Drug selection should be reasonable: choose a fungicide with strong targeting and high therapeutic function, do not blindly use drugs, reduce waste as much as possible, prevent delays in prevention and control, and reduce drug efficacy.
The concentration should be appropriate: the fungicide should be mixed with amino acid liquid fertilizer or hormones that stimulate root development. The concentration of the liquid should be no more than 1500 times to prevent the soil moisture (the soil moisture concentration around the crop root) from being too high. . Do not pour large water into the shed within 7 days after root irrigation, otherwise the concentration of the liquid will be reduced, which will affect the sterilization and disease prevention effect.
The soil organism must be balanced: the selected fungicide can not destroy the biological population and ecological balance inside the soil after being applied to the soil. If the shed has been used for bacterial fertilizer, try not to use root fungus to prevent disease. If crop diseases begin to occur and there is a rapid tendency to spread, it is a different matter, that is, do not consider the problem of bacterial fertilizer, and should immediately implement root irrigation to reduce losses.
Remediation of phytotoxicity should be timely: if a phytotoxic reaction occurs after root irrigation, if symptoms such as wilting, yellowing, and stagnation occur, the remedy should be promptly performed. Remedial measures: quickly pour water once to dilute the concentration of the liquid in the soil; promptly use rooting agent or love to take over or Yunda 120 to spray while rooting to relieve the phytotoxicity, prompt the roots to recover as soon as possible, let the plants turn Into normal growth.
