1. Choose pesticides. Choose pesticides and beware of counterfeiting. Do two things: one is four. Look at the look and packaging. Qualified pesticides are neat and clear. The emulsifiable concentrate is transparent, non-precipitating and non-layering; the soluble powder powder is light, fine, loose, uniform in fineness and non-caking; the suspension is a fluid liquid with good suspension, precipitation or stratification, the upper part is Water, the lower part is effective, but it is slightly vibrated and dispersed, and it recovers good suspension; the suspension has no sedimentation and no delamination. Second, see if the "three certificates" are complete, that is, whether there are pesticide registration certificates, production licenses, and standard certificates on the labels. Third, look at the label on the factory name, site, zip code, telephone, production date, and validity period. Fourth, see if there is a certificate in the medicine box. The second is the test. Pour a pot of water, put a little medicine, if it is powdery, the high-quality medicine is scattered, the inferior medicine sinks, because the quality medicine is fine, it is 300-500 mesh, the inferior medicine is thick, it is more than 100 mesh; if it is emulsifiable, it can quickly disperse It is a good medicine to open, and it is inferior medicine that cannot be dissolved. The better the medicine is, the faster it is, because the good medicine has good emulsifying properties. (2) Select pesticides that are pollution-free and low-residue, and do not use pesticides that are prohibited by the state. Choose mineral source pesticides with good effect and low cost, stone sulfur mixture and Bordeaux mixture. Choose a good medicine that has been proven by practice, and do not pursue new drugs. Because new drugs are generally expensive and the effect is not stable.
2. The right medicine. According to the pests and diseases of the park, we should choose the specific drugs that have a killing effect on the pests and diseases, and we should not follow the big flow.
3. Timely medication. It is necessary to find out the effect of the key period of spraying. To prevent disease, spray before the onset and at the onset of the disease, and treat the insects in the first and second generation eggs and during the incubation period.
4. Reasonable mixing. Mixing pesticides can save time and spray times, but generally no more than three types: insecticides, fungicides, and micro-fertilizers. The two pesticides, the acidic and alkaline pesticides, the stone sulphur mixture and the Bordeaux mixture can not be mixed.
5. Alternate medication. Refers to the prevention and control of a pest and disease to use different pesticides with different active ingredients to prevent disease and insect resistance.
6. Scientific dispensing. Whether the dispensing is reasonable or not directly affects the efficacy. First, pay attention to water quality. It is best to use deep well water instead of pond slope water, rain water and alkaline water. The second is to rationally exchange water. It is best to first prepare a mother liquor, dilute the stock solution with warm water and then dip it with water. Moreover, when dispensing, first pour half of the water, then pour the medicine, and finally pour half of the water, which will promote the drug to dissolve fully. If the water is poured after pouring the medicine, the medicine will react with the iron barrel to reduce the effect of the medicine; if the medicine is poured after pouring the water, the effect will not be fully exerted. The third is to accompany the use. Especially when several pesticides are mixed, this should be done in case the temperature is too long and the quality changes.
7. The concentration is appropriate. Do not arbitrarily increase the concentration of the drug solution to avoid phytotoxicity.
8. Spray carefully. First, it is even and detailed. Spraying must be meticulous and uniform to ensure the effect, especially the contact-killing insecticide. Only the agent can contact the pests to eliminate the pests. If it is not uniform, the pests that are not sprayed will leak out of the net, and the next time you spray, you miss the best time. Second, the atomization is better. The air pressure is large, the eye of the nozzle is small, and the smaller the smaller the atom can be fully atomized, the penetration force is enhanced, and the effect can be enhanced. It is necessary to prohibit the spray gun from entering the orchard. Because the spray gun is used in a large amount, it is half used more than the spray head, and the degree of atomization is poor, and it is easy to spray the leaves and fruits to produce fruit rust.
