JINMAI-Warm Sun® Cold Stress Protein Enhancer is a water-soluble fertilizer containing amino acids, designed to act as a cold-regulating protein promoter that helps crops resist low temperatures and frost damage. Its unique formula combines Amino Acids (100 g/L), B+Zn (20 g/L), biostimulants, and active extracts from deep-sea fish and seaweed to activate plant cold-resistance mechanisms.
Through plant cell signal induction technology, it stimulates the production of antifreeze factors, enhances cell vitality, and stabilizes cellular structures. The formulation strengthens cell walls, lowers the freezing point of cell fluids, and protects buds, leaves, flowers, and fruits during cold spells.

Key Features
Product Efficacy
⦁ Improves Cold and Frost Tolerance
Stimulates plant defense systems to withstand sudden temperature drops and frost events.
⦁ Protects Critical Growth Stages
Safeguards flower buds, young leaves, and fruits from low temperature injury.
⦁ Enhances Cell Vitality and Toughness
Strengthens plant cell walls and stabilizes membranes to maintain structural integrity.
⦁ Reduces Freezing Point of Cell Fluid
Increases osmotic concentration in plant cells, lowering the freezing point to prevent ice crystal damage.
⦁ Maintains Yield and Quality in Cold Conditions
Prevents cold-induced flower drop and fruit damage, ensuring higher marketable yield.
Applications
 | Citrus & Other Fruit Trees ⦁ Function: Protects flower buds and young fruits from frost ⦁ Expected Results: Higher fruit retention |
 | Grapes ⦁ Function: Maintains leaf and fruit health during cold spells ⦁ Expected Results: Consistent yield and quality |
 | Apples & Pears ⦁ Function: Reduces frost damage during flowering ⦁ Expected Results: More uniform fruit set |
 | Vegetables ⦁ Suitable Crops: Tomato, Pepper, Cucumber ⦁ Function: Prevents cold shock and slows stress recovery loss ⦁ Expected Results: Improved plant vigor |
 | Tea, Coffee, and Ornamentals ⦁ Function: Enhances cold resilience ⦁ Expected Results: Reduced winter injury |
Method Of Use
| Phenological Period | Dosage | Frequency |
Cold injury, frost injury, late spring cold, before buddin | Dilute 1000-1500 times | Foliar spray 1-2 days before the arrival of low temperature weather, spray 2-3 times continuously |
Note: The specific usage and dosage can be adjusted according to the differences in regions, crop types, yields, etc, under the advice of technical personnel.
Optimal Application Timing
Before expected cold weather or frost: Apply 3–5 days in advance to activate cold-resistance mechanisms.
During cold stress periods: Apply at intervals to maintain protection.
Post-frost recovery: Apply immediately after cold damage to aid cell repair and growth recovery.
Precautions
1. Mixing Order: When combining with other products, follow this sequence: water → this product → other products.
2. Compatibility: Compatible with most pesticides. Always conduct a compatibility test before first use.
3. Storage: Store in a cool, well-ventilated place, away from direct sunlight.
