- GA3 is not a substitute for fertilizers.
- After applying GA3, accelerated growth of plant tissues and organs increases nutrient and water consumption. Insufficient water or fertilizer may lead to yellowing leaves, weak plants, and failure to achieve yield goals.
- Use appropriate concentrations based on vegetable type and variety.
- Sensitivity to GA3 varies among vegetable species and cultivars.
- Excessive concentrations may cause:
- Excessive elongation, thin and fragile stems, pale/yellow leaves.
- Reduced edible quality, deformities, or plant death.
- Low concentrations may result in insufficient effects.
- For fruiting vegetables (e.g., cucumbers, tomatoes):
- Focus on spraying flowers and young fruits.
- Ensure uniform dipping/soaking to avoid uneven growth and deformed fruits.
- For leafy vegetables:
- Apply via foliar spraying across the entire plant.
- Adjust dosage based on plant size and density.
- Spray in the early morning or evening (after dew dries) for optimal leaf absorption.
- Usage varies by vegetable type and environmental conditions.
- Short-growth-cycle leafy vegetables: Apply during the early growth stage.
- Long-growth-cycle or bolting-prone vegetables (e.g., cabbage, spinach): Apply in the late growth stage.
- Vegetables harvested for flower stalks (e.g., broccoli): Apply earlier to promote bolting and branching.
- Temperature effects:
- High temperatures: GA3 acts faster but with shorter efficacy.
- Low temperatures: Slower response but prolonged efficacy.
- Seasonal adjustments:
- Winter: Apply earlier in cold conditions.
- Summer: Apply closer to harvest to maximize benefits.
- Mixing with other substances:
- Compatible: Acidic or neutral fertilizers/pesticides (e.g., urea for enhanced yield).
- Incompatible: Alkaline substances (e.g., lime, Bordeaux mixture).
