Prolibb – Gibberellic Acid 0.001% L
Prolibb is a plant growth regulator manufactured by MaxxGro Agrology Limited, containing Gibberellic Acid 0.001% as a liquid (L) formulation. It is used to increase the yield and quality of the crop produce in paddy (rice), applied at a growth stage that varies with variety duration — 20–25 days after transplanting (DAT) for short-duration varieties, 30–35 DAT for medium-duration varieties, and 40–45 DAT for long-duration varieties. Gibberellic acid is a natural plant hormone that promotes cell elongation.
Gibberellic Acid 0.001% L is also registered for use in sugarcane, cotton and groundnut. As a liquid formulation, Prolibb is diluted in water before spray application, and should be used strictly as per the crop, dose and timing recommendations on the approved product label.

- Contains Gibberellic Acid 0.001% as the active ingredient
- Formulated as a Liquid (L)
- PGR category product for growth regulation
- Registered use in paddy, among other listed crops
- Applied to enhance yield and quality of the produce
- Cell-elongation-promoting mode of action
Gibberellic acid (GA3) is a naturally occurring plant hormone belonging to the gibberellin class. It promotes cell elongation and cell division, stimulating stem elongation and influencing flowering and fruit/grain development. Applied at the recommended crop stage, it supports improved yield and quality of the harvested produce.
Prolibb (Gibberellic Acid 0.001% L) is diluted in the recommended volume of water and applied as a foliar spray in paddy at the crop stage appropriate to the variety’s duration, using standard knapsack or boom sprayers, following the approved product label.
- Use strictly as per the directions on the approved product label
- Wear appropriate personal protective equipment during mixing and spraying
- Avoid spray drift onto sensitive or non-target crops
- Keep out of reach of children and away from food, feed, and water sources
- Store in a cool, dry place in original packaging
