Vector: Aphids

Viral Disease

A viral disease, first reported in 2015, significantly affects cumin crops, causing yield losses of up to 30%. The disease is transmitted by aphids and exhibits a range of symptoms that impact plant health and productivity.

1. Symptoms

• Mosaic patterns on leaves.
• Leaf distortion and enations (outgrowths).
• Yellowing of leaves and stunted growth.
• Bushy appearance of infected plants.
• Symptoms start on young leaves and spread to the entire plant.

2. Impact

• Yield losses reported up to 30%.
• Severe damage to plant vigor and seed quality.

3. Transmission

• Spread by aphids, which act as vectors for the virus.

4. Management Strategies

• Monitor and control aphid populations using insecticides or natural predators.
• Remove and destroy infected plants to reduce disease spread.
• Use virus-free seeds and resistant varieties, if available.
• Implement crop rotation to break the disease cycle.

5. Conclusion

Proactive measures, including vector control and disease monitoring, are essential to minimize the impact of this viral disease on cumin crops. Integrated pest and disease management is critical to safeguarding yields.
