In order to prevent vegetable root diseases, vegetable farmers often use fungicides to root to control vegetable root diseases. Although this method has a good effect, some precautions during root irrigation cannot be ignored. Otherwise, not only will it not receive the desired effect, but also side effects. The following three points should be noted for the bactericide filling: Pvc Roof Tiles,Plastic Roof Tiles,Synthetic Roof Tiles,Synthetic Glazed Roof Tile Shandong Gaoxin Chemical Co.,Ltd , http://www.gaoxinchem.com
1. Drug selection should be reasonable: choose a fungicide with strong pertinence 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. 2. 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 soil water content (soil moisture concentration around the crop roots). 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. 3. Soil biology should be balanced: the selected fungicides 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. Do not consider the problem of bacterial fertilizer, and immediately implement root irrigation to reduce losses.
Remedy for phytotoxicity:
If a phytotoxic reaction occurs after root irrigation, if symptoms such as wilting, yellowing, and stagnation occur, the remedy should be promptly performed. Pesticides Network Xiaobian teaches you the remedy: quickly pour a clear water to dilute the concentration of the liquid in the soil; timely use the rooting agent to spray while rooting to relieve the phytotoxicity, prompt the roots to restore vitality as soon as possible, and let the plants turn into normal Growing.
