Do not spray pesticides at high temperatures. Some farmers think that the higher the temperature, the better the insecticidal effect of pesticides. In fact, in the summer, when the high temperature and strong light are sprayed, most of the pests stop the surface activity, hiding in the cool backlight, the chemicals are not easily sprayed in place, and at high temperatures. Pesticide has a large loss of volatilization and rapid decomposition of the drug. Therefore, at this time, the efficacy of spraying is reduced. At the same time, at high temperatures, the drug is highly volatile, and the drug enters the human body through breathing and skin pores, which may easily lead to operator poisoning.
The second bogey crops are sprayed with dew. Some farmers like to spray in the morning when they are cool, but spray the medicine when the morning dew is not dry. First, the pests have not come out yet. Second, the medicine is diluted with dew after spraying to reduce the efficacy. Therefore, the insecticidal effect is not ideal.
The concentration of the three taboos is too high. Many farmers are still trying to save money in the hot summer season. When the concentration of the drug is too high, the drug solution is sprayed on the foliage of the crop, and the moisture is quickly evaporated, which is very likely to cause phytotoxicity.
Four bogey do not wear protective tools. Some farmers spray the medicine in the summer for the sake of coolness. They do not take any protective measures when spraying. They often wear shorts, short-sleeved squats, no masks, and even smoke while spraying. The above unscientific methods of operation often It will lead to the occurrence of pesticide poisoning incidents, so be careful.
In view of the above problems, we should pay attention to the following points: First, choose sunny operation, 8-10 am (after dew dry), 5-7 o'clock in the afternoon (before and after sunset), choose to spray when the pest activity is strong; second, be strict According to the instructions for the use of pesticides, scientifically match the amount of water. Generally, the dosage of liquid per mu is more than 50 kg. Third, it is necessary to wear protective clothing when spraying, with a mask. After spraying, it is necessary to clean the body with soap in time. Clean for future use.
Nowadays entering the summer, the high-humidity and high-humidity climate characteristics are conducive to the rapid growth of field crops, and also the high-risk period of various pests and diseases. Farmers' friends should do “four bogeys†when spraying pesticides.
