Agreenco Brand Hydrogen Cyanamide 50%SL
High Efficient Dormancy breaking for Grape, apple, peach, blueberry.
1.Brief for Agreenco Brand Hydrogen Cyanamide 50%SL:
Fruit quality: After treatment with Hydrogen Cyanamide , colored grape varieties have deeper coloring, better appearance, high sugar to acid ratio, and increased soluble solid content.
Hydrogen Cyanamide can be used to break the dormancy period of grape and deciduous fruit crops, promote their early germination, flowering, fruiting, maturity, and increase single fruit weight and yield. In plants, Hydrogen Cyanamide is rapidly metabolized and converted into the carbon source required for plant growth. Extremely low residue during maturity. It has no adverse effects on fruit quality and is an excellent plant growth regulator for producing green fruits.
Previous studies have shown that some sweet cherry varieties or other tree species cultivated in warm winter regions have a longer flowering period than when planted in temperate or cold regions. This phenomenon is caused by low winter low temperature accumulation and can be offset by the application of Hydrogen Cyanamide.
In order to compensate for the insufficient accumulation of cooling demand, Hydrogen Cyanamide has been widely used as an effective dormancy breaking agent in the production of deciduous fruit trees such as grapes, kiwifruit, apples, and peaches. Studies have shown that spraying Hydrogen Cyanamide on fruit trees 2-5 weeks before natural germination can promote early and consistent germination, increase the number of
flowers and fruits,advance the flowering and ripening stages, and improve fruit quality.
2.Physical and Chemical Characteristics of Agreenco Brand Hydrogen Cyanamide 50%SL:
Molecular Formula:NH2CN.
CAS No.:420-04-2
Solubility: Easily soluble in water, ethanol, etc., slightly soluble in carbon disulfide.
Stability:Transformed into dicyandiamide at 122 ºC, it is an isomer of carbodiimide (H2NCNHN=C=NH). Easy to polymerize, three identical cyanamide molecules can combine to form a trimeric compound melamine.
The content of Hydrogen Cyanamide is above 51%, the pH is within 5, and the content of dicyandiamide is controlled within 1.2%. After 15 days of standing, filter. Transport in a freezer at around 5 ºC, preferably refrigerated at 5-10 ºC for storage.
3.Mode of Action:
Agreenco Brand Hydrogen Cyanamide 50%SL is actually an inhibitor of catalase (CAT). After exogenous application, it can lead to an increase in the hydrogen peroxid content in the buds.
Hydrogen peroxid plays a dual role in plants, and at low levels, it is a sensitive signaling molecule that reflects external pressure, including dormancy release.
When the content of continues to increase, it becomes metabolic waste, which can damage the membrane structure of cells, various proteins, DNA, etc
Due to the inhibition of catalase by Hydrogen Cyanamide, in order to eliminate the adverse effects of hydrogen peroxid, the activity of peroxidase (POD) will instead increase, leading to a shift in respiration towards the pentose phosphate pathway. This shift causes an increase in a deoxyribonucleotide, which is necessary for improving the metabolism of dormant bud tissue and ultimately triggering germination.
In fact, the essence of grape cooling is also to inhibit the activity of catalase, and exogenous application of Hydrogen Cyanamide can accelerate and supplement this process, so it can replace a portion of the cooling requirement.
4.Dosage of Agreenco Brand Hydrogen Cyanamide 50%SL:
Usage time: Generally during the middle or late stages of dormancy, on sunny days, with the best effect around 20 days before germination.
Concentration used: Hydrogen Cyanamide 50%SL , diluted 20-25 times
Usage: Smear or spray. When smearing, except for 1~2 buds on the top (keep the apical dominance), the rest of the buds should be treated with medicine;
Spray from top to bottom, throughout the entire tree, do not repeat or miss spraying, generally speaking, the application effect is better.
5.Applications of Agreenco Brand Hydrogen Cyanamide 50%SL:
(1):Hydrogen Cyanamide 50-51%SL:
For breaking dormancyforgrape,apples,peach,blueberry,etc.
(2): Hydrogen Cyanamide 20%SL: Defoliant;
6.Precautions of Agreenco Brand Hydrogen Cyanamide 50%SL:
1). Before using Hydrogen Cyanamide, try to keep the branches moist as much as possible. You can spray clean water in advance or water them after use to prevent bud burning (when the soil is relatively moist, you can also water them again 10 days after using the medicine);
2).The appropriate temperature for use should be 10-20 ºC. If it exceeds 20 ºC, it decomposes quickly and loses its efficacy;
3).Hydrogen Cyanamide has certain toxicity, and many people are allergic. It is best to wear gloves and masks during operation. After operation, wash your eyes and mouth with clean water, and clean exposed areas such as face and hands with soap.
4). Do not repeat spraying or use at excessive concentrations, as this can actually deepen the dormancy of buds or even cause them to die;
5).Don't overly promote early, as Hydrogen Cyanamide can only replace some of the required cooling capacity.
7. Packing: 20liters/ 25Liters/ 200Liter/Drum;1000L/IBC Drum; or as per customers' requested.
