Spraying pesticides in summer should be the best time between 8 and 10 am and 5 pm. Because around 9 am, the dew is generally dry, and the temperature is not too high. It is the sunrise insect pests that feed, move, and mate for the most vigorous time. Therefore, medication is not used to reduce the drug because it is washed or diluted with dew. Effectiveness will not affect the efficacy due to the decomposition of chemicals due to high temperatures.
On the contrary, the use of drugs at this time will increase the chances of pests feeding and touching drugs, effectively increasing the lethality of pesticides. Around 5 pm, the sun was already on the west side. At this time, the light faded and the nocturnal insects began to become active (feeding, mating, etc.). Therefore, at this time, the spraying has the same high killing effect.
How to use pesticides more safely
In the hot summer, it is the prosperous period of various crops and the period of occurrence of diseases, weeds and weeds. At the same time, it is also the prolific period of pesticide poisoning. Therefore, farmer friends must pay attention to the following points when applying pesticides:
1. Workers who strengthen labor protection should wear trousers, long trousers, gloves and masks as much as possible so as not to expose the skin. Bathe and change clothes immediately after application. Minors, people with dermatoses or mental illnesses, people who have not recovered from skin damage, people whose bodies have not been completely recovered after pesticide poisoning, people who have just had alcohol, men who have menstrual periods, gestational periods, breastfeeding, etc. No pesticides should be applied.
2, adjust the application time
The time of spraying should be as early as 10 o'clock in the morning or after 4 o'clock in the afternoon to avoid the high temperature period at noon. When applying pesticides, the spraying personnel must stand on the air outlet and spray it forward.
3. Control the amount of pesticides applied in high temperature seasons, reduce the dosage appropriately, increase the amount of liquid to be sprayed, and use effective low concentrations as much as possible to prevent the poisoning of pesticide application personnel and produce phytotoxicity to crops.
4. Forbidden mining, grazing bans, and fasting For plots of pesticides that have just been applied, clear signs should be set up to remind people not to mow inside, grazing, and eating fruits to prevent human and animal poisoning.
5, proper storage of pharmaceuticals, pharmaceutical machinery, pesticides and used pesticides equipment to special inventory, medicine bottles, medical equipment can not be cleaned in the fish pond, but can not use drug bottled oil vinegar.
Apply pesticides to achieve "six don't"
First, do not use sewage in the sewage. There are many impurities in the sewage. It is easy to plug the nozzle with its dispensing, and it can also destroy the suspension of the pharmaceutical and cause precipitation.
Second, do not use well water to mix well water with more minerals. The combination of these minerals and pesticides is prone to chemical reactions, precipitation, and reduced efficacy.
Third, do not use pesticides under stormy weather
Wind-blown spray will cause pesticide powders and liquids to drift; rain, pesticides, liquid medicine will be washed to reduce efficacy; under the hot sun, plant metabolism, leaf stomata expansion, prone to phytotoxicity. Optimum spraying time: 8 am to 10 am, around 5 pm
Fourth, do not abuse pesticides should be based on the type of crops, control objects and the performance of different pesticides using the corresponding pesticides, truly correspond to the drug, the abuse of pesticides often cause phytotoxicity.
Fifth, do not use a drug for long-term use of a drug, it is easy to make insect resistance, reduce control effect.
Sixth, do not spray before the harvest general high-toxicity pesticide residue period of about 60 days; high-efficiency low-toxicity pesticide residue period is about 15 days. Spraying before harvest can easily cause food poisoning.
