Paclobutrazol Technical FAQ
Q: What is the recommended application rate for Paclobutrazol Technical?
A: The application rate varies depending on crop type and desired effect. For tree crops, typical rates range from 50-500 ppm. For ornamental plants, rates between 10-100 ppm are common. Always conduct small-scale trials before full application and follow local regulations.
Q: How does Paclobutrazol Technical work as a plant growth regulator?
A: Paclobutrazol Technical inhibits gibberellin biosynthesis, which reduces cell elongation and stem growth. This results in more compact plants with improved stress resistance and enhanced flowering potential. The compound is absorbed through roots and leaves, with systemic movement throughout the plant.
Application Guidelines
- Soil Application: Most effective method for long-term growth control
- Foliar Spray: Quicker effect but shorter duration
- Trunk Injection: Used for mature trees
- Timing: Apply during active growth periods for optimal results
Safety Information
| Aspect | Details |
|---|---|
| Acute Toxicity (Oral, Rat) | LD50 > 5000 mg/kg (Practically non-toxic) |
| Skin Irritation | Slightly irritating |

Paclobutrazol Technical FAQ
Q: What crops benefit most from Paclobutrazol Technical application?
A: Paclobutrazol Technical is particularly effective for fruit trees (mango, apple, pear), ornamental plants (azaleas, poinsettias), field crops (rice, wheat), and turf grasses. It helps control excessive vegetative growth, improve fruit set, and enhance stress tolerance in these plants.
Q: How long does Paclobutrazol Technical remain active in plants?
A: The residual effect typically lasts 3-6 months depending on application method, rate, and environmental conditions. Soil applications generally provide longer-lasting effects than foliar sprays. Effects may persist longer in woody plants compared to herbaceous species.
Handling and Storage
- Store in original container in a cool, dry place
- Keep away from food, feed, and beverages
- Wear protective gloves and eyewear when handling
- Avoid dust formation during handling
Compatibility
Paclobutrazol Technical is compatible with most commonly used pesticides and fertilizers. However, we recommend conducting a compatibility test before mixing with other products. Alkaline substances may reduce efficacy.
Paclobutrazol Technical FAQ
Q: What precautions should be taken when applying Paclobutrazol Technical?
A: Always wear appropriate PPE including gloves, goggles, and protective clothing. Avoid contact with skin and eyes. Do not eat, drink, or smoke during handling. Wash hands thoroughly after use. Follow all label instructions and local regulations regarding application rates and safety intervals.
Q: Can Paclobutrazol Technical be used in organic farming?
A: No, Paclobutrazol Technical is a synthetic plant growth regulator and is not approved for use in certified organic production systems under most organic standards worldwide. Organic growers should explore alternative growth management strategies.
