, it is best to ask a professional for guidance. Third, the reasons for unclear selection of drugs The current pesticide market products are dazzling, without a certain amount of expertise is really easy to choose the wrong medicine. We all know that the pathogens of plant diseases are fungi, bacteria, viruses, etc. Their choice of drugs is completely different. If you see the symptoms of the disease in the plants and do not find out the types of pathogens, such as virus disease, use fungicides or bacteria. The medicine is completely useless, not only wasted money, but more importantly, it delayed the treatment time, often causing irreparable serious consequences. Therefore, it is necessary to treat the disease. Time is not contraindicated. Not all pests and diseases are sprayed. It is determined by the law of the occurrence and development of pests and diseases. For example, common scale insects have a waxy protective layer for most of the life. In order to prevent the liquid from entering the worm, it is almost impossible to spray. Therefore, we choose to apply the drug in the initial incubation period without the protective layer. This effective time is often very short. Therefore, in addition to choosing the right medicine, it is also necessary to choose the time for applying the medicine. Fourth, do not read the instructions to dispose of drugs It is often the case that in order to rush to cure plant diseases and insect pests or to be afraid of drugs, it is easy to increase the concentration of the drug during dispensing, so that plants are not only easy to produce drug resistance, but also highly susceptible to phytotoxicity. . Conversely, the random reduction of the dose also does not achieve the control effect. Therefore, we can strictly follow the concentration ratio on the drug label when using the drug. Five, the treatment is not difficult enough Some pests and diseases can be removed from the disease, and once effective. Others need to be completely cured after several consecutive days of medication. For example, red spiders and aphids in insects often overlap in generations, that is, eggs, nymphs, and adults coexist, and most of the agents have no effect on eggs. Therefore, it is necessary to continuously apply the pesticide 2 times to 3 during the continuous incubation process of the pests and the effective period of the drug. Times. The prevention and treatment of diseases generally requires three consecutive sprayings from 3 days to 5 days.
