What should be noted when using fungicides as a soil drench? Please explain
Note the following points when using fungicides as a soil drench:
First, in greenhouses where bacterial fertilizer has already been applied, try not to use fungicides as a soil drench for disease prevention. For land where bacterial fertilizer has been used, applying it tends to kill the beneficial bacteria in the bacterial fertilizer, causing the fertilizer to lose its effectiveness. If the crop has already developed disease, then you must use a fungicide as a soil drench, and no longer consider whether the beneficial bacteria in the bacterial fertilizer are harmed, so as not to lose the greater for the lesser and cause an outbreak of disease.
Second, do not water heavily in the greenhouse within a few days after the soil drench. Watering heavily immediately after applying the fungicide will reduce the concentration of the solution and affect the control effect. Therefore, within a few days after the fungicide soil drench, try not to water heavily; if water is lacking, a small amount of water can be run along the planting furrow, with the water level reaching 1/3 of the ridge height as appropriate, and be careful never to let it flow over the ridge surface, so as to avoid diluting the concentration of the fungicide solution in the soil.
Third, after using a fungicide as a soil drench, if symptoms of phytotoxicity such as wilting, yellowing, or stunted growth appear, remedial measures should be taken promptly. Water once immediately to dilute the concentration of the fungicide solution in the soil, and promptly spray or drench the roots with a rooting agent or Aiduoshou or other root-promoting agents, which has a significant effect on relieving phytotoxicity and restoring plant vigor.
