Many farmers' friends have the mentality of “willing to give medicine and not willing to use water†when spraying pesticides. This is unscientific, so how to control the dosage and the amount of water is the best? What is the dose? That is, the amount of 1 acre or 1 hectare of pesticide used, also called the amount used. This amount can be as many grams as a pure drug, or as many grams, granules, or as many milliliters of cream. In the instructions for use, the dosage of the drug is more suitable for the user to formulate the drug directly, but the amount of the drug should be taken into account. With different contents, the usage per acre is different. In some pesticide use instructions also use spray liquid concentration (such as 1000 times liquid) to guide the use. This is usually regulated by a constant amount, that is, 30 to 100 liters per acre. Only by ensuring the amount of liquid spray can an effective dose be guaranteed. The use of various pharmaceutical agents is determined after years of research and experimentation by experts. In addition to ensuring the effectiveness of control objects and the safety of crops, economic factors are also considered. In other words, you can increase the amount of drug, but the loss will not exceed the increase in the cost, it is not worthwhile. Moreover, increasing the amount of drugs may also cause phytotoxicity or increase environmental pollution, or even endanger the safety of agricultural products, and the consequences may be very serious. Therefore, generally do not arbitrarily increase the amount of pesticides used. Of course, in areas where drug resistance occurs, it is necessary to increase the dose in order to ensure the control effect, but this cannot be said to be a general phenomenon. There may be a variety of reasons for the poor control effect. Among them, "not willing to use water" is also one of them, and it is more common. Pesticides are essentially sprays of water on the surfaces of crops or pests and colonies. To fully spray, or pests will not die. In order to achieve good dispersion, the spray volume should be matched with the power of the sprayer, the working pressure, and the diameter of the spray droplet. Usually when using a backpack mist sprayer or a hand sprayer with a small-diameter jet, the droplets are very small. The amount of liquid sprayed per mu can be controlled within a low capacity range of 0.5 to 30 liters, often with 5 to 10 liters. Can achieve good control effect, and in the use of Gongnong-16 type knapsack sprayer, due to the pressure is small, spray droplets large and have to increase the spray pressure to increase the dispersion, generally 30 to 100 liters per acre . We understand that some people use less water to get drugs quickly and suffer less. But science can produce the best results for water.
