Combatting Aphid Infestation, Root Rot, and Rust Disease in Lentil Cultivation

Introduction:
Lentil (Lens culinaris Medik.) is a major pulse crop in Bangladesh, contributing significantly to dietary protein intake. However, the productivity of lentil is often threatened by biotic stressors, including aphid infestation, root rot, and rust disease. This blog explores recent research findings on these challenges and their impact on seed yield. Visit https://www.plantsciencejournal.org/jpsp for more groundbreaking research in plant science.

The Impact of Aphid Infestation on Lentil Yield
Aphids (Aphis craccivora) are a persistent pest in lentil fields, feeding on plant sap and acting as vectors for viral diseases. Research conducted in Bangladesh showed that aphid populations peaked between the 7th and 9th standard meteorological weeks (SMW), with BARI Masur-6 exhibiting the lowest infestation levels. Environmental factors such as temperature, humidity, and rainfall were positively correlated with aphid proliferation, directly impacting yield reduction.

Root Rot Disease: A Silent Yield Killer
Root rot, primarily caused by Rhizoctonia solani and Fusarium oxysporum, leads to significant crop losses, particularly during the seedling stage. The study revealed that Binamasur-8 and Binamasur-9 experienced the highest disease incidence rates, whereas BARI Masur-6 and Binamasur-5 demonstrated greater resilience. This soil-borne disease often results in plant wilting, root decay, and overall yield reduction.

Rust Disease: A Major Foliar Threat
Rust, caused by Uromyces viciae-fabae, is another severe disease affecting lentil crops, leading to leaf drop and reduced photosynthesis. The highest disease severity index (DSI) was observed in BARI Masur-5 (74%), while BARI Masur-6 and BARI Masur-8 had the lowest DSI values. Preventive measures, such as selecting resistant varieties and adopting proper crop rotation, can mitigate rust outbreaks.

Key Findings and Best Practices for Farmers

• Aphid Management: Implementing timely monitoring and using eco-friendly pest control measures can minimize aphid impact.
• Disease-Resistant Varieties: Binamasur-10 demonstrated the highest seed yield (8.25 g/plant) despite environmental and pest stress, making it a promising variety for future cultivation.
• Weather Influence: Understanding the role of climatic factors can help in better pest and disease prediction, ensuring improved crop management strategies.
