Prohexadione Calcium
Calcium cyclamate is a new plant growth regulator. The synthesis of gibberellic acid can be inhibited by leaf absorption of plant seeds and roots,. It can shorten the stem elongation of many plants. In addition, the dry matter accumulation, quality improvement and yield increase of the underground tuber and tuber crops, and the slight control on some fruit trees have a good effect on fruit color conversion and ripening. Compared with the triazole retarders widely used at present, calcium cyclamate has no residual toxicity to rotation plants and no pollution to the environment, so it is possible to replace triazole retarders and has a wide application prospect.

Propargyl Alcohol
Propynol, also known as 2-propyn-1-ol, is an organic compound with the chemical formula C3H4O. It is a colorless and transparent liquid and is highly toxic. It is used as a rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, etc. Organic synthesis intermediates, solvents, stabilizers for chlorinated hydrocarbons. It can be used alone as a corrosion inhibitor, and it is best to be compounded with a substance that produces a synergistic effect to obtain higher corrosion inhibition efficiency. For example, in order to increase the corrosion inhibition effect of alkynol in dilute sulfuric acid solution, it is recommended to add sodium chloride, potassium chloride, calcium chloride, potassium bromide, potassium iodide or zinc chloride.
Propiconazole
Propiconazole is a kind of protective and therapeutic effect of systemic fungicide, and can be absorbed by the root, stem, leaf, and can quickly in the plant body upward transmission, kill pathogenic bacteria in the body, has good control effect of banana leaf spot disease.
Propylene Carbonate
Propylene Carbonate (often abbreviated PC) is an organic compound with the formula C4H6O3. It is a carbonate ester derived from propylene glycol.This colorless and odorless liquid is useful as a polar, aprotic solvent. Propylene carbonate is chiral but is used exclusively as the racemic mixture. Propylene carbonate is used in a variety of syntheses and applications as a polar, aprotic solvent.
