It is not advisable to spray vegetables in winter and spring at noon.
In general, vegetable farmers do not spray at noon on sunny days in summer and autumn, because the temperature is high, it is easy to cause phytotoxicity. But in the cold winter and spring season, many vegetable farmers will choose to spray at noon. Their idea is that the winter and spring sheds have lower temperature and higher humidity, and they cannot be used quickly and better after spraying. If the medicine is sprayed at noon, the liquid will dry faster under the sunlight, and it will penetrate into the leaves better and improve the effect of the medicine. This idea is wrong. Whether it is winter or spring or summer and autumn, you should avoid taking medicine at noon on a sunny day. Because the high temperature at noon on sunny days can easily promote the decomposition of the drug and the evaporation of water in the liquid, the chemical activity of the agent becomes stronger when the weather is hot, and the toxicity of the pesticide becomes larger. Especially when spraying emulsifiable concentrates and various herbicides under high temperature conditions, it is easy to cause phytotoxicity and poisoning accidents of pesticides. Spray must avoid the high temperature of noon, then what time is the right spray? Generally speaking, in the cold season of winter and spring, the pesticide application time is preferably from 2:30 to 3:30 in the afternoon, and it is best not to use the medicine in the morning. Because the temperature in the shed is low in winter and spring, the photosynthesis gradually enters the peak period after the morning leaves dew, and the spraying will inevitably affect the temperature increase and reduce the photosynthetic efficiency. In the afternoon, it will not affect the temperature, which is beneficial to the prevention and treatment of diseases and insect pests. If it is in the continuous sunny weather in winter and spring, when the temperature in the shed is high, it can also be sprayed after 4 pm, which also plays a good role in sterilization and pest control.
