Active composition and physiological action
Hoshi supplies Gibberellic Acid (GA3), one of the most vital endogenous plant growth regulators.
Key physiological actions in treated crops:
- Active ingredient: Gibberellic Acid 0.001% Liquid (L).
- Cell elongation and division: Accelerates internodal elongation and vegetative growth during active developmental phases.
- Chlorophyll synthesis and photosynthesis: Enhances leaf surface area and green pigmentation, improving photosynthetic capacity.
- Flowering and fruit set: Alleviates physiological stress, preventing flower and fruit abscission in vegetables and fruit crops.
- Berry enlargement: Widely used in grape cultivation for bunch elongation and uniform berry development.
Target crops and optimal spraying stages
Hoshi is recommended across a wide spectrum of field crops, vegetables, and fruit orchards:
Key crop applications:
- Cotton: Applied during square formation and early boll development to reduce boll dropping.
- Paddy (Rice): Sprayed during active tillering and panicle initiation to boost effective tiller count and grain filling.
- Vegetables (Tomato, chilli, brinjal, okra): Applied prior to flowering and during early fruit development for uniform fruit sizing.
- Fruit orchards (Grapes, citrus, pomegranate): Sprayed at shoot elongation and fruit set stages for improved fruit retention and market grade.
Foliar application best practices and tank mixing
Apply Hoshi as a fine foliar spray during early morning or late afternoon hours when humidity is higher and stomata are open. Ensure proper soil moisture before spraying, as growth regulators require adequate plant hydration for optimal metabolic response. Follow manufacturer label instructions regarding dilution rates and compatibility before mixing with foliar micronutrients or crop protection products.
