What should be paid attention to when bactericide is irrigated?

In order to prevent and cure vegetable diseases, fungicides are indispensable. For vegetable root diseases, bactericide rooting is the most effective way. Although the bactericide rooting operation is relatively simple, it also requires certain rules, otherwise the sterilization effect will be greatly reduced. Below, Xiaobian will introduce how to use the fungicide roots.

1. Drug selection should be reasonable

To choose a highly targeted and effective fungicide, do not blindly use drugs, so as not to delay the timing of prevention, while reducing waste as much as possible.

2. Appropriate application concentration

The bactericide should be mixed with amino acid liquid fertilizer or hormones with stimulating root development as much as possible. The concentration of the liquid medicine should not be higher than 1500 times, and the concentration of the soil liquid around the vegetable roots should be prevented from being too high, causing phytotoxicity.

Pay attention to related matters

First, soil biology must be taken into consideration. The selected biocide can not damage the biological population and ecological balance inside the soil after being applied to the soil. Of course, if the vegetable has been diseased and must be irrigated with a bactericide, it is not necessary to consider whether the beneficial microorganisms in the fertilizer will be damaged, so as to avoid the disease outbreak due to small loss.

Second, it is not suitable to water before irrigation. After watering, the bacteria will spread with the running water, causing more dead trees. At the same time, watering can easily lead to the decrease of soil permeability, causing hypoxia in the roots of vegetables, producing roots, reducing the stress resistance of the plants, and the pathogens are more susceptible to infiltration, which aggravates the occurrence of dead trees.

Third, it is not advisable to water immediately after irrigation. Watering immediately after rooting will quickly dilute the liquid in the soil and reduce the effect of sterilization and disease prevention. If there is water shortage, you can pour small water in the planting ditch. It is better to use 1/3 of the water surface to the height of the ridge. Never cross the ridge.
