POTASSIUM PHOSPHITE CAS No. :13977-65-6 Molecular Formula:� K3O3P Molecular Weight: 196.2669 Usage: 1.Anti-bacterial and antibacterial: rich in biostimulating hormone phosphorous acid (including +3 phosphinic acid phosphorus) can stimulate crops to produce polyphenols and reactive oxygen species (ROS), stimulate the defense enzyme system activity, against common diseases Fungal and viral diseases such as downy mildew, root rot and late blight have good preventive and therapeutic effects. They are often used, and the ability of crops to resist disease and stress is greatly improved. 2.Safe and efficient: through the xylem and phloem two-way transport, nutrient absorption rate, high efficiency, nutrient purity, no hormones, no impurities, no plugging nozzles and drip irrigation capillary, safer for roots, leaves, flowers, fruit. 3.Loose soil, increase permeability, improve the rhizosphere environment, is conducive to crop health, robust growth; 4.Promote roots and strong plants to promote flower expansion and increase yield: the use of this product can promote plant robustness, effectively control the top advantage, avoid plant vegetative growth is too strong, so that the crop flower buds full, more flowers and strong, fruit set rate and quality significantly increase production and income.
