Evaluation of different fungicide, bioagent and phytoextract against Fusarium oxysporum f. sp. capsici. under in vitro condition

Abstract

Fusarium wilt of chilli caused by Fusarium oxysporum f. sp. capsici has been emerging as one of the biotic threats in profitable cultivation of chilli crop. The fungicides evaluated in vitro against Fusarium oxysporum f. sp. capsici were significantly reduced the mycelial growth. Among that Benomyl 50% WP and Copper oxychloride 50% WP were found most effective with maximum growth inhibition (100%) and (86.65%). Antagonist tested against Fusarium oxysporum f. sp. capsici in vitro significantly reduced the growth of test pathogen. Among that Trichoderma virens inhibitited (92.38%) and Trichoderma harzianum (89.33%) found to be most effective with highest mycelial growth. Among the botanicals tested against Fusarium oxysporum f. sp. capsici, the Allium sativum @ 10% and 20% were found most effective with significantly highest growth inhibition 43.61 and 53.86% respectivly, then Brassica juncea L. @ 10% and 20% with growth inhibition 32.90% and 42.19%.
