High-temperature medication in summer booths must be scientific and reasonable

During the high temperature period, medication should be carefully used. Summer spraying must be performed before 10 o'clock in the morning and after 3 o'clock in the afternoon. Do not use under high temperature and strong light near the noon to avoid phytotoxicity. Flowering during flowering period reduces the flowering period of vegetables to be more sensitive to pesticides, and it is prone to phytotoxicity at high temperatures. Therefore, spraying at the flowering stage should be avoided as much as possible. At the same time, the young tissue on the top of the plant is poorly tolerated, so be careful not to repeat spraying.
The compounding agent requires reasonable occurrence of phytotoxicity, which is related to the compounding of pharmaceuticals. Many farmers tend to save time and mix different types of pharmaceuticals, and they are prone to phytotoxicity. In order to enhance the effect of medication or to facilitate one operation, some farmers mix several agents and increase the concentration of the agent or react with some of the components of the agent, making it more prone to phytotoxicity.
Once a phytotoxicity occurs, the vegetable farmer should spray water immediately, and add 0.2% baking soda in the clear water. At the same time, spray the pesticides to ease the damage and promote the recovery of the plant. In addition, to strengthen the management of fertilizer and water, vegetables should be quickly watered once after the occurrence of phytotoxicity, and water soluble fertilization with water, promote root growth and development, improve vegetable resistance.
