What should we pay attention to when filling the root with fungicides? Please introduce that root irrigation with fungicides is a simple and effective measure to control crop root diseases. But when filling the root, you should pay attention to the following points. The choice of drugs should be reasonable: choose fungicides with strong pertinence and high therapeutic function, do not use drugs blindly, reduce waste as much as possible, prevent delay in prevention and treatment, and reduce efficacy. The concentration should be appropriate: fungicides should be mixed with amino acid liquid fertilizer or hormones that stimulate root development as far as possible, and the concentration of the solution should not be higher than 1500 times to prevent soil water content (soil water concentration around crop roots) from being too high. Do not irrigate heavy water in the shed 7 days after root irrigation, otherwise the concentration of the solution will be reduced and the effect of sterilization and disease prevention will be affected. Soil biology should be taken into account: the selected fungicides can not destroy the biological population and ecological balance of the soil after being applied to the soil. If bacterial fertilizer has been used in the shed, try not to use fungicides to prevent disease. If crop diseases begin to occur and show a trend of rapid spread, it is a different matter, that is, do not consider the problem of bacterial fertilizer, root irrigation should be carried out immediately to reduce the loss. The remedy of drug damage should be timely: if the drug damage reaction occurs after root irrigation, such as plant wilting, yellowing, lag and other symptoms, it should be remedied in time. Remedial measures: quickly pour clear water to dilute the concentration of soil traditional Chinese medicine solution; timely use rooting agent or Aidoushou or Yunda 120 to spray and irrigate roots at the same time, in order to alleviate drug damage, promote root system to restore vitality as soon as possible, and let plants grow normally.

Why should fungicides not be watered before and after root irrigation? Please introduce the reason why it is not suitable to be watered before root irrigation with fungicides. First, because the root disease of crops has already occurred, if watered, the germs will spread with the running water, resulting in more dead trees. Second, because watering can easily lead to the decline of soil permeability, root hypoxia, production.
