Physiological functions of Homobrassinolide
Homobrassinolides are steroid-based plant hormones that regulate cell division, cell elongation, and vascular differentiation.
- Stimulates rapid cell elongation and increases photosynthetic efficiency.
- Promotes pollen tube development, leading to improved pollination and fruit setting.
- Enhances synthesis of heat shock proteins and antioxidant enzymes to combat drought and moisture stress.
- Prevents premature drop of blossoms, buds, and developing pods.
Recommended crop stages and spraying instructions
Timing of application is critical to achieve optimal physiological responses in target crops.
- First spray: At the vegetative initiation or flower bud development stage to promote reproductive vigor.
- Second spray: At peak flowering or early fruit and pod formation stage to maximize fruit retention.
- Third spray: During fruit or grain enlargement to improve grain filling, size, and marketable quality.
- Compatible with most neutral pesticides and water-soluble fertilizers, but avoid combining with strong oxidizers.
Good agronomic practices with PGRs
Plant growth regulators supplement, but do not replace, balanced soil fertility and proper irrigation management.
- Ensure adequate soil moisture prior to spraying to allow systemic uptake through leaf stomata.
- Follow manufacturer package directions for water volume per acre to achieve uniform misting.
- Store containers in a cool, shaded environment away from direct sunlight and heat sources.

Common questions
What is the active molecule in Godrej Double?
It contains Homobrassinolide 0.04% EC, an advanced brassinosteroid plant growth regulator.
Can Godrej Double stop flower drop in chilli and cotton?
Yes, applying Homobrassinolide during the bud formation and early flowering stages significantly reduces flower and square drop.
Is Godrej Double a fertilizer or a pesticide?
It is a plant growth regulator (PGR), meaning it regulates plant biochemical pathways rather than acting as a direct nutrient source or pest toxin.
