A dual-action, high-concentration suspension concentrate designed to optimize mechanical harvesting in intensive cotton cultivation global networks.
Thidiazuron (360g/L) functions as a synthetic phenylurea plant growth regulator exhibiting potent cytokinin-like biological activity. Upon foliar absorption, TDZ triggers rapid synthesis of endogenous ethylene while simultaneously suppressing auxin transport across the leaf petiole. This hormonal imbalance accelerates the formation of a distinct abscission layer at the leaf base, leading to green leaf drop without causing premature tissue necrosis.
Diuron (180g/L) acts as a targeted Photosystem II (PSII) herbicide by blocking electron transport at the QB-binding niche of D1 protein within chloroplast membranes. When combined with TDZ at a 2:1 ratio, Diuron generates controlled reactive oxygen species (ROS) stress, accelerating leaf senescence under cooler ambient temperature conditions where standalone TDZ activity typically declines.
The co-formulation of 360g/L TDZ and 180g/L Diuron yields a robust physiological synergy. While TDZ stimulates petiole separation, Diuron stops carbohydrate synthesis, preventing regrowth of young shoots (suckers). This dual action guarantees over 95% leaf drop within 7–10 days, allowing clean mechanical picking and reducing seed cotton trash content significantly.
Engineered via wet sub-micron milling technology to deliver ultra-stable rheology, instant dispersion, and zero nozzle clogging.
Thidiazuron technical active ingredient exhibits low water solubility and a tendency toward crystal growth in liquid medium. China high-tier suppliers utilize specialized polycarboxylate block-copolymer dispersants combined with modified naphthalene sulfonate condensates. Controlled wet bead milling ensures particle size distribution with D90 < 2.5 microns, completely suppressing crystal lattice growth (Ostwald ripening) even under extreme thermal storage conditions (-5°C to 54°C).
The SC matrix integrates organosilicone-modified wetting agents that drop liquid surface tension below 28 mN/m. This guarantees rapid stomatal penetration and spread across waxy cotton leaves within 30 minutes of spray application. Enhanced rainfastness protects the investment against unexpected rainfall, ensuring maximum chemical absorption by crop leaves.

Operational instructions for max defoliation efficiency, minimal green leaf trash, and rapid cotton boll opening.
Apply when natural boll opening reaches 60% to 70% across the field and the top harvestable boll is mature (firm to squeeze, seed coats turning brown). Early application can reduce fiber length and seed weight, whereas delayed application reduces defoliation efficiency prior to frost.
Standard field application rate ranges from 300 mL to 450 mL per Hectare (approx. 20–30 mL per 667m²), diluted in 300–450 L of water for ground boom sprayers or 30–50 L for aerial UAV drone spraying systems.
Use fine-to-medium droplet spray nozzles ( hollow cone or flat fan) maintaining 3.0 to 4.0 bar pressure. High foliage canopy penetration is critical; ensure uniform coverage of lower and middle leaf strata for complete defoliation.

Standalone Thidiazuron WP formulations require high daytime temperatures (> 20°C) to function efficiently and are prone to dust hazard during mixing. The co-formulated SC liquid version (360g/L TDZ + 180g/L Diuron) leverages Diuron's photosynthetic inhibition to break low-temperature dormancy. This allows reliable defoliation down to 12°C–15°C while offering dust-free handling, better leaf adherence, and zero nozzle abrasion.
Thidiazuron stimulates ethylene production and blocks auxin transport, initiating natural petiole leaf drop. Concurrently, Diuron halts photosynthetic carbon fixation within the plant's chloroplasts. Without carbohydrate generation, dormant lateral buds cannot sprout into new green shoots (regrowth), maintaining cleaner seed cotton during mechanical stripping or picking.
The formulation has a guaranteed shelf life of 2 years under standard ambient conditions. It should be stored in original sealed containers in a cool, dry, well-ventilated warehouse away from direct sunlight, freezing temperatures, food, and animal feed. Shaking or agitating drums prior to bulk field mixing is recommended after prolonged storage.
Yes. Awiner Biotech provides complete registration support packages including Certificate of Analysis (COA), Certificate of Origin (COO), ICAMA registration certificates, GLP six-toxicology report summaries, physical-chemical properties reports, and product risk evaluation data required by agricultural authorities across South America, Central Asia, Eastern Europe, and Africa.
Key factors include crop physiological maturity (boll open rate > 60%), ambient daily temperatures, relative humidity during application, spray volume coverage, and crop nitrogen status. Over-fertilized, lush green cotton crops may require higher dosage or tank-mixing with Ethephon to achieve complete defoliation.
