Discussion on agricultural sprayer machine spray techniques and problems

Time and temperature requirements for pesticide spray:
Pesticide spray time should avoid midday, high temperature and high photosynthetic period. When the temperature is higher than 28 DEG C, it is easy to produce pesticide damage and affect photosynthesis. When the temperature is lower than 20 degrees, the plant absorption is poor, and the control effect is reduced. The best temperature of spraying pesticide is between 22 and -28 C, the absorption is quick and the effect is good. Pesticide spray time should be in the morning after a clear morning and afternoon.
Pesticide spray method and interval:
Spray pesticides should be uniform and spraying the leaves opposite the lesion at the back, spraying pesticides is more important, because bacteria leaves back, the other on the back of the absorption rate is more than double positive quick absorption, high control efficiency.
Spraying interval: three drug, pesticide spray times too much or too much damage to the concentration of leaf and leaf cell membrane, thereby reducing the resistance of the bacteria, accelerate the breeding of bacteria, leading to more and faster onset or exacerbation. Therefore, excessive, excessive side effects of drugs is very large, the most likely to produce injury and resistance, treatment is more difficult than treatment, treatment for a long time, affecting the yield and efficiency. Therefore, it is necessary to spray pesticides, pesticide spray interval is generally about 7 days for a good, at least not less than 5 days.
