Brassinolide Description

Natural brassinolide is a plant hormone that is widely used in agriculture to achieve optimal crop growth. It can be used as one of the best plant growth promoters for the production of agricultural products.

Natural brassinolide products enable seed treatment by increasing seed germination and improving seed vigor. It contributes to the growth of agricultural yields. It promotes sprout formation, fruit flavor, improves the coloration and good shape of the fruit.

It is suitable for food crops, cash crops, vegetables, and fruits to promote growth and increase yield, and has multiple functions such as strong rooting, growth promotion, seedling promotion, strong seedling, seedling preservation, greening of yellow and diseased leaves, promotion of fertilization, flower and fruit preservation, promotion of fruit expansion and early maturity, coordination of nutritional balance, drought resistance, cold resistance, salinity resistance, and enhancement of crop resistance.

Highlights of Dora Brassinolide

  • Increase crop stress tolerance, especially cold tolerance and drought tolerance.
  • Expands crop resistance to diseases and eliminates harmful chemical stresses from herbicides.
  • Helps crops grow stronger and release stress.
  • When mixed with herbicides, fungicides, and insecticides, it can be sprayed on crops to reduce and relieve chemical stress on crops.
  • Promotes growth. Ensures that all crops have amazing flowering and fruiting periods.
  • Suitable for all types of field crops, horticulture, and vegetables. Can be mixed with all types of pesticides/fungicides as well as PGR products.

Benefits & Application of Brassinolide

  • Promote the growth of root system and seedings
  • Promote vegetative growth
  • Promote reproductive growth
  • Increase crop stress resistance

At low temperature, drought, and salinity conditions, brassinolide can increase plant resistance to the adverse environment by enhancing the water absorption ability of plants, stabilizing the structure and function of the membrane system, sustaining higher metabolism, regulating the physiological environment in the cell, promoting normal physiological and biochemical metabolism.

Application of Brassinolide

Brassinolide —Potato

1. Soaking seed: Soaking seed with 0.01ppm Brassinolide, can promote seed germination.
2. At the early stage of tubers swollen, dilute 0.01% Brassinolide 3000times to spry, can promote the tubers swollen, increased yield 10%.


  • Promote the spring twig germination: At the stage of KMT, spray the trees with 0.04% Brassinolide 1000~1500 dilution + amino acid fertilizer, can solve the difficulties about the spring twig do not germinate. (Especially for the year spring drought and the trees had large quantity fruits last year)
  • Promote the floral organs developed fully: At the stage of flower bud, spray with 0.04% Brassinolide 1000~1500 dilution +liquid boron, can help pollination fertilizztion, and can reduce the phenomenon of “flower of inconclusive & stone fruit”.
  • Fruit retention: At the stage of the flower fade 80%, spray with 0.04% Brassinolide 1000~1500 dilution + Boron + Calcium, can have good effect on protecting young fruits, and preliminary prevention about the cracked fruit. 10~13 days later, spray 0.04% Brassinolide 1500 dilution + Calcium 2 times, can protect fruits and further prevention about the cracked fruit.
  • Improve coloring: At the stage of fruit maturity, spray 0.04% Brassinolide 1500 dilution 2 times, can promote fruit coloring, improve the fruit quality.

Period: Flowering, young fruit, expansion and coloring perio

Effect: Preserve flowers and fruits, significantly improve fruit set rate, uniform fruit size, good coloring, sweetening, early maturity and 25~40% yield increase, improve cold resistance.

Period: seedling, flowering, after fruiting, young fruit stage.
Effect: strong seedlings, disease resistance, resistance to adversity, increase flowering and fruit preservation, uniform and bright fruit, quality
Improve, early maturity, prolong harvesting period 15~30 days, increase yield 30~60%.

Period: Seedling, flowering and podding stages
Effect: Strong seedlings, good resistance to adversity, improved pod set rate, early maturity, extended growing period and harvesting period, 30~45% yield increase.

Period: first flowering stage, young fruit stage, fruit expansion stage.

Effect: Preserve flowers and fruits, significantly improve fruit set rate, uniform fruit size, good coloring, sweetening, early maturity and 25~40% yield increase, improve cold resistance.

Period: Seedling, Flowering, After Fruiting, Young Fruit Stage
Effect: strong seedlings, disease resistance, resistance to adversity, increase flowering and fruit preservation, fruit enlargement, sweet taste, quality. Quality improvement, early maturity, 20~35% yield increase.

Period: Seedling stage, rootstock formation stage Expansion stage
Effect: Strong seedlings, improved resistance, thicker rhizomes, early maturity, 30~50% yield increase.
