What problems should be paid attention to when filling roots with fungicides? Please introduce that in order to prevent vegetable root diseases, vegetable farmers often use fungicides to irrigate roots. Although the effect is good, some matters needing attention in root irrigation must not be ignored, otherwise there will be side effects. First, the shed that has used bacterial fertilizer does not use fungicides to prevent disease as far as possible. For the land where bacterial fertilizer is used, it is easy to kill the biological bacteria in the bacterial fertilizer and make the bacterial fertilizer lose its fertilizer effect. If a disease has occurred in the crop, the root must be irrigated with a fungicide, and do not consider whether the biological bacteria in the bacterial fertilizer are injured or not, so as not to cause an outbreak of the disease due to the small and the big. Second, do not pour water in the shed a few days after root irrigation. Pouring water immediately after administration will reduce the concentration of the solution and affect the control effect. Therefore, try not to pour too much water within a few days after the fungicide is irrigated into the root. If there is a lack of water, you can slip a small amount of water in the planting ditch. It is appropriate to use the water surface to the ridge height of 1 to 3. Be careful not to spread over the ridge surface, so as not to dilute the concentration of traditional Chinese medicine in the soil. Third, the use of fungicides after root irrigation, once the emergence of wilting, yellowing, growth and other drug damage symptoms should be remedied in time. Watering immediately to dilute the concentration of traditional Chinese medicine in soil and spraying roots with rooting agent or Aidoushou or other root-promoting agents has a significant effect on relieving drug damage and restoring plant growth.
