6-Benzylaminopurine
Also known as: 6-BA, Benzyladenine
As a first-generation, highly effective cytokinin, 6-BA potently promotes lateral cell division and the sprouting of lateral buds, overcoming apical dominance to boost yields and fruit enlargement. Additionally, it significantly inhibits plant respiration and delays chlorophyll breakdown, making it a cost-effective choice for maintaining greenness and delaying senescence in crops, as well as for the post-harvest preservation of fruits and vegetables.

Key benefits
- Unlike growth-promoting substances that drive longitudinal elongation (such as gibberellins), 6-BA primarily stimulates the lateral division and expansion of plant cells. When applied during the early fruit development stage of crops like grapes, apples, and strawberries, it significantly increases fruit size, making it a common ingredient in fruit-enlarging fertilizers and formulations.
- Many crops exhibit strong apical dominance, meaning they grow primarily from the main stem without developing lateral branches. 6-BA can directly overcome this dominance and stimulate the sprouting of lateral buds.
- 6-BA possesses a highly stable chemical structure, remaining effective in both acidic and alkaline environments. This makes it ideal for combination with bulk water-soluble fertilizers, other plant growth regulators, or pesticides, creating a synergistic effect where the combined result exceeds the sum of the individual components.
Suggested dosage & application
- For Formulators & Manufacturers As a 98% Technical Grade concentration, this product must be formulated before broad field application. Solubility: 6-BA is insoluble in water. It dissolves readily in dilute hydrochloric acid or sodium hydroxide solutions, and organic solvents like ethanol or DMSO. It is commonly formulated into 2% SL or SP. Formulation Note: 6-BA is highly stable against heat, light, and pH fluctuations. It requires high-quality wetting agents or surfactants to prevent recrystallization when blended into complex clear liquid fertilizers. Synergistic Blends: Highly popular when co-formulated with GA4+7 (1:1 ratio) to create premium fruit-elongation and shape-improving commercial products (e.g., Promalin type).
- Reference Field Application Rates For standard foliar spraying, the general field application dosage ranges from 10 to 50 mg/L (ppm), depending on the specific growth stage and crop. To Promote Lateral Budding: Spray fruit trees or ornamental plants at 50 to 100 mg/L to break apical dominance, stimulating uniform side-branching. To Improve Fruit Set & Sizing: Apply a 10 to 20 mg/L spray during full bloom or early fruit development to accelerate cell division and maximize individual fruit size. To Extend Post-Harvest Shelf Life: Dip or spray harvested green vegetables (like broccoli or celery) with a 5 to 10 mg/L solution to delay chlorophyll breakdown and keep crops fresh during transport. To Ensure Optimal Efficiency: Direct the spray primarily at the growing points, blossoms, or young fruits, as 6-BA has limited systemic mobility within the plant tissue.
