Effectiveness of Cultural and Biological Management Approaches For Karnal Bunt Disease of Wheat Caused By Neovossia Indica (Mitra) Mundkur

Abstract :

Karnal bunt incidence greatly depends upon weather and agronomical practice thus studies were conducted to ensure best environment in field for disease free crop. Studies indicated that early sowing is recommendable as it shifts the panicle stage from 2nd week of Feb (Most susceptible period). 25th of Nov (1.70%) was found most susceptible, however least disease incidence was observed with 5th December (0.78%) followed by 26th October (0.88%).Studies on irrigation schedule shows that judicious use of irrigation manages the spread of the disease. Irrigation at later stages (Flowering) was more prone to disease hence after fourth irrigation only life saving irrigation may be given. Plouging depths on disease incidence indicated that with the increase in depth of sowing, disease intensity was more. Fungal bio agents like Trichoderma viride and Trichoderma harzianum, significantly more effective than bacterial bio-agents treatments in karnal bunt disease of wheat management.
