Product Application of Monopotassium Phosphite CAS#13977-65-6
High-Phosphorus and High-Potassium Fertilizer: Monopotassium phosphite is a fully water-soluble fertilizer rich in phosphorus and potassium. After application, it helps crops rapidly replenish phosphorus, potassium, and various trace elements. It can also support shoot growth, promote flower bud differentiation, improve fruit enlargement and early maturation, increase yields, and enhance crop quality.
Relief of Nutrient Deficiency Symptoms: It helps alleviate common symptoms of nutrient deficiencies in crops, including yellowing, deformities, small leaves, flower drop, and fruit cracking.
High Nutrient Availability: Monopotassium phosphite is less prone to fixation in soil, making it readily available for crop absorption and contributing to a high absorption and utilization rate.
Good Compatibility: It is less likely to antagonize trace elements and has a neutral pH. It can also be mixed with most pesticides and fertilizers.
Induction of Crop Defense Responses: When pathogens invade, potassium dihydrogen phosphite can stimulate seedling cells to produce lignin, increasing the thickness and hardness of cell walls and helping prevent pathogen penetration and spread.
Antifungal and Antibacterial Activity: Trivalent phosphorus ions have a strong inhibitory effect on fungi and bacteria and can help prevent and manage various plant diseases, including ulcer-related diseases.
Disease Management Applications: Registered as a fungicide in some overseas markets, potassium dihydrogen phosphite is used to help control various plant diseases, including downy mildew, powdery mildew, black spot, Phytophthora diseases, and root rot.
