What Is Wrong With My Fenugreek?

Are there any angular or circular green to gray spots with brown borders on leaves?

Are the leaves covered with white powder?

Are there discoloration of the vine at the soil line, cankers appear on the stem and may spread upwards, numerous small black sclerotia develop in affected tissues?

Do the leaves have pale areas on upper surfaces and "downy" patches underneath?

Are the leaves curled and yellow?

These symptoms indicate a fungal disease - Cercospora leaf spot. This fungal disease only occurs in very warm climates. Spots develop a “frog-eye” appearance with light centers and dark edges. Spray plants with copper as soon as symptoms appear to prevent further symptom development.

White, powdery patches on the leaves are caused by a fungal disease Powdery mildew. Powdery mildew usually appears in damp places. Encourage good air circulation around the affected plants by thining them and any surrounding plants. Water plants from bellow to keep foliage dry. Any affected leaves should be cut off and removed. The appropriate fungicidal spray will protect your plant from further infections.

Charcoal rot is a fungal disease that attacks fenugreek. The fungus had a wide host range and affects beans, tobacco, soybean, pigeon pea, and many other crops. Organic soil amendments such as the addition of manure or neem cake can be used to reduce levels of inoculum in the soil.

Pale areas on upper surfaces of the leaves and "downy" patches underneath are caused by Downy mildew. This fungus spreads quickly during cool, wet nights and warm, humid days. Leaves will wilt and die. Remove and destroy all affected plant parts and encourage good air circulation around plants by thining them. Water plants early in the morning to make sure they dry before nightfall.

Distorted, curled leaves are caused by aphids. These tiny insects cluster under leaves and on growing tips where they feed on plant sap. You can control them by washing them off the plant with water spray. Insecticidal soap should be used with severe infestations.

If there are tiny holes in leaves they are caused by Flea beetles. These tiny, black, brown, or bronze beetles hop when disturbed. Larvae are small and white, feed mostly on the undersides of leaves. Prevent problems by covering young plants with row cover. Control severe infestations by spraying or dusting plants with pyrethrin.
