First report of crown rot disease of guava caused by Fusarium verticilloides in India

摘要

A survey was carried out in guava orchards during 2015 in Jabalpur district of Madhya Pradesh. Fruits of Thai guava were observed exhibiting initially, water-soaked lesions around the calyx region, which later enlarged into necrotic grayish-black circular patches that covered the entire fruits. The pathogen was identified as Fusarium verticilloides, which was confirmed by Indian Type Culture Collection, Division of Plant Pathology, ICAR-IARI, New Delhi (ID No. 9949.15). Fusarium verticilloides has been previously reported non-pathogenic for inducing crown rot on guava in Phillipines. This is the first report of F. verticilloides causing crown rot in guava in India.
