Krivita Xxl (Paclobutrazol 40% SC) Plant Growth Regulator
The advanced "Source-to-Sink" optimizer for Mango, Onion, and Tuber crops.
Krivita Xxl is a high-concentration (40% SC) Plant Growth Regulator (PGR) designed to stop unwanted vegetative growth and redirect plant energy toward fruit and root development. It is the industry standard for stopping "alternate bearing" in mangoes and boosting bulb size in vegetable crops.
Best For: Mango orchards, Onion, Garlic, Potato, and Groundnut farming.
Why Choose This Product? Key Benefits
-
⏱️
Early Flowering & Ripening: Induces flowering 2-3 weeks earlier, helping you catch premium early-market prices.
-
🛡️
Disease & Fungal Defense: Creates thicker leaves and stronger cell walls, offering incidental protection against fungi and pests.
-
⏳
Stops Alternate Bearing: Ensures Mango trees yield fruit every year by controlling post-harvest vegetative flushing.
-
🌧️
Drought Tolerance: Helps plants survive water stress by regulating stomata (pores) and reducing water loss.
-
🌿
Bigger Bulbs & Roots: Redirects nutrients from the leaves to the underground tubers/bulbs (Onion, Garlic, Potato).

How It Works: Mode of Action
Krivita Xxl acts as a metabolic re-partitioning agent. Instead of allowing the plant to waste energy on excessive height and leaves, it forces the plant to focus on reproduction and storage.
- Blocks Vertical Growth: It inhibits the production of Gibberellins (growth hormones), stopping unnecessary shoot elongation and "luxury" leaf growth.
- Redirects Energy (Source-to-Sink): By stopping upward growth, the sugars and carbohydrates produced by the leaves are sent down to the fruits, seeds, and bulbs.
- Hormonal Balance: It increases Cytokinins (greener leaves) and Abscisic Acid (ABA), which helps the plant resist drought and stress.
This results in a compact, darker green plant with a massive root system and high-quality produce.
Target Crops & Pests
| Crop | Target Benefit / Issue Solved |
|---|---|
| Mango | Control of alternate bearing, induction of early flowering, canopy management. |
| Onion & Garlic | Prevents "bolting" (flowering), increases bulb diameter, improves storage quality. |
| Potato & Groundnut | Prevents lodging (falling over), increases tuber number and starch content. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Tree Age" for Mango and "Dose per Acre" for vegetables for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre OR Tree) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Mango (7-15 Years) | 8 - 15 ml per Tree | 2 - 3 L per Tree | Mix in Soil | >90 Days |
| Mango (16-25+ Years) | 16 - 40 ml per Tree | 3 - 10 L per Tree | Mix in Soil | >90 Days |
| Onion / Groundnut | 30 - 80 ml / Acre | 150 - 200 L | ~0.2 - 0.5 ml | See Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Mango application is typically done post-harvest (Oct-Jan).
How to Apply: Best Practices
- Timing (Mango): Apply strictly Post-Harvest (Sept-Jan) or 90-120 days before expected flowering.
- Method (Mango): Use the "Collar Drench" method. Dig a small trench around the trunk base and pour the solution. The soil must be moist.
- Timing (Vegetables): Apply 45-60 days after transplanting or when the crop begins bulbing/flowering.
- Safety: Always wear PPE (gloves, mask, goggles). This product affects hormones and fertility; handle with extreme caution. Wash hands thoroughly after use.
Frequently Asked Questions
1. How is Krivita Xxl different from standard Paclobutrazol?
Krivita Xxl is a 40% SC concentrate, whereas standard products are often 23%. This means you use less volume for the same impact, and the Suspension Concentrate (SC) technology ensures better absorption and stability.
2. Does it help with Alternate Bearing in Mango?
Yes. By applying it in the "Off-year" (post-harvest), it stops vegetative flushing and forces the tree to store carbohydrates, enabling flowering the following season.
3. Can I spray this on the leaves of Mango trees?
No. For Mango, soil application (Collar Drench) is far more effective because the chemical moves up through the roots (xylem). It does not move down from leaves to roots efficiently.
4. What happens if I overdose?
Overdosing can cause "stunting" where the tree stops growing, and flower stalks become too short (compact panicles). Always adhere to the age-specific dosage.
5. Is it useful for Onion and Garlic?
Absolutely. It stops the plant from bolting (flowering prematurely) and pushes all energy into making the bulb bigger and heavier.
