Proper purchase of pesticides Each pesticide has a suitable range of use and a fixed control object, according to the type and period of occurrence of pests and diseases, to achieve the right medicine, select the type of pesticides to be purchased, and at the same time to do the drug purchase process: 1 Look at the packaging. All kinds of pesticides are toxic, so the pesticides produced by regular pesticide manufacturers are tightly sealed, the packaging materials are new, the sealing parts are clean, no leakage, no residue; the powder medicines are moisture-proof packaging, and the emulsifiable medicines are leak-proof bottle caps; The packaging and printing are exquisite, printed with registered trademarks, Chinese manuals, and active ingredients. At the same time, the state stipulates that all pesticide companies must have complete “three certificatesâ€, namely pesticide registration certificate, production license and product standard certificate. 2 look at the label. Qualified pesticides have labels or certificates, and the specifications, net weight, toxicity, common name, active ingredients, production date, expiration date, manufacturer name, site, instructions for use, and precautions must be clearly marked on the pesticide. ,Indispensable. 3 look at the appearance. Each pesticide has a fixed dosage form. The powder medicine should be fine, uniform, smooth, easy to dissolve, easy to disperse, and not squashed; the emulsion type medicine should have a uniform hue, transparency, no impurities, no delamination, no turbidity, and the like.
China Pesticide Network Xiaobian reminds everyone that if the following conditions occur, farmers should not buy, and can report to the industrial and commercial departments in a timely manner: First, check whether the packaging of pesticide products and the color pattern are more vivid or special, compared with similar pesticide products. The second is to check whether the name of the pesticide product is special, whether it contains absolute language, and the relevant laws are contrary; the third is to check whether the package name of the pesticide product has the clear basic name, address, telephone number and other basic contents; Is to check whether the product standard number, pesticide registration number, production approval number is clear, the labeling position and font color are conspicuous; the fifth is to check whether the pesticide packaging is rough, the sealing property of the packaging, whether there is pesticide spillover; the sixth is to check the packaging Whether it is marked with the words "imported original medicine, Japanese company technology, Swiss company supervision" and so on and ambiguous propaganda words; the seventh is to check the color and thickness of the pesticide, how it feels, whether it is the same as the genuine used . For emulsion pesticides, first look at whether the layers are stratified. If they are stratified, they can be oscillated up and down to make them uniform and then allowed to stand for one hour. If it is still stratified, it is likely to be invalid or fake.
The preparation of safe pesticides should be carried out in strict accordance with the requirements, and should not be increased or decreased at will. If the concentration is too large, it is prone to phytotoxicity. If the concentration is too small, the purpose of controlling pests and diseases will not be achieved. Before the new pesticide is used for the first time, it should be done in a small area test. After seeing the effect, it will be widely used.
