Industrial-grade phytohormones optimized for tropical climate resilience, yield enhancement, and crop cycle management.
Sri Lanka's agricultural sector stands at a critical juncture. From the high-altitude tea plantations of Nuwara Eliya, Badulla, and Kandy to the intensive paddy cultivations of Polonnaruwa and Anuradhapura, modern farming operations are facing dual pressures: mitigating climate-induced thermal stress and optimizing physiological crop efficiency under changing regulatory dynamics.
Plant Growth Regulators (PGRs)—including brassinosteroids, triazoles, cytokinins, auxins, and gibberellins—are no longer optional inputs; they are precision biochemical tools essential for yield stability, flowering synchronization, drought resistance, and post-harvest shelf-life extension in export-bound commodities like Ceylon Tea, mangoes, pineapple, and spice crops.
Tailored plant physiological regulation engineered for the Wet, Intermediate, and Dry Agro-Ecological Zones of Sri Lanka.
In Up-Country and Low-Country tea estates, Brassinolide 0.1% SP and Cytokinin 6-BA (6-Benzylaminopurine) stimulate dormant vegetative buds, accelerating bud-break following pruning cycles and enhancing green leaf weight during critical plucking seasons.
In the dry zone (Kurunegala, Dambulla, Hambantota), Paclobutrazol 25% SC / 15% WP is widely utilized for off-season flower budding in commercial mango orchards (e.g., Tom EJC, Willard), controlling excessive vegetative flushing and regulating flowering timelines.
During the Yala and Maha cultivation seasons, high rainfall and wind can lead to severe lodging in paddy rice. Low-dose Paclobutrazol combined with Gibberellic Acid (GA3) optimizes internode length, increases stem thickness, and maximizes panicle size.
S-Abscisic Acid (S-ABA 98% TC) acts as an endogenous signaling molecule regulating stomatal closure during prolonged dry spells, reducing transpiration loss in coconut plantations, field vegetables, and cash crops in Sri Lanka's dry zone.
For commercial nurseries producing Hevea brasiliensis (Rubber) and horticultural export crops, Indole-3-Butyric Acid (IBA 98% TC) guarantees high-rooting efficiency, adventitious root initiation, and robust sapling establishment.
Thidiazuron (TDZ 50% WP / 95% TC) offers powerful defoliation properties and works as a dominant cytokinin derivative for plant tissue culture laboratories operating across Sri Lankan agricultural research centers.
Industrial parameters tailored for chemical importers, distributors, and large-scale estate plantations in Sri Lanka.

Expert insights addressing key technical, logistical, and commercial inquiries for Sri Lankan importers and agrochemical distributors.
Natural Brassinolide 0.1% SP applied at a dosage of 0.01–0.03 ppm combined with 6-Benzylaminopurine (6-BA 2% SP) is highly effective in breaking apical dominance, increasing active flush points, and accelerating recovery after pruning, yielding up to 15-22% increase in green leaf weight.
Paclobutrazol works by blocking gibberellin biosynthesis within the vegetative shoot tips. Applied as a soil collar drench 2 to 3 months prior to expected flowering, it forces the tree to shift energy from vegetative growth to floral differentiation, enabling off-season harvesting when market prices peak.
Sri Lanka’s Customs and Department of Agriculture require an import permit issued under the Control of Pesticides Act No. 33 of 1980. Awiner Biotech provides complete registration support including Certificate of Analysis (COA), Certificate of Origin (COO), SDS, and complete lab analytical reports.
When stored in original unopened containers under dry, shaded conditions between 15°C and 30°C, our liquid formulations (SC/SL) maintain stability for 2 years, while solid technical powders (TC/WP/SP) remain stable for up to 3 years.
