Description and Uses

POTASSIUM PHOSPHITE: Disease Prevention and Bacterial Suppression: Rich in biostimulant phosphorous acid (containing +3 valent phosphorous acid), it can stimulate crops to produce polyphenols and reactive oxygen species (ROS), stimulating the activity of defense enzyme systems. It has good preventive and therapeutic effects on common fungal and viral diseases such as blight, downy mildew, root rot, and late blight. Regular use greatly improves the disease resistance and stress tolerance of crops. Safe and Efficient: It can be transported bidirectionally through the xylem and phloem, improving nutrient absorption and utilization efficiency. The nutrients are pure, hormone-free, and impurity-free, and will not clog nozzles or drip irrigation capillaries, making it safer for roots, leaves, flowers, and fruits. Loosens the soil, increases permeability, improves the rhizosphere environment, and is conducive to healthy and vigorous crop growth; Promotes Root and Plant Growth, Promotes Flowering and Fruit Enlargement, and Increases Yield: It can promote robust plant growth, effectively control apical dominance, avoid excessive vegetative growth, and make crop flower buds full, more and stronger, significantly improving fruit set rate and quality, thus increasing yield and income.
