Potassium phosphite is a new multi-purpose special phosphorus and potassium fertilizer that is environmentally friendly, reusable and non-drug resistant. In the process of using it, we need to understand what the function of potassium phosphite is. What should we pay attention to when using potassium phosphite? What are its characteristics? Let’s take a look together!
Uses of potassium phosphite
1. Disease prevention and bacteriostasis: rich in biostimulant phosphorous acid (Containing +3-valent phosphite phosphorus) can stimulate crops to produce polyphenols and reactive oxygen molecules (ROS), stimulate the activity of defense enzyme systems, and treat common fungal diseases, downy mildew, root rot, late blight and other fungal diseases. It has good preventive and therapeutic effects on viruses and viral diseases. If used regularly, the disease resistance and stress resistance of crops will be greatly improved.
2. Safe and efficient: It can be transported in both directions through xylem and phloem, and the nutrient absorption rate is improved, and the utilization rate is high. The nutrients are pure, no hormones, no impurities, no clogging of nozzles and drip irrigation capillaries, and good for roots, leaves, Flowers and fruits are safer.
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.
It can be widely used in economic crops and field crops such as fruit trees, vegetables, fruits, Chinese medicinal materials, seedlings and flowers in the north and south.
Characteristics of potassium phosphite
1. Fast absorption
Potassium phosphite can be transported in multiple directions through leaves, roots, xylem and phloem, and the absorption speed is faster than It is 5 times more phosphorus than phosphopeptides. It has a strong root-promoting effect, promotes plant robustness, and effectively controls the top advantage. It can meet the timely supply of nutrients at the top of fruit trees during the fruiting period, avoid plant overnutrition, and make crops full of flower buds and flowers and fruits. More, improve 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, which is three times as effective as potassium dihydrogen phosphate.
2. Disease resistance and prevention
In potassium phosphite, phosphorus is a +3-valent phosphorus and potassium fertilizer, and it is a systemic fungicide that triggers plant cells Molecular reactions within the plant exert its bacteriostatic effect by activating the plant’s own immune system and defense mechanisms. The +3-valent P modifies the fungal wall and inhibits further proliferation by inhibiting spore formation, thus controlling the disease and its further spread.
Potassium phosphite is often used as a new type of bactericidal and environmentally friendly fertilizer. In the application of citrus, potassium phosphite has many functions: it can be quickly absorbed by leaf spraying and flushing application, and can quickly replenish phosphorus and potassium fertilizers; it can regulate the closing of plant stomata; it can regulate the growth effect and can control shoots before crop growth. It controls growth and promotes flowering; it promotes the ripening of new shoots and the greening of young fruits; it is systemic and can be transmitted up and down in the plant, protecting, treating and eradicating the left and right brains, and can be mixed with other compounds (including copper preparations).
3. 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 eradication, treatment and preventive effects on infected 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. Leaf spraying, flushing application, and drip irrigation absorb quickly, and can quickly replenish phosphorus and potassium fertilizers with ultra-high absorption efficiency. Promote root growth, promote fruit color change, increase sugar content, promote flower bud differentiation, and promote photosynthesis.
4. Improve soil micro-fertilizer utilization
Potassium phosphite is used at the roots (root irrigation, drip irrigation, root drenching, flushing) to release calcium, zinc, and iron fixed in the soil. and other elements, loosen the soil, increase permeability, improve the rhizosphere environment, healthy development of crop root systems, and strong plants. It is not easily fixed in the soil, and at the same time releases iron, zinc, calcium and other elements solidified in the soil, which are easy to be absorbed and have a high absorption and utilization rate. 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. It has the effect of regulating growth and can control shoot growth and promote flowering in the early stages of crop growth.
5. 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. Potassium phosphite can be mixed with common medium and trace element fertilizers (calcium sugar alcohol, chelated calcium, etc.). Potassium phosphite can accelerate the maturity of new shoots. It is safe to use in the spring shoot stage and young fruit stage and will not harm young shoots. The result is phytotoxicity.
How to use Cabot
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 ripening: dilute 300-500 times; use this product to resist and prevent diseases, dilute 300-500 times.
4. Treat diseases (mixed pesticides) -500 diluted; use this product to prevent root and trunk diseases by diluting 200-300 times.
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 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 single-use preventive effect is obvious. If…In serious ulcer outbreaks, it is recommended to use it with copper preparations.
Rubber antioxidant 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.
