After treatment, the diseased roots can be cured within 1-2 months, and new roots can be grown to normalize the growth and development of fruit trees.
Second, the prevention of downy mildew: plant ash is rich in potassium, potassium in the photosynthesis is conducive to the operation and storage of carbohydrates, while potassium can also promote the maturity of leaves and leaves thickening of the stratum corneum, thus effectively resisting the downy mildew The invasion of the disease. The specific method is: July-August fruit after the expansion period, in the ground to spread plant ash or in the tree tray ditch application, can also be used 4% of the ash leaching liquid foliar spray, that is, every 3-4 kg of grass ash plus 100 kg of water , Leaching liquid spray after 24 hours of immersion, the effect is better.

It is suitable for general hygiene care activities, such as sanitary cleaning, liquid distribution, cleaning bed units, etc., or the blocking or protection of particles other than pathogenic microorganisms such as pollen.
Conforms to the relevant registered product standard (YZB), generally lacks the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks, only reaching 20.0% for 0.3μm diameter aerosols -25.0% protection effect, can not reach the filtration efficiency of particles and bacteria, can not effectively prevent pathogens from invading through the respiratory tract, can not be used for clinical invasive operations, nor can it protect particles and bacteria and viruses, only limited to dust particles Or aerosol plays a certain mechanical barrier.
