Fungus Disease in Legume Plants


Legumes are a hearty fruit, which includes alfalfa, clover, beans, lentils, lentils and even peanuts. Forage, grains, lupins and timber species are all popular in the backyard garden for their nutritional value and easy growth management. Legumes, like any other plant, are susceptible to a variety of fungal diseases that can occur in a garden.

Fungal diseases

Fungal diseases spread through spores that are released from a mature fungus, and carried through the air on currents. Spores let out long tendril that spread throughout the dirt of your garden, attacking plants at the root and the lower portion of the legume stem. Often, fungal diseases are identified by their symptoms.

Vascular wilt

Vascular wilt is one of the more serious fungal diseases. When the vascular systems of the legume, the water carrying tissues of the plant, are infected by fungus, the plants ability to absorb water and nutrients are severally hampered. This causes the plant to appear dry and the shoots to fall off. Eventually the plant will die. Many legumes have a resistance, but the infection of a legume in the vascular system is most often deadly.

Rots and Leaf Blight

Many fungi will attack the roots, the crown or the stem of the legume causing a stunting in growth, a yellowing of fruit and leaves and may cause death of the plant. Leaf blight is caused by fungi pathogens, and usually attacks during wet weather when the air is humid and warm. Prevention of leaf blight can be aided by harvesting the plant on time, not giving the time for fruit to become rotted, which is an attraction to fungi pathogens.


Choosing well drained soil that is free from disease is the best preventative technique. If a plant has been infected, it is best to remove it from the area so that it does not spread spores or fungi to other plants. If grown in a container, the container should be washed out and new soil should be added before adding a new plant. Cleaning dead material from your garden such as leaves and rotted fruit and vegetables takes away the fungus' main source of food.


If the fungus is prevalent throughout the garden a fungicide can be used to kill or control the spores of a spreading fungi system underground. Fungicide can be applied by a spraying wand or through injection into the soil using a fungicide spear, which can be bought from garden centers. Apply fungicide at the beginning of the growing season before legumes are planted.
