Evaluation of Integrated Disease Management Modules against Wilt Disease of Ajwain {Trachyspermum ammi Sprague) Caused by Fusarium solani

摘要

Integrated disease management modules against wilt disease of Ajwain were evaluated during Rati season 2015-16 and 2016-17 under pathogen inoculated condition. The module comprising in-furrow soil application of de-oiled neem cake mixture @ lOOg sqm "enriched with Pseudomonas + Trichoderma bio-formulations each @ 2 per cent at sowing + seed treatment with carbendazim 50 WP @ 0.1 per cent and drenching with tebuconazole 25 EC @ 0.10 per cent at 45,60 and 75 days after sowing resulted in minimum wilt disease (18.3%), maximum control (79.7%) with higher seed yield (9.7q ha~(-1)) and was found best effective compare to rest of the treatments and control. This was followed by module comprising in-furrow soil application of de-oiled neem cake mixture @ lOOg sqm 'enriched with Trichoderma bio-formulation @ 2 per cent at sowing + seed treatment with carbendazim 50 WP @ 0.10 per cent and drenching with tebuconazole 25 EC @ 0.10 per cent at 45,60 and 75 days after sowing resulted in 29.0 per cent wilt incidence, 67.9 per cent disease control and 8.3q ha~(-1) seed yield. Enumeration of rhizospheric population of T. viride, P. fluorescens and pathogen revealed reduced count of F. solani and increased count of T. viride and P. fluorescens played significant role in suppression of the wilt disease.
