Year: 2020
Type: article
Abstract: Phomopsis vexans affected stem and fruit of brinjal crop collected from the field and isolated on potato dextrose agar (PDA) produced white cottony growth, sub-aerial mycelial, circular shaped colony with indistinct zonation and good sporulation. Pigmentation is yellow to dark brown colour. Pycnidia formation takes place after 18 to 20 days which are dark brown in colour and scattered distribution on the media surface. Morphological characteristics of Phomopsis vexans revealed hyaline, septate mycelium which measures 2.9 to 3.7 μm in diameter. The alpha conidia which were one celled, hyaline and subcylindrical to elliptical were measuring 8.1 μm (length) x 2.2 μm (width) on stem and 7.5 μm (length) x 3.5 μm (width) on fruit. Pycnidia produced on host surface (87.2-283.0 μ x 90-303 μ) and on cultural medium (58.49-381.49 μ x 79.3- 439 μ).
