Green Gram, one of the most important Pulse crops, globally faces threat from Pests and Diseases. This blog explains the main threat in the Green Gram crop called "Anthracnose", leading to significant yield losses if left unchecked. In this article, we'll explore effective measures to control and manage Anthracnose disease.
What is Anthracnose?
Green gram, also known as mung bean, is a vital legume crop cultivated worldwide for its nutritious seeds. Unfortunately, several fungal diseases can threaten its yield, with anthracnose being a major culprit. Caused by the fungus Colletotrichum lindemuthianum, this disease can significantly impact green gram production, causing yield losses ranging from 30% to 70% in severe cases.

Favorable factors of Anthracnose in Green Gram Crop
The fungus thrives in moderate temperatures, particularly between 22-28°C (72-82°F). Temperatures outside this range can hinder disease development, High relative humidity (above 85%) is crucial for anthracnose development and spore germination.
Symptoms of Green gram crop affected by Anthracnose
Main symptoms of plant affected by Anthracnose are:
- Leaves: Circular, black, sunken spots with dark centers and bright red-orange margins. In severe cases, leaves may wither and fall off.
- Stems and petioles: Dark brown, sunken, circular to elliptical lesions that may girdle the stem and hinder water transport.
- Pods: Small, reddish-brown, slightly sunken circular spots that rapidly enlarge into larger, dark-sunken lesions, distorting the pod and affecting seed development.
- Seeds: Infected seeds may appear discolored, shriveled, or have sunken lesions, impacting germination and quality.
