Bactericide should not be watered before and after root irrigation

It is not advisable to water before using the fungicide. First, because the root disease of the crop has already occurred, if it is watered, the germ will spread with the running water, causing more dead trees. Second, because watering easily leads to a decrease in soil permeability, roots are deprived of oxygen, roots are produced, and stress resistance is reduced, making pathogens more susceptible to infiltration. In addition, after watering, rooting, the liquid is more difficult to infiltrate, too much medication is also easy to make the soil more poorly permeable, easy to cause crop roots, and increase the occurrence of dead trees, so it is not suitable to water before rooting.

It is not advisable to water immediately after rooting with a bactericide. Watering immediately after rooting will quickly dilute the liquid in the soil and reduce the effect of sterilization and disease prevention. Therefore, try not to water the water within a few days after using the bactericide to fill the roots.

After using the bactericide to fill the roots, once the crop has symptoms such as wilting, yellowing, and stopping growth, it can be rehydrated to avoid large losses. Remedial measures: First, quickly watering once to dilute the concentration of the liquid in the soil; second, timely use rooting agent or love to take over or Yunda 120 spray and root irrigation, which will help alleviate the damage and restore the growth of the plant.
