Iron deficiency in legumes

Name of the disease

Iron deficiency in legumes

The scientific name

Fe deficiency

Type of disease Family of disease

Type: Bio

Disease family: physiological diseases

Symptoms of iron deficiency

Symptoms of its deficiency are characterized by the appearance of a yellow color between the veins in new leaves. As the deficiency continues, the color of the tissue between the veins turns to ivory white, and the veins remain green. In cases of severe deficiency, very young leaves may become entirely yellow.

Causes of iron deficiency

Soil PH is one of the most important reasons that lead to the appearance of symptoms of iron deficiency on plants. Soils in which the PH is high (alkaline) work to convert the dissolved iron in the soil solution into bound iron that is not usable by the plant, as in calcareous soils.

Fertilizing with large amounts of soluble phosphate leads to the transformation of soluble iron into an insoluble form due to the combination of iron phosphate with the phosphate ion, forming iron. This phenomenon is greater in sandy lands than in clay lands, because sandy lands are less able to stabilize phosphate than clay lands. .

Conditions suitable for the spread of the disease

Its pH is higher than 7 PH, the soil is rich in phosphorus

Disease development cycle

Photos of the disease at its beginning and after its spread, in high quality, at least 5 photos in high quality

Losses of disease spread

Iron is considered an essential element for the formation of the chlorophyll molecule responsible for the green color in plants. Although it is not included in its composition, this is because iron is included in the synthesis of the enzymes responsible for the formation of chlorophyll.

Control strategy
Chemical fertilizer
Organic fertilizer
Preventive measures to prevent the occurrence of the disease

When symptoms of iron deficiency appear on plants, plants must be treated by adding chelated iron in the form of EDDHA, which is added watering water and chelated iron in the form of EDTA, which is used as a spray on the foliage.
