Structural Formula

Function

1.Induced flowering: salicylic acid is related to the induction of flowering.There are dozens of plants promoted by salicylic acid, providing a new idea for the physiological regulation of horticultural plants.
2．Promoting high quality and high yield of crops: low-concentration salicylic acid can significantly enhance anabolism, increase grain’s  weight ａnd number, increased yield and improved quality.
3．Improve the resistance and tolerance of crops to adversity: most plants, including rice, corn, wheat, rape, tomato, vegetable, bean, cucumber, garlic, soybean, sugar beet and tobacco, etc., have better resistance to salt ,drought and cold after the application of salicylic acid.
4.Improve the storage of fruit: after salicylic acid treatment, the cell membrane permeability and malondialdehyde content decreased;the respiration rate decreased significantly;the fruit senescence was delayed. Similar results were observed in studies on fruits such as pear, peach and citrus. This may be related to the inhibition of ethylene production. The production of ethylene was observed by salicylic acid treatment, which proved that the inhibitory effect of salicylic acid was related to salicylic acid concentration, temperature and physiological state of potato block.
5.Salicylic acid has a certain effect on the preservation of flowers, and can significantly inhibit the growth of bacteria

Storage

It should be stored in a cool, ventilated and dry place, far away from the fire source and heat source.Keep it separate from explosive products and oxidizing agents. Avoid light.
