Potassium phosphite is mainly used for sterilization and disease prevention, activating the active defense mechanism of crops, inducing crop immunity and improving the crop’s own resistance to diseases; supplementing phosphorus and potassium fertilizer antioxidants; and precipitating heavy metals. Many friends don’t know much about potassium phosphite. Let’s learn about potassium phosphite.
The effects of potassium phosphite
1. Disease prevention and bacteriostasis: rich in biostimulant phosphorous acid (containing +3-valent phosphite state phosphorus), which can stimulate crops to produce polyphenols. and reactive oxygen molecules (ROS), stimulate the activity of the defense enzyme system, and have good preventive and therapeutic effects on common fungal and viral diseases such as blight, downy mildew, root rot, late blight, etc. It is often used to improve crop disease resistance. The ability to resist adversity is greatly improved.
2. Safe and efficient: it can be transported in both directions through xylem and phloem, the nutrient absorption rate is improved, the utilization rate is high, the nutrients are pure, and there is no Hormones, no impurities, no clogging of sprinklers and drip irrigation capillaries, safer for roots, leaves, flowers and fruits.
3. Loose soil, increase permeability, improve the rhizosphere environment, which is conducive to healthy and robust growth of crops;
4. Promote root growth, plant growth, flower expansion and fruit production: use This product can promote the robustness of plants, effectively control the top advantage, avoid excessive vegetative growth of plants, make the crops full of flower buds, produce more and strong flowers, and significantly increase the fruit setting rate and quality, increasing production and income.
How to use potassium phosphite
1. Foliar spray: Fruit trees: dilute 1000-1200 times for foliar spray; vegetables: dilute 800-1000 times for foliar spray.
2. Flush application, dropper: 2.5-4 liters.
3. To control shoots and promote new and mature ripeness: dilute 300-500 times; for disease resistance and prevention, dilute 300-500 times.
4. To treat diseases (mixed pesticides) -500 is diluted; to prevent and control root and trunk diseases, dilute solvent dye manufacturers 200-300 times.
Precautions for potassium phosphite:
1. Potassium phosphite has good mixability and can be used together with copper preparations without causing precipitation or phytotoxicity.
2. Potassium phosphite can speed up the ripening of new and old fruits. It is safe to use during the spring shoot period and on young fruits, and will not cause phytotoxicity to young fruits.
3. Potassium phosphite has a significant effect in preventing ulcers, and the preventive effect is obvious when used alone. If the ulcer outbreak is severe, it is recommended to use it together with copper preparations.
4. Potassium phosphite is a high-concentration preparation. If there is crystallization, add water to dissolve it before use, and the effect will not be affected.
