Widely used plant growth regulator DA-6 Diethyl aminoethyl hexanoate 98%TC
Widely used
Increase yield
Physical and chemical properties
Chemical name: Hexanoic acid, 2-(diethylamino) ethyl ester citrate
Molecular formula: C12H25NO2
Description: DA-6 is pure white scaly crystal, can dissolve in water easily, and can dissolve in polarity organic solvent such as ethanol, methanol and acetone etc. Stable in room temperature. Have slight amine smell.
Application
1. It can be directly diluted in water.It can use on crops. It can increase plants’ chlorophyll content, protein, nucleic acid, it can increase the speed of photosynthetic, it can accelerate the C/N metabolism and help plants to absorb water and fertilizers, increase the plant’s drought-resistant and cold-resistant-ability.
2. It can be compound with fertilizers, fungicides, insecticides.It can be compounded with N. P. Zn. Cu. Mn. Fe. Mo fertilizers etc. It can accelerate the crops to absorb fertilizers, and it can increase the fertilizer effect about 30%. It can save fertilizer about 10%.
3. It can be used on fruits, crops, flowers and vegetable etc.

The Usage and Dosage DA-6 Used on Different Crops | |||
Crops | Dosage (mg/L) | Method of use | Effects |
Wheat, Rice | 10-15 | Seed soaking 12-24h; spray once respectively in tillering stage,booting stage,filling stage
| Improve germination rate and cold-resistant capability,enhance dry-hot wind tolerance and seed setting rate; increase 1000-grain weight,increase yield. |
Cotton | 10 | Seed soaking 24h, spray once respectively in seedling stage,bud stage | Increase stress resistance, increase boll weight. |
Corn, sorghum | 8-15 | Seed soaking 6-12h; spray once respectively in seedling stage, jointing stage and heading stage. | Improve germination rate and seed plumpness, increase yield and promotecrop premature. |
Tobacco | 8-15 | Spray once in fast growing period, rosette stage and transplanting stage respectively | Make plant strong, improve rooting, increase leaf and better quality, then increase yield; increase stress resistance. |
Tea tree | 8-15 | Spray once in sprouting period of bud, and another after picked. | Improve germinating and quality, increase yield. |
Peanut | 10-15 | Spray once in initial time of flowering, pegging stage and pot-setting stage respectively | Increase flowering number and fruit bearing rate. High oil yielding rate, obviously yield increase. |
Soybean, mung bean | 12-16 | Spray once in seedling stage, initial time of flowering and pot-setting stage respectively | Increase flowering number and nodule bacteria nitrogen fixation ability. Increase yield and dry matter.
|
Radish,tuber mustard,burdock and other root vegetables | 12-16 | Seed soaking 4-6h; spray once respectively in seedling stage, fleshy root formulation stage expanding stage | Improve growth.Obviously increase yield.Make root tuber straight,thick and heavy. |
Potato,sweet potato, Chinese yam | 12-16 | Spray once in seedling stage, root tuber formulation stage and expanding stage | Increase yield and stress resistance |
Bean, hyacinth bean, pea, kidney bean | 5-10 | Spray once in seedling stage, full-bloom stage and pot-setting stage respectively | Good stress resistance,Increase bear pods rate, prematurity, increase yield. |
Tomato, eggplant, pepper, sweet pepper | 12-20 | Spray 2-3 times in seedling stage, initial time of flowering and fruit-setting stage | Increase yield and stress resistance obviously. Protecting flower and fruit. |
Chinese cabbage, lettuce, cabbage, spinach, celery | 6-10 | Spray 3-4 times in growth stage | Increase vegetative growth and yield, improve fibre, better taste. |
Watermelon, muskmelon, cantaloupe | 5-15 | Spray once in seedling stage, initial time of flowering respectively | Improve growth, fruit bearing rate, increase yield and content of sugar. |
Cucumber, white gourd, snake melon, zucchini | 5-10 | Spray once in seedling stage, initial time of flowering and fruit-setting stage respectively | Increase stress resistance, Improve fruit bearing rate and y ield obviously. |
Apple, pear, citrus, orange | 10-16 | Spray once in initial time of flowering and after fruit-setting stage and expanding stage respectively | Protecting flower and fruit, increase stress resistance; increase yield and quality. |
Grape, peach, plum, apricot, haw, loquat | 6-12 | Spray once in initial time of flowering and after fruitsetting stage and expanding stage respectively | Protecting flower and fruit, increase stress resistance; increase yield and quality. |
Litchi, longan | 10-15 | Spray 2-3 times between before blooming and after fruit setting | Protecting flower and fruit, increase yield. |
Banana | 15 | Spray once in bud stage and after bud broken | More fruit and even,increase yield. |
Sugarcane | 10-16 | Spray once in seeding stage, beginning of jointing stage and fast growth stage respectively | Increase available tillering, increase plant height, thick and content of sugar. |
Mushroom | 8-1 | Fructification,little fruit body stage and growth stage | Improve hypha activity and per mushroom growth speed, increase yield and quality obviously. |
