Farmers should check more when purchasing pesticides to avoid economic losses caused by purchasing unqualified pesticides. The Chinese Pesticide Network Xiaobian teaches you the main points to pay attention to when purchasing pesticides: In addition to understanding the information on agricultural materials, indicating the registration certificate of pesticides, the certificate of production of pesticides , and the address of the pesticide manufacturer , the pesticides must be marked with the active ingredients. If the pesticide is not labeled with the active ingredient, the specific disease or insect pest that can be controlled is not known. It should be regarded as a fake pesticide, and it is best not to buy it. For example, the active ingredient of Shigao is difenoconazole, and the active ingredient of Fuxing is flusilazole, which is a chemically synthesized fungicide.

Try to buy a single agent, use the compounding agent with two or more kinds of pesticides. The goal is to complement the insecticidal action and improve the control effect. The compounding of the fungicide is to inhibit or delay the disease. The resistance of the fungicide is produced. Jinleiduome Mn-Zn, anti-virus cockroach, kelu, Anke Mn-Zn, Xiansheng, moldy gram, etc. are all good bactericidal compounding agents. A large number of compound pesticides emerging in the market, some use a single agent mechanism similar, can not achieve synergistic effect; some are the compounding of pesticides to control different varieties of pests, although the formula is acceptable, but only in these pests to achieve prevention The indicator is applicable. It is difficult for two different varieties of pests to reach the control indicators at the same time. The use of such a compounding agent is actually a waste and increases the cost of medication.
For pesticides with high unit price, the cost of medicine is not necessarily high, and the cost of medicine is the first thing that farmers think of. However, it is usually found that the cost of pesticides with high unit prices is not high. For example, 40% Fuxing emulsifiable concentrate, per liter (kg) of Fuxing emulsifiable concentrate is priced at 700 yuan, and the commonly used concentration for controlling pear black spot disease is 8000-10000 times. Use 8000 times, that is, 8000 kg of water per kilogram of Fuxing plus water, according to each tree spray 15 kg of liquid every time, the cost of medicine per tree is 1.4 yuan. In the critical period of prevention and control of pear black spot disease, using Fuxing 3-4 times can achieve the effect of disease-free leaves and diseased fruit throughout the year. If a low-priced pesticide is used, because the use ratio is low and the number of uses is high, the cost of medication is not necessarily small, and the control effect is difficult to compare with Fuxing.
