What are the tips for spraying pesticides in summer?

Summer is a stage of rapid growth and development of various food crops, and it is also a period prone to diseases. Therefore, preventing diseases is one of the farmers' summer farm tasks. So what are the precautions for spraying pesticides in summer? How to spray pesticides in summer?

Nine points to note when spraying pesticides in hot and rainy weather. Do not use river water or wastewater to prepare pesticides. River water contains a lot of calcium, magnesium and other minerals. They are prone to chemical changes with the pesticides and form precipitation, thereby reducing the risk of pesticides. The potency of the medicine; wastewater containing too much residue will destroy the reliability of the medicine on the one hand, and on the other hand, the residue contained in the wastewater will clog the nozzle of the sprayer. Pesticide "secondary dilution" is a secondary dilution of pesticides.

The key function is to increase the potency and have a high drug safety index. Do not spray pesticides in windy, rainy or hot weather. Spraying when the wind blows will cause the pesticide (powder) to fall; when spraying on rainy days, the pesticide will be eroded by precipitation and reduce its potency. Applying pesticides at high temperatures can easily cause crop damage and body poisoning. Therefore, the best time to apply the pesticide should be between 8 a.m. and 11 a.m. on a sunny day (after the dew has dried) and between 4 a.m. and 6 a.m. at noon. Pesticides can be applied 24 hours a day on rainy days.

Do not use pesticides indiscriminately. Corresponding drugs should be selected based on differences in crop types, prevention goals and pesticide characteristics to further ensure symptomatic treatment; at the same time, be careful not to blindly increase the dosage, which will lead to increased pest resistance. While reducing the control effect, it is also prone to obesity. Suggestion: Regarding this point, I would like to remind everyone that you must follow the specifications of the drug instructions.

Because this series of labels are the results of rigorous experiments, if you want to try them in other The actual effect on the target can be achieved through small-area experiments. If successful, it can then be applied on a large scale. How to spray pesticides in summer? Nine points to note when spraying pesticides in hot and rainy weather. When spraying pesticides during the flowering period, be careful. Food crops are in the flowering and young fruiting stages. Their organs are young and have weak resistance to stress. They are prone to fertilizer damage and affect the flowering period. Everything is pollinated normally. Do not apply pesticides before picking crops because pesticides will leave residues on food crops.

Generally, the residue period of highly toxic pesticides is about 60 days, and the residue period of high-efficiency slightly toxic pesticides is about 15 days. If the drug is applied before picking (during the safety observation period), drug residues will remain on the harvested organs, and poisoning will occur after taking them. It is not necessary to use a single drug for a long time. The long-term use of one pesticide formulation will easily cause the pests to develop resistance and reduce the control effect. Once the pests develop resistance, the consequences will be unpredictable. It is recommended to replace the medication. Do not litter pesticide bottles and other recycling materials. Used pesticide recycling materials (residual small amounts of pesticides) must be concentrated and destroyed to prevent environmental pollution and harm to people, livestock, poultry, etc. Safety precautions should be taken when spraying pesticides. If your clothes are accidentally stained with pesticides, you should change your clothes immediately and wash your skin with soap. Wear a mask, rubber gloves and suitable clothing when applying medication to prevent the medication from contaminating your skin and eyes. After spraying, if you need to eat, drink, or smoke, you must first wash your hands, disinfect your face, and rinse your mouth.

Dispensing should be carried out in a reliable area away from domestic water sources and residential areas. How to spray pesticides in summer? The nine major points to note when spraying pesticides in hot and rainy temperatures are some common problems with taking pesticides in summer. Farmers must use drugs appropriately. If the medication is not taken properly, not only will it not be able to prevent diseases, but it will also cause May cause damage to humans and animals or air pollution.
