When applying fungicides as a soil drench to prevent pests and diseases, note the following points:
1. The choice of product must be reasonable:
Choose a fungicide that is highly targeted and has a strong disease-control function. Do not use products blindly; minimize waste as much as possible, avoid delaying the timing of control, and prevent reduced efficacy.
2. The concentration used must be appropriate:
As far as possible, mix the fungicide with amino acid liquid fertilizer or a hormone that stimulates root development. The concentration of the solution should preferably be no higher than a 1500-fold dilution, to prevent the soil moisture content (the concentration of soil moisture around the crop roots) from becoming too high. Within 7 days after the soil drench, do not irrigate heavily in the greenhouse, otherwise the concentration of the solution will be reduced, affecting the fungicidal and disease-prevention effect.
3. Soil organisms must also be taken into account:
After the selected pesticide fungicide is applied to the soil, it must not destroy the biological community and ecological balance within the soil. For example, in greenhouses where microbial fertilizer has already been used, try not to use fungicides as a soil drench to prevent disease. If crop disease begins to occur and shows a trend of rapid spread, that is a different matter: do not consider the microbial fertilizer issue and immediately carry out the soil drench to reduce losses.
4. Phytotoxicity remedies must be timely:
If a phytotoxic reaction occurs after the soil drench, such as symptoms of plant wilting, yellowing, or stunted growth, remedial measures should be taken promptly. Remedial measures: immediately apply a thorough watering with clean water to dilute the concentration of the solution in the soil; promptly spray and simultaneously drench the roots with a rooting agent, or Aiduoshou, or Yunda 120, to alleviate the phytotoxicity, encourage the root system to recover its vitality as quickly as possible, and allow the plants to return to normal growth.
