In the high summer season in midsummer, it is the high incidence of various insect pests. In order to reduce the loss of pests and diseases, farmers have to spray chemical pesticides. Some farmers are spraying pesticides during the high temperature season. Due to improper technology control, they not only failed to achieve the desired control effect, but also affected their own safety. Experts suggest that in the hot season, there are the following "five taboos and five mores":
Avoid spraying pesticides when the temperature is too high. Some farmers like to spray medicine when the sun is strong and the temperature is high at noon. It is believed that the higher the temperature, the better the volatilization of the pesticide, and the better the insecticidal effect, it is not. Because of the high temperature and strong light, most pests stop their activities and hide in cool and shaded areas. At this time, pesticides are not easy to hit on “targets†(pests). At the same time, under high temperature conditions, pesticides decompose rapidly and lose large amounts of volatiles. Therefore, when the temperature is high, spraying, the efficacy will be reduced. And spraying at this time, it is easy to cause pesticide poisoning.
Avoid spraying pesticides when the dew is still dry. Farmers also like to spray when the morning cool, but at this time if the dew does not dry, first, pests have not yet come out of activity, and second, after spraying the drug is diluted by dew, will reduce the efficacy Therefore, the insecticidal effect is also not ideal.
Bogey to increase the concentration of liquid medicine Many farmers in order to improve ergonomics, usually less watering when spraying, still in the high temperature season in midsummer. If the concentration of pesticides sprayed is too high under the high temperature of the hot sun, the leaves of the plants will be easily damaged because the moisture evaporates quickly.
Do not charge the drug when the over-abundant farmer sprays, like the sprayer barrel filled with liquid medicine. If the lid is not closed tightly, the liquid splashes on the person while walking and it is very easy to cause poisoning in summer.
Bogey without protection spraying some farmers in the hot season spraying as cool, spraying do not take any protective measures, and sometimes even do not wear shirts "bare shirts", if it is a giant poison pesticides, easily absorbed due to skin absorption of pesticide poisoning.
Appropriate medication time should try to avoid the noon high temperature weather, choose early and late time medication, before 9 o'clock in the morning and 5 o'clock in the afternoon is better. Do not apply more than 3 hours per application. Do not apply drugs on windy or wet days.
High-toxic pesticides should be banned from spraying high-toxicity pesticides during the high-temperature season. Medium- and low-toxicity pesticides should be used, and they should not be mixed blindly so as not to increase toxicity, reduce efficacy, and produce phytotoxicity.
To dispose of pesticides, it is forbidden to use the caps to pour medicine after the “six bansâ€; prohibit the use of drinking water buckets to dispense medicines; prohibit the use of drums for the accumulation of liquid medicines directly into the wells, ditch, and river to carry water; prohibit the direct use of pesticides by hand; prohibit the use of pesticides around drinking water sources. Dispensing; prohibit empty litter bottle.
Protective measures should be done well to wear protective equipment, such as masks, gloves, long pants, etc.; to be in the limelight; to clarify the application in accordance with the application of pesticides.
Control procedures should be standardized in the application of pesticides in accordance with the rules of management, the wind down the interlaced spray, do not drink before spraying, do not eat during the spraying, no smoking, wash immediately after the end of the application of soap, bathing, changing clothes. Also, clean the sprayer in time.
