Pay attention to pesticides in summer

First, we must pay attention to the rational use of pesticides
1, the right medicine. There are many varieties of pesticides and different characteristics. The most suitable pesticides should be selected for the control objects.
2, timely medication, medication time is right, anti-effect is ideal. For example, protective fungicides must be used before or during the onset of the disease. Herbicides should be applied correctly in different dosage forms, such as pre-emergence application and stem and leaf treatment.
3. Strictly control the amount of application. Any pesticide should be used according to the recommended dosage. It is easy to increase or decrease the pesticide to cause crop damage or affect the effect.
4, the application should be even and thoughtful, can not be re-sprayed or leaked spray to ensure the safety of crops, effective against pests and diseases.
5. Reasonably mix pesticides. After mixing, the toxicity to humans and animals should not be increased, chemical changes should not occur between the active ingredients, and the cost of medication should not be increased.
6, to safely apply drugs, disable high-toxic pesticides. Dispensing and applying drugs should prevent pesticides from corroding the skin, and it is forbidden to spray pesticides at high temperature during noon in summer. Do not apply too long for continuous application. Keep the liquid at the spraying site to prevent poisoning of humans and animals. Especially for biological pesticides, ultraviolet rays in the sun have a killing effect on spores. Direct sunlight can be used for 30 minutes, spores can kill about 50%, and when exposed for 1 hour, the mortality rate is as high as 80% or more. Therefore, the application of bio-pesticide can be applied after 4 pm, cloudy and no heavy rain, and can be applied throughout the day.
Second, pay attention to problems in time to deal with 1, when the efficacy is very poor or produce phytotoxicity, the drug should be sent to the pesticide testing unit for inspection. If it is unqualified or fake, you can go to the industry and commerce, consumer association, technical supervision department to complain or to The court sued.
2, the occurrence of remedies in a timely manner. First, the fertilization remedy, the phytotoxicity of the leaves on the surface of the drug spots, leaf edge coke or plant yellowing, can increase the application of fertilizer to reduce the degree of phytotoxicity, generally used leaf surface top dressing to remedy; the second is to inhibit or interfere with plants The herbicides that grow can be irritated by spraying gibberellin.
