JINMAI-Yiweipu® Ferrous Iron Fertilizer with Sugar Alcohol is a specialized liquid micronutrient fertilizer formulated to provide crops with a readily available source of ferrous iron (Fe⊃2;⁺). The formula contains 60 g/L iron, 100 g/L sugar alcohol, glucan and functional additives, helping improve iron availability and support efficient nutrient utilization.
Designed primarily for foliar application, this liquid iron fertilizer can be rapidly absorbed by plant leaves and utilized by crops during periods of active growth. It is particularly suitable for crops showing symptoms associated with iron deficiency, including interveinal chlorosis, pale or yellow young leaves, reduced plant vigor and poor shoot development.
Unlike conventional iron fertilizers that may have limited availability under certain growing conditions, the formula combines ferrous iron with sugar alcohol and functional additives to help maintain iron availability and improve the efficiency of foliar nutrition.

Iron deficiency is commonly associated with yellowing between leaf veins, especially on young leaves. Timely foliar application can help provide supplemental iron and support the recovery of normal leaf coloration.
Iron is closely associated with chlorophyll synthesis and photosynthetic metabolism. Maintaining adequate iron nutrition helps crops sustain healthy green foliage and productive photosynthetic activity.
By supplying additional iron during periods of deficiency, the product helps support healthier foliage, active shoot development and overall crop vigor.
Iron deficiency can affect young tissues and developing shoots. Supplemental foliar iron can help meet the increased micronutrient demand of actively growing crops.
The combination of ferrous iron, sugar alcohol and functional additives is designed to improve the efficiency of foliar micronutrient nutrition.
The addition of β-1,3 glucan provides a functional component that supports natural crop defense responses and helps plants maintain vitality under unfavorable growing conditions.
 | Fruit Trees⦁ Suitable Crops: Citrus, Apple, Pear, Cherry, Grape ⦁ Main Purpose: Iron deficiency and leaf chlorosis management ⦁ Expected Effect: Supports greener foliage, improves leaf color, and promotes healthy shoot and canopy development |
 | Berry & Small Fruit Crops⦁ Suitable Crops: Strawberry, Blueberry, Other Berries ⦁ Main Purpose: Foliar iron supplementation ⦁ Expected Effect: Supports vigorous vegetative growth and healthy leaf development |
 | Vegetable Crops⦁ Suitable Crops: Tomato, Pepper, Cucumber, Melon, etc. ⦁ Main Purpose: Iron deficiency during rapid growth ⦁ Expected Effect: Helps maintain healthy green foliage and supports strong plant vigor |
 | Leafy Vegetables⦁ Main Purpose: Iron supplementation ⦁ Expected Effect: Promotes deep green leaves and uniform growth |
 | Field Crops⦁ Main Purpose: Corrective micronutrient nutrition ⦁ Expected Effect: Helps maintain crop vigor under conditions of low iron availability |
Method | Phenological Period | Dosage | Frequency |
| Foliar Spray | Early vegetative growth, chlorosis correction | 0.5-1 L/ha (Dilute 1200-1500 times) | Every 7-10 days |
| Continuous vegetative growth | 0.8-1.2 L/ha (Dilute 1200-1500 times) | Every 10-14 days |
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.
Correct timing is important for maximizing the effectiveness of foliar iron fertilizer.
The ideal time to apply is when crops begin showing symptoms such as:
Interveinal chlorosis
Pale or yellow young leaves
Reduced leaf greenness
Weak shoot development
Reduced plant vigor
Early application is generally preferable to waiting until deficiency becomes severe.
Crops have increasing nutrient requirements during periods of rapid leaf and shoot development. Foliar iron application during active growth can provide timely micronutrient supplementation.
Application can be considered before periods when crops experience high nutritional demand, such as:
New leaf development
Rapid shoot growth
Flowering
Fruit development
Fruit enlargement
Iron availability can be affected by soil and environmental conditions. Foliar application can be particularly useful when the crop’s root system has difficulty obtaining sufficient available iron from the growing medium.
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.
4. Safety: Keep out of reach of children; Not for human or animal consumption; In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
Ferrous iron fertilizer is a micronutrient fertilizer that supplies iron in the ferrous form (Fe⊃2;⁺). It is used to supplement crop iron nutrition and help address symptoms associated with iron deficiency, such as interveinal chlorosis and leaf yellowing.
It is mainly used to provide supplemental iron to crops and support healthy leaf color, chlorophyll formation, photosynthetic activity, shoot development and overall plant vigor.
It can help provide supplemental iron when crops show iron deficiency symptoms. Foliar application delivers iron directly to plant foliage and can be useful when root-zone iron availability is limited.
Common symptoms include interveinal chlorosis, yellowing of young leaves, pale foliage, reduced plant vigor and weak new growth. Severe deficiency can affect overall crop development.
Yes. This product is specifically recommended for foliar application. Spraying the diluted fertilizer onto crop foliage provides a direct route for supplemental iron nutrition.
Yes. It can be used on fruit crops such as citrus, cherry, grape, apple and pear, as well as vegetables like tomato, pepper, cucumber, melon and leafy vegetables, especially when iron deficiency symptoms appear.
The best time is generally during active growth or when early iron deficiency symptoms appear. Morning or late afternoon is preferable to avoid excessive heat and strong sunlight.
Compatibility depends on the specific products being mixed. A jar test and small-scale crop test are recommended before tank mixing. Avoid mixing without checking compatibility, especially with strongly alkaline products or reactive formulations.
