How to choose what to pay attention to when buying pesticides

    To choose symptomatic and pollution-free drugs, do not blindly choose and use poison

 

    Each kind of bactericidal or insecticide has its range of disease prevention and treatment, and it is also necessary to consider the selection of pollution-free pesticides on the basis of the right medicine. At present, there are common remedies for pollution-free diseases such as: prevention and control of round rotten fruit disease, and how many internal injuries Bacteriophage, Jinggangmycin, methyl thiophanate, chlorothalonil, etc., protective products such as mancozeb , carbendazim ( coumaine ) , thiram, bacteriophage, Bordeaux mixture, etc.; black spot disease of fosetyl aluminum salt has (invalid rot), mancozeb, Po Lai (polyoxin, polyoxin), Bordeaux mixture, tuzet, chlorothalonil, iprodione (扑海 因 ), etc.; control of apple leaf curler, cotton bollworm, peach small heartworm and other leafy food toxic dead cockroaches ( also known as Lesburn , also ruled cotton mites and Kang's whitefly, green blind cockroaches ) , diazinon (agricultural land music), Bt biological insecticides, methomyl (All Souls), Ju lipids (cypermethrin, etc.); prevention of hawthorn spider mite, apple red spider and spider mites (white spiders) are Avi bacteria , triazole tin; control of the golden leaf moth, there are chlorpyrifos, chlorpyrifos and so on. Use 哒螨灵 ( 螨螨净等 ) or tetrazine ( 螨死净, etc. ) to control the two-spotted spider mites, use tetramethylazine to control the spider mites and apple red spiders, and use scorpion to control the spider mites or Apple red spider eggs, carbendazim or methyl thiophanate to control red spot disease, with polymycin to prevent round rotten fruit disease.

 

    To use more simple and concurrent drugs, no or less use of compounding and special medicine

 

    Since simple drugs are mostly basic drugs for compound drugs, such as carbendazim in many compound fungicides, the active ingredient after the replacement of the compound drugs is carbendazim, but it can be sold at a high price with a new name, 1kg50% carbendazim 20 yuan or so. After the name change, it can be sold for more than 40 yuan. Therefore, it is generally advocated to use the "old" medicine of pure quality, with no or less use of compound medicine. At the same time, it can be solved with one kind of medicine without using two kinds of medicines, and it can be solved by using a special medicine to solve the problem without using a special medicine.

 

    To use more drugs from famous brands, no small factories or miscellaneous drugs

 

    In general, imported brand-name drugs are more reliable than domestically produced drugs. At the same time, the quality of domestic famous brand enterprises is more reliable than that of miscellaneous drugs, and the quality of large manufacturers is more reliable than that of small manufacturers.  

 

    If you want to calculate the cost and price, don’t spend money.

 

    The purpose of reducing costs is to increase efficiency. Most orchards in production have more than 20% cost-saving space for pesticides. A considerable number of fruit farmers believe that they can kill insects, and it is good to cure diseases. No matter the cost, the worst is flowers. Money bought medicines that could not cure pests and diseases. The price of each active ingredient can be calculated according to the content of the active ingredient, and then compared with the price of the active ingredient of the conventional pesticide, which one is cheaper to use; the compound medicine generally has a higher price.  

 

    Look at the labels and packaging, don't be fooled

 

    A look at the three certificates, production license, pesticide registration certificate, quality standard certificate, the three certificates are indispensable; second, see if there are active ingredients and content, are indispensable; three see whether there is a factory inspection certificate, there is no failure; Fourth, look at the name of the factory, address, zip code, date of manufacture, batch number, shelf life, lack of one is unqualified; five to see whether the packaging is shoddy, whether the packaging mouth is loose. At the same time, it should be used according to the dosage specified by the pesticide label.

 

    Try to test the bills first, don't try it and leave no evidence.

 

    In recent years, there are not many medicines that have real new ingredients in the prevention and control of pests and diseases. For a small number of new ingredients, it is necessary to do a small area test first, and then use it in large areas after successful. At the same time, ask the dealer for the bill when purchasing the medicine, in case there is no evidence in the event of phytotoxicity.
