What is Chickpea Anthracnose Disease?

Chickpea Anthracnose Disease is a fungal disease that affects chickpea plants. It is caused by the fungus Colletotrichum truncatum and can cause significant damage to the crop. The disease primarily affects the leaves, stems, and pods of the plant, leading to leaf spots, stem cankers, and pod rot.

Symptoms Cause Management
Brown to black lesions on leaves, stems, and pods Fungal pathogen Colletotrichum species Plant resistant varieties, crop rotation, proper sanitation
Lesions may have concentric rings or dark borders Spread through infected seeds, soil, and plant debris Regular scouting, early detection, and removal of infected plants
Premature defoliation and reduced yield Humid and warm weather conditions favor disease development Use of fungicides, promoting good airflow, and avoiding overhead irrigation

What are the Symptoms of Chickpea Anthracnose Disease?

The symptoms of Chickpea Anthracnose Disease vary depending on the stage of infection. In the early stages, small circular lesions with dark brown centers and reddish-brown margins may appear on the leaves. As the disease progresses, these lesions can enlarge and coalesce, causing defoliation. Infected stems may develop sunken lesions or cankers, leading to wilting and dieback. Infected pods may show dark brown spots or rot.

  • Wilting of the leaves
  • Dark brown to black lesions on the stems and pods
  • Yellowing and browning of the leaves

How is Chickpea Anthracnose Disease Diagnosed?

Chickpea Anthracnose Disease can be diagnosed through visual inspection of the plant symptoms. However, laboratory analysis may be required for accurate identification of the fungal pathogen. This can involve isolating and culturing the fungus from infected plant tissues and conducting microscopic examination and molecular tests.

  1. Visual Inspection: The first step in diagnosing chickpea anthracnose disease is to visually inspect the plants for symptoms. Look for dark, sunken lesions on the stems, leaves, and pods of the plant.
  2. Isolation of Pathogen: Once symptoms are observed, the next step is to isolate the pathogen responsible for the disease. This can be done by collecting a sample of the infected tissue and culturing it on a suitable medium.
  3. Microscopic Examination: After the pathogen has been isolated, a microscopic examination is conducted to identify the fungal spores or structures present. This helps confirm the presence of the anthracnose-causing fungus.
  4. Molecular Techniques: In some cases, molecular techniques such as PCR (Polymerase Chain Reaction) may be used to detect and identify the specific fungal species causing the anthracnose disease.
  5. Pathogenicity Tests: To confirm that the isolated pathogen is indeed the cause of chickpea anthracnose disease, pathogenicity tests are performed. These involve inoculating healthy plants with the isolated pathogen and observing if similar symptoms develop.

What are the Causes of Chickpea Anthracnose Disease?

The primary cause of Chickpea Anthracnose Disease is the fungus Colletotrichum truncatum. The disease spreads through infected seeds, crop debris, and contaminated soil. Favorable environmental conditions such as high humidity and rainfall can also contribute to the spread and severity of the disease.

Fungal Pathogens Environmental Factors Host Plant Susceptibility
Colletotrichum species High humidity and rainfall Chickpea cultivars with low resistance
Ascochyta rabiei Warm and wet conditions Lack of genetic resistance
Botrytis cinerea Prolonged leaf wetness Plant stress and weakened immune system

How to Manage Chickpea Anthracnose Disease?

Managing Chickpea Anthracnose Disease involves a combination of cultural, chemical, and genetic control methods. Crop rotation, removal of infected plant debris, and use of disease-resistant varieties can help reduce the incidence of the disease. Fungicides may be used as a preventive measure or to control severe infections. Proper irrigation practices and maintaining good field hygiene are also important for disease management.

To manage chickpea anthracnose disease, practice crop rotation, use disease-resistant varieties, maintain proper spacing, and apply fungicides when necessary.

What are the Best Practices for Chickpea Anthracnose Disease Prevention?

To prevent Chickpea Anthracnose Disease, it is recommended to use certified disease-free seeds and practice crop rotation with non-host crops. Avoiding overhead irrigation and promoting good air circulation in the field can help reduce humidity levels and minimize disease development. Regular scouting and early detection of symptoms can also aid in timely intervention and prevention of further spread.

Implementing crop rotation, using disease-resistant varieties, practicing good sanitation, and applying fungicides are important measures for chickpea anthracnose disease prevention.

Are there Resistant Varieties Available for Chickpea Anthracnose Disease?

Yes, there are chickpea varieties available that have been bred to be resistant or tolerant to Anthracnose Disease. These varieties have shown reduced susceptibility to the disease and can be a valuable tool in managing its impact. It is advisable to consult local agricultural extension services or seed suppliers for information on resistant varieties suitable for your region.

1. Genetic Resistance

Chickpea breeders have been working towards developing resistant varieties for anthracnose disease. Through traditional breeding techniques, they have identified genetic markers associated with resistance and incorporated them into new cultivars. These resistant varieties show reduced susceptibility to the disease and can help in managing anthracnose effectively.

2. Host Resistance Screening

Researchers have also been conducting screening programs to evaluate different chickpea germplasm for resistance against anthracnose. By subjecting various varieties and accessions to the pathogen, they can identify those with natural resistance. This information can then be used to develop new resistant varieties or to further enhance the resistance in existing ones.

3. Disease Management Strategies

In addition to genetic resistance, integrated disease management strategies are employed to control anthracnose in chickpea crops. This includes practices such as crop rotation, use of fungicides, and implementing cultural practices that reduce the spread of the pathogen. By combining these strategies with the use of resistant varieties, farmers can effectively manage and reduce the impact of anthracnose disease.
