Abstract:
Field experiments on varietal testing in sick soil for wilt of gladiolus was carried out during 2020-2021 at Dr. PDKV Akola. The result indicated that none of the variety of gladiolus was found immune to wilt disease out of 46 observed. 16 were resistant, 4 were moderately susceptible, 25 were moderately resistant, and 1 was susceptible under natural field condition. Fusarium solani was observed as the pathogen involved in causing wilt disease of gladiolus at Akola. Temperature of 25 ⁰C and pH of 6.5 was observed more suitable for the growth of F. solani compared to 15 and 35 ⁰C temperature and 5.5 and 7.5 pH. Among five root extracts tested Chrysanthemum root extract with 71.50%, 66.66%, and 67.70% growth inhibition of F. solani at 15 °C, 71.05%, 64.72%, and 63.89% at 25 °C and 69.77%, 63.89%, and 67.35% at 35°C respectively at 5.5, 6.5 and 7.5 pH was superior over all other followed by Tuberose, Marigold and fenugreek root extract.
