Points for attention of pesticides and fungicides for controlling crop diseases and insect pests

It is very troublesome to treat the root disease of crops once, and it is a simple and easy way to control the roots with pesticides. Pay attention to the following points when filling the roots.
1. Drug selection should be reasonable. Choose pesticide bactericides with strong pertinence and high therapeutic functions. Do not use drugs blindly, reduce waste as much as possible, prevent delays in prevention and control, and reduce drug efficacy.
2, the use of appropriate concentration of fungicides should be mixed with amino acid liquid fertilizer or hormones that stimulate root development, the concentration of liquid medicine should be no more than 1500 times, to prevent soil water content (soil moisture concentration around crop roots) 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.
3, soil organisms must take into account the choice of fungicides applied to the soil can not destroy the biological population and ecological balance within 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.
4, remedy of phytotoxicity should be timely irrigated after the occurrence of phytotoxicity reactions, such as plant wilting, yellowing, stagnation and other symptoms, should be promptly remedied. 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.
