The crown rot disease was recorded for the first time on strawberry Field from Hill Millet Research Station, Waghai, Gujarat state of India during 2017-2018. The diseased plants showed drying from the edge of the leaves. Dark lesion appears first on leaves and spreads downward to the crown region. The severely infected plant parts i.e., leaves, flowers, stems, fruits and roots are gradually turned into dark black in colour and later on plant had completely dried and resemble the symptoms of crown rot. The fungus was isolated from the diseased plant parts and subsequent re-inoculation of the same to healthy plants and its pathogenicity confirmed which revealed that Pestalotiopsis clavispora (G.F. Atk.) Steyaert is the causal organism. Pathogenicity tests showed that Pestalotiopsis clavispora could infect strawberry, which developed the same symptoms under artificial inoculation conditions to that observed in the field. Further, the fungus was identified based on morphological and cultural characteristics and this is the first report from India showing that Pestalotiopsis clavispora causes crown rot on strawberry.
Colletotrichum gloeosporioides is known to have a wide host range and has become progressively more important pathogen on many economic crops worldwide. C. gloeosporioides was isolated for the first time from areca palm (Chrysalidocarpus lutescens H. Wendl.) in south Gujarat region. C. gloeosporioides was classified based on the morphological characteristics. To the best of our knowledge, this is the first report of C. gloeosporioides causing leaf spot of areca palm in India.
The incidence of rust (Uromyces sp.) on chickpea cv. GG-2 was first noticed during the rabi-2018 in south Gujarat, India. Symptoms were observed initially just after flowering stage on the lower leaves and consequently on upper leaves as small, round or oval, light brown to dark brown pustules, which coalesces later to form bigger pustules covering with a ring of small pustules under field conditions.The disease severity ranged from 24 to 30%. The urediospores were observed to be yellowish to brownish in colour. The shape of urediospores was observed as globose, echinulate, measuring 18-26 µm in diameter. Based on the symptomatology and morphological characters of the uredospores, the pathogen was identified as Uromyces sp. This is thought to be the first report of the pathogen causing chickpea rust from south Gujarat, India. Chickpea, rust, Uromyces sp.
