Iron deficiency chlorosis (yellow leaf disease) in plants is a condition where plant leaves appear light green or yellow-green due to reduced chlorophyll content. The early symptoms appear on the young leaves of branches and then progress to older leaves. In the initial stage, the leaf veins remain green while the interveinal tissues turn yellow. In severe cases of iron deficiency, the edges or tips of older leaves on the middle and lower parts of branches may become scorched or necrotic and drop early.

Iron deficiency chlorosis (yellow leaf disease) in plants has become a persistent issue in alkaline soils and is a worldwide physiological disorder caused by nutrient deficiency. Iron deficiency in plants can lead to yellowing and wilting of leaves, inability to perform photosynthesis, branch dieback, reduced yield, and decreased quality. In severe cases, it can cause the entire tree or plant to dry up and die.

Product Features and Functions

1、This product is an EDDHA 0-0 isomeric molecule with high plant utilization efficiency. It is one of the better chelated iron compounds and is currently one of the most effective compounds worldwide for treating iron deficiency chlorosis in plants.

2、This product has strong biological activity and is suitable for soil pH values ranging from 3 to 10.

3、This product features good water solubility, fast dissolution, and high absorption and utilization efficiency by crops.

4、This product can be used for seed dressing, seed soaking, drip irrigation, hole application, and foliar spraying. It is an indispensable nutrient element in modern agriculture, floriculture, horticulture, and soilless cultivation industries.

Usage Methods and Dosage

1、Root Application: Dilute the product with water 2000-3000 times and apply around the drip line on both sides of the tree canopy or dig a 15-20 cm trench around it. Pour the solution evenly into the trench and cover immediately. Alternatively, drill holes around the drip line for application, with a depth of 15-20 cm, or dilute 2000-3000 times with water for drip irrigation.

2、Foliar Spray: Dilute with water 3000-3500 times and apply through foliar spraying.

3、The frequency and dosage of application can be adjusted according to the severity of iron deficiency in plants.

Precautions

1．Spraying should be done before 9:00 AM and after 5:00 PM to avoid high temperatures and strong sunlight.

2．EDDHA chelated iron has good solubility and is highly prone to moisture absorption and caking in the air, but this does not affect its efficacy.

3．The appearance color of EDDHA chelated iron may vary due to differences in pH, fineness, and air humidity, but this does not affect the intrinsic quality of the product.

4．This product should be kept out of reach of children and is not for consumption. In case of accidental ingestion, seek medical attention promptly.

5. This product should be stored in a cool, dry place and should not be exposed to strong sunlight. It should be stored away from light.
