Potassium phosphite is not only a trivalent phosphorus-potassium fertilizer, but also a systemic fungicide that will not cause resistance after repeated use. It is both a fungicide and a high-potassium foliar fertilizer.
Characteristics of potassium phosphite
1. Fast absorption
Potassium phosphite can Through multi-directional transport through leaves, roots, xylem and phloem, the absorption rate of phosphorus is five times faster than that of phosphopeptides. EVA resin has a strong root-promoting effect, promotes plant robustness, effectively controls top dominance, and makes crop flower buds full. There are many flowers and fruits, which improves the fruit setting rate and fruit quality. The effect of using it on a variety of crops is much higher than that of potassium dihydrogen phosphate.
2. Disease resistance and prevention
Rich in biostimulant phosphorous acid (containing +3-valent phosphorous acid phosphorus), which can stimulate crops to produce polyphenols and reactive oxygen molecules ( ROS), stimulates the activity of the defense enzyme system, and has good preventive and therapeutic effects on common fungal and viral diseases such as downy mildew, root rot, and late blight.
3. Safe and efficient
It can be transported in both directions through xylem and phloem, with improved nutrient absorption rate, high utilization rate, pure nutrients, no hormones, no impurities, and does not block nozzles and drip irrigation capillaries. , safer for roots, leaves, flowers and fruits.
4. Systemic conduction
Potassium phosphite has a systemic up-and-down conduction effect, activating crops to produce polyphenols and reactive oxygen molecules, stimulating defense enzyme activity, and targeting internal invasion of crops. It has the effect of eradicating, treating and preventing diseases. Regular use can greatly improve the stress and disease resistance of crops, improve the transformation of long-term morbidity of crops, and improve the vitality of crops.
5. Improve the utilization of soil trace fertilizers
Potassium phosphite can release calcium, zinc, iron and other elements fixed in the soil, loosen the soil, increase permeability, and improve the root environment of crops. The roots are healthy and the plants are strong. It is not easy to antagonize trace elements and has a slightly acidic pH value. It can be mixed with most pesticides, copper preparations and fertilizers without causing precipitation or phytotoxicity. The mixability is particularly good.
6. High safety and mixability
Potassium phosphite can be mixed with a variety of copper preparations without causing phytotoxicity, and can also be mixed with a variety of pesticides, fertilizers, etc. It can be mixed and used, but cannot be used with strong alkaline preparations.
Notes
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 maturation of new shoots. It is safe to use during the spring shoot stage and young fruit stage 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. This product is a high-concentration preparation. If there is crystallization, add water to dissolve it before use, and the effect will not be affected.
