Precautions for the purchase and use of pesticides
Precautions for the purchase and use of pesticides 1. When purchasing pesticides, pay special attention to whether the “three certificates†on the pesticide label is complete. Formal pesticide company's product label has registration number, production license (some products are pesticide production approval certificate) and standard number. Incomplete products of the "Three Certificates" cannot be purchased. This pesticide is generally an informal manufacturer's product and often has quality problems. 2, when buying pesticides should see the composition of the active ingredients. Some products intentionally do not indicate the name of the active ingredient, do not indicate the content of the active ingredient, and have a very attractive or fashionable product name for the product, such as “XX PAâ€, “XX Spiritâ€, and “XX Netâ€. Some of the words marked "fine", "pure" and other national regulations cannot be used. The use of the same effect, but the sale price is much higher than other similar products, mislead and deceive consumers. Therefore, it should be noted that the name of the active ingredient and the content of the active ingredient are clearly marked on the label of the pesticide, and products that do not indicate the name of the active ingredient and the content of the active ingredient should not be purchased. 3, see the package amount of pesticide packaging. Pesticide packaging is generally expressed in terms of both weight and volume, and packaging specifications are also different. In the past, a 500-gram bottle was now available in various forms such as 450 grams, 480 grams, 425 grams, etc. The shape of the bottles varied, and it was difficult to judge the weight of the bottles. The proportion of pesticides in general is less than 1, so the same amount of pesticide is often expressed by weight more than the volume represents the actual loading. For example, 450 grams of pesticides are often more than 450 milliliters. 4. Do not purchase pesticides that are prohibited from use by the country. The pesticides that the state has banned from use include: DDT, toxaphene, insecticide, herbicidal ether, adversaribine, fluoroacetamide, fluoridation, tetramethasone, sodium fluoroacetate, and poisonous rat silicon. 5, do a reasonable use of pesticides. Indiscriminate use of pesticides can cause pollution to the environment, crops, aquatic products, and livestock; residual pesticides enter the human body through food, beverages, and respiratory channels. Long-term consumption of pesticide-contaminated foods can cause the accumulation of certain pesticides in the human body. Therefore, the rational use of pesticides is an important factor in ensuring personal health and the environment. It is important to use pesticides properly. According to the nature of different pesticides and the occurrence of pests and weeds, they can be used rationally and the best results can be achieved with the least amount of pesticides. This can save money and reduce pollution, and cannot increase or reduce the amount of pesticides used and the number of uses. Safe use of pesticides is also very important. The use of pesticides should be based on the interval between the last application of different pesticides and the time the crop is harvested. Vegetables that have not been stipulated for the number of days after the use of pesticides cannot be harvested. Vegetables that are harvested immediately should not use pesticides. The use of pesticides should be strictly in accordance with the instructions for use or relevant regulations. It is best to use pesticides under the guidance of pesticide use experts. In addition, pesticides that may not be used or restricted on vegetables, fruit trees, tea, and Chinese herbal medicines include: methamidophos, methyl parathion, parathion, monocrotophos, formazan, methylisotriphos, g 19 kinds of highly toxic pesticides such as Budweiser, aldicarb, etc. shall not be used on vegetables, fruit trees, tea, and Chinese herbal medicines. Dicofol and fenvalerate should not be used on tea plants. Any pesticide product must not be used beyond the approved scope of pesticide registration.
