Physical and Chemical Properties
1. The appearance of the active drug is a colorless viscous transparent liquid with aromatic smell.
2. Soluble in methanol, ethanol and acetone, insoluble in water, stable in acidic, neutral and alkaline media.
Function of Propyl dihydrojasmonate
1. It is a synthetic plant growth regulator, similar in structure to jasmonic acid, a natural plant regulator commonly found in vascular plants, with the same function and similar action pattern, and harmless to the environment.
2. It can promote the synthesis of endogenous S-ABA inducers, promote ethylene production and promote fruit ripening.
3. It can catalyze the synthesis of anthocyanidin and carotene, enhance the accumulation of anthocyanidin and improve the antioxidant capacity of fruits.
4. It can induce the expression of plant resistance genes, arouse the active defense of plants and enhance their resistance to adversity.
Storage:It should be stored in a well-closed container at low temperature, keep away from moisture, heat and light.
Function characteristics
1. Can increase the grape ear, grain weight and soluble solid content, and promote the color of fruit surface;
2. It can promote healthy ripening of apples, perfect coloring, and effectively improve fruit quality;
3. Improve cold and drought resistance and antiviral ability of wheat, maize and rice;
4. It can be mixed with micro fertilizer and potash fertilizer, and mixed with brassica to reduce the amount and increase the efficiency;
5. After PDJ treatment, the content of anthocyanidin in fruit increased significantly, which promoted coloring and early fruit ripening;
Compared with abscisic acid and ethephon, it does not produce deciduous fruit, and promotes healthy ripening of grapes, cherries and apples in advance with perfect coloring.
Usage of Propyl dihydrojasmonate
It is suitable for jujube, citrus, grape, strawberry, apple and other crops. It can be sprayed on the leaf surface of 50PPM during the fruit expansion period with remarkable effect.
Comparison of Several Grape Colorants on the Market
Variety | S-ABA | DA-6 Ethephon | PDJ |
Usage Time | Only use when grapes have begun to color (after 10%) | Only use when grapes have begun to color | Only use when grapes have begun to color |
Advantage | 1. Color faster, does not affect the photosynthesis of leaves; 2. Does not reduce the sugar content of fruit; 3. Fruit does not become soft. | 1. Fast coloring (see results in 7 days); 2. Whole leaf spray, easy to use; 3. Color is more uniform, the price is cheap. | 1. Can spray the whole plant, color faster and uniform; 2. Can improve the sugar content, improve the fruit quality; 3. It does not cause yellowing of the leaves and does not cause cracking; 4. Promotes both ripeness and coloration. |
Disadvantage | 1. Belongs to pesticide; 2. an fruit surface treatment only; 3. Overuse can easily cause fruit shedding; 4. Improper use will cause uneven coloring; 5. Too much color will turn purple and will not promote ripeness. | 1. Belongs to pesticide; 2. Easy to cause leaf aging, use too early or too many times; 3. easy to cause water jar disease; 4. Excessive concentration can also cause granulation. | Current use cost is low. |
