How to use pesticides for pollution-free strawberries

Non-polluted strawberries require fresh, clean, fresh, sweet and sour, and toxic and hazardous substances that are lower than the human safety standards. They should meet the double standards of nutrition and medicine. Under the present conditions, the production of pollution-free strawberries is inseparable from chemical pesticides. However, the principle of “strict, accurate, and appropriate” must be followed during use.
I. Strictly selecting pesticides and implementing pesticides during the safe period of pollution-free strawberry production When pesticides are used, strict screening should be carried out. Biological pesticides should be used preferentially, and chemical pesticides with high efficiency, low toxicity, and low residue should be used selectively. These pesticides mainly include: 1 insecticides. Bt series, avermectin series, pyrethrins, plant extracts (such as bitter lactone, capsaicin, etc.), insect hormones (mimantan, casketoxin, and cilostazol), and a few organophosphorus pesticides (enemy Insects, Lebenben, farmland music) and other pesticides such as imidacloprid. 2 fungicides. Bordeaux fluid, oxo-qing, thiophanate-methyl, sevoflurane, lucidum, chlorpyrifos, chlorothalonil, cyprostinil, methicillin, pyrimidine, etc. 3 Herbicides. Grass gram, cover grass and so on. 4 Aerosols Sulfur fumigants, quick-acting agents, extermination smoke agents, etc.
During the whole production process of strawberry, the use of methamidophos, carbofuran, insecticidal guanidine, omethoate, dicofol, methyl 1605, sodium pentachlorophenol, Kedandan, chloropicrin, and herbicidal ether are prohibited. Residue pesticides.
The amount of pesticide residues in fresh strawberries was closely related to the length of time from the last application to harvest time. Shorter intervals will result in more pesticide residues, and vice versa. Therefore, producers must strictly monitor the safety intervals of pesticides. Generally, it takes about 10 days before the strawberry is harvested or after it is harvested for pesticides to be marketed. Pesticides with a long residual effect, such as imidacloprid, should be marketed more than 15 days after application.
Second, pay attention to prevention and control strategies and accurately grasp the appropriate period of prevention and treatment According to the law of the length and length of pests, pay attention to prevention and control strategies, accurately grasp the appropriate period of control, accurate selection of suitable pesticides, have a multiplier effect, for example, control of red spider, should be mastered in the spot Stage; strawberry virus disease is closely related to aphids, as long as the prevention and control of aphids, the incidence of viral disease can be significantly reduced.
Third, appropriate, alternating and scientific drugs What kind of pests, what medicine to use, how much dose should be strictly controlled.
Pesticides must be used alternately to enhance efficacy and delay pest resistance. If mixed pesticides are to be used, they should be used immediately. The mixture must be checked before use. For example, mancozeb may be mixed with trichlorfon and dichlorvos, but not with Bordeaux mixture and limestone. Mixtures and other mix.
