In order to prevent vegetable root diseases, vegetable farmers often use fungicides to irrigate the roots. Although the effect of this method is good, some precautions cannot be ignored. Otherwise, not only will it not receive the desired effect, but also have side effects.
Fertilizer selection
The sheds where the bacterial fertilizer has been used should not be rooted with a bactericide as much as possible to avoid killing the biological bacteria in the bacterial fertilizer, so that the bacterial fertilizer loses its desired effect. However, if the root disease has already occurred in the vegetable, the biological bacteria in the fertilizer can be ignored, so as to avoid small loss.
Avoid pouring water after filling the roots
After a few days with the bactericide, the shed can not be poured with large water, so as to avoid diluting the concentration of the liquid in the soil and affecting the disease prevention effect. When the vegetables need to be watered, they can slide small water in the planting ditch, and it is better to use the water surface to 1/3 of the ridge height.
Suffering from remedies and timely remedies
After irrigating with a bactericide, symptoms such as wilting, yellowing, stagnation and other phytotoxicity should be remedied in time to avoid loss.
The remedy is:
1. Quickly water to dilute the concentration of the liquid in the soil.
2. In time, use rooting agent to spray and root at the same time to alleviate the phytotoxicity and restore the growth of the plant.
