Usage and dosage:
1.Applicable to all kinds of Cash crop and field crops.
2.The application of 30-60ml foliar spraying per mu of field crops can increase the weight of 1000 grains, increase yield, and resist stress.
3.Cucurbitaceae crops are sprayed with 1000-1200 times dilution on the leaf surface to prevent mildew and Powdery mildew and fungal diseases.
4.Spraying diluted 1000-1200 times on the leaves of nightshade crops to prevent late blight.
5.Spraying 800-1200 times on the leaves of citrus and orange crops to prevent ulcers and increase sweetness and color. 

Using effect:
1.Inducing crops to produce resistant toxins and disease related proteins, containing+3 valent phosphorus, inducing crops to emit disease resistance signals, which are transmitted to cells that have not yet been attacked, activating the defense system, and having protective, therapeutic, and eradication effects. It can be mixed with other compounds.
2.When pathogenic bacteria invade, Phosphorus acid can induce seedling cells to produce lignin, increase the thickness and hardness of cell wall, and prevent the invasion and expansion of bacteria.
3.Trivalent phosphorus ions have strong immune effects on fungi and bacteria, and have preventive immune effects on most diseases such as ulcers.

4.Control and strong branch , improve quality.It is a fully water-soluble fertilizer with high phosphorus and potassium. After application, crops can quickly supplement phosphorus and potassium and various trace elements, which can control the shoots of crops, promote flower bud differentiation and swelling, advance maturity, increase yield and improve quality.
