2, unconventional. The new drug is a good medicine. This is the consensus of many vegetable farmers, but it is not. Many new drug names and new ingredients are springing up, blurring the eyes of many vegetable farmers. Moreover, there are some pesticides with incomplete "three certificates" and fertilizers produced without license. At the same time, some pesticides and fertilizer products have not been promoted. If there is not much understanding of their effects, they will be prone to problems when they are used. Experts remind: familiar with pathology and pharmacology, the right medicine is the right way, blind pursuit of the wind is not desirable.
3, the effect is magical. Many vegetable farmers are easy to mistake: the wide range of applications of medicines and fertilizers is a good product. If some pesticides indicate that they can treat various diseases such as fungi, bacteria and viruses, they are known as "the god medicine". A certain agent or fertilizer has a single action component and only has a good effect on certain diseases, and it is impossible to be effective for many types of diseases at the same time. Experts remind: the experience of growing vegetables should be summarized, the medicine and fertilizer components should be familiar.
4, too far behind. Excessive use of fertilizers and medicines is common in the current majority of vegetable farmers. Experts advise: the right amount of medication, fertilizer is very critical, too much to be really sad.
5. Use blindly. When many farmers use fertilizers and pesticides, they do not understand the nature of the selected agricultural materials and the physiological growth characteristics of the vegetables. As a result, the phenomenon runs counter to one another. Washing, spraying, bottom application, acupoint application, and ditch application are several common methods for the application of fertilizer in the application process. According to the different growth characteristics of plants and the characteristics of fertilizers and soils, choose the appropriate fertilization method and determine the amount of fertilizer. Infectious diseases and physiological diseases; fungal diseases, bacterial diseases, and viral diseases and nematode diseases are the primary identification of the difference between the diseases, and then the right medicine. Experts advise: medications and fertilizers should be based on actual conditions to prevent the use of pesticides and fertilizers out of date and aggravate.
6, multiple mixing. At present, many vegetable farmers use several fungicides in combination with micro-fertilizers, insecticides and viral agents, which not only enhance the resistance of pathogenic bacteria, but also easily cause phytotoxicity. Experts remind: the chemical science mixes to prevent resistance.
