Pesticide pesticide use common sense and reasonable
1 What is the pesticide
Pesticide is used to prevent, eliminate or control hazards in agriculture, forestry, disease, insects, grass and other harmful organisms, and regulation of plant, insect growth products.
Pesticide products can be divided by use of insecticides, fungicides, herbicides, plant growth regulators, rodenticides, fumigants, synergists, weeding security agent types. Under the control of different objects, we will control the pest pesticide known as pesticides, prevention and control red spider called acaricides, fungicides control plant pathogens is called, control weeds as herbicides, control of rodents as rodenticide so.
For example: methyl parathion and carbofuran pesticides should one of the main pesticides pesticides.
2, the types of pesticides
Insecticide mode of action of pesticides vary, there are stomach poisons, contact insecticide, fumigant, Agents for, attractant, repellent, antifeedant, infertility drugs, insect hormones. Is an insect stomach poison to pharmaceutical absorbed through the digestive organs showed cytotoxicity; contact toxicity of pharmaceutical agents is mainly exposed to insects, insect body surface through the body and play a role in invasion to kill insects; fumigant gas state can be circulated in the air in the respiratory tract invasion by insect larvae to death; within the absorption of pharmaceutical agents is generally passed by the roots, stems, leaves or seeds absorption, when the insects taking the juice of this plant, it will make poisoning of pharmaceutical inhalation Worms death. Another attractant: Pharmacy together can trap insects in order to kill or pesticide poisoning; repellent: the insect to drive away, the crop is immune or protected object; antifeedant agent: After refusing the role of insect feeding under the Pharmacy to die of hunger; Sterility: the role of the pharmacy, the insects lose their reproductive capacity, thus reducing the number of pests. For example, carbofuran is pesticides, acaricides, and nematicides. Mainly used in alfalfa, sugar beets, cereals, citrus, coffee, cotton, grapes, fruit trees, soybeans, corn, potatoes, rice, sugar cane, tobacco and vegetables. The seed coating products containing carbofuran for soybeans, corn and other seeds before planting on the surface coating used, the purpose is to control soil pests and foliar pests.
3, and pesticide toxicity of pesticides
Certain toxic pesticides. Pesticides used improperly or eat vegetables and other foods containing pesticide poisoning will. Poisoning with acute and chronic.
Acute toxicity is caused by pesticides enter the body a short time after the poisoning. Chronic toxicity of pesticides is a long-term absorption of a small amount of pesticide, pharmaceutical accumulation in the body, causing damage to the human body function caused by chronic poisoning. Some agents may not be low-dose short-term administration of toxic, but the long-term continuous absorption, toxicity will gradually become apparent.
Part of the pesticide application are not easily decomposed, there are still some or most of the residues in the soil, crops. These pesticide residues in food to achieve a certain concentration, long-term human or animal consumption, will allow pesticide to accumulate in the body, causing chronic poisoning.
Some pesticides in use, it may adhere to plant appearance, it may penetrate into the plant itself, absorbed by crops. Although these pesticides due to external factors such as sunlight, rain, dew, temperature effects and the role of plants, the gradual decomposition disappeared, but slowly. At harvest time, such as spraying inappropriate agricultural products often have a certain amount of pesticide residues, especially close to harvest crops too much fertilizer, too thick of pesticides in agricultural products will result in an excessive amount of pesticide residues. Therefore, the proper use of pesticides is very important.
Second, pesticide purchase and use precautions
1, purchase of pesticides should be taken on the pesticide label "three cards" are complete.
Regular pesticide business registration No product on the label, production licenses (some products of pesticide production approval certificate) and standard number. "Three Card" was incomplete product can not buy. This general non-formal pesticide plant products, often of questionable quality.
2, buy pesticides should see the active ingredients.
Some products deliberately not specified the name of active ingredients, active ingredients do not explain the content of the product from a very attractive or very trendy brand name, such as "¢ú ¢ú tyrants", "¢ú ¢ú Spirit", "¢ú ¢ú net" and so on. Some marked "excellent", "pure" and other state regulations can not use the words. Use the same effect, while the sales price is much higher than other similar products, mislead and deceive consumers. Therefore, care should be clearly marked on the label pesticide active ingredients out of the name and active ingredient content of active ingredients that do not note the name and active ingredient content of products not to buy.
3, see the packaging of pesticides in the amount of packaging.
Pesticide packaging weight and volume of two general said, packing specifications also vary. 500 grams bottle of the past generally, there are 450 grams, 480 grams, 425 grams, etc. are all forms, the shape of the bottle is not the same, difficult to judge from the appearance of view of their weight. General pesticide proportion is less than 1, so the same number of pesticides are often expressed in weight than the actual size of that quantity installed. For example, 450 grams of pesticides are often to be more than 450 ml.
4, do not buy the national ban on the use of pesticides.
States banned the use of pesticides are: DDT (DDT), toxaphene, chlorphenamidine, nitrofen, dry pair of the enemy, fluoroacetamide, Gan F, tetramine, sodium fluoroacetate, rat poisoning silicon, etc..
5, make rational use of pesticides.
Indiscriminate use of pesticides can cause to the environment, crops, aquatic products, livestock pollution; through food, drink, breath and other channels of pesticide residues into the human body. Long-term consumption of pesticide-contaminated food, the body can cause the accumulation of certain pesticides. Therefore, rational use of pesticides is to ensure that human health and the environment an important factor.
Rational use of pesticides is important. According to the nature of different pesticides and the incidence of pests, rational use, with the least amount of pesticides to achieve the best effect, not only save money and reduce pollution, must not increase or reduce pesticide use and frequency of use. Safe use of pesticides is also important. Pesticide use should be based on different pesticides from the crop harvested last interval medication use provisions, there is no requirement to the number of days after treatment can not be tapping the vegetables, cut the vegetables at once adopted should not use pesticides. Pesticide use should be strictly according to instructions, or the relevant provisions, it is best to use in pesticide use under the guidance of experts.
In addition, vegetables, fruit, tea, herbal material may not be used and restrictions on the use of pesticides are: methamidophos, methyl parathion, parathion, monocrotophos, phorate, methyl isobutyl Liu P, carbofuran, aldicarb and other 19 kinds of high-toxic pesticides shall not be used for vegetables, fruit trees, tea, herbal material on. Dicofol, fenvalerate not be used for tea plants. Shall not exceed any pesticide product registration approval of the use of pesticide use.
