Fruit rot of mandarin orange
In December 1978, the author observed the stored fruits of Citrus reticulata Blanco severely infected by a fungus causing soft rot in local fruit market of Faizabad. The entire fruit surface was densely covered by the fungus causing the rot. The fungus was isolated on PDA medium and identified as Trichoderma lignorum (Tode) harz.
In India, T. lignorum has been found on various substrates, viz., soil, rhizosphere region of Pennisetum typhoides, paddy straw of mushroom beds, phyllosphere of Impatiens balsamina and Citrus crysocarpa but not on Citrus reticulata and the present association is a new record for India. (Link)

Notes on a new fungal disease of Alocasia indica
Short hole disease of Alocasia indica Schott, caused by Phoma exigua Desm., earlier unknown to India has been reported from Faizabad. The infection was chiefly confined to the margins of lamina. It started as small nonchlorophyllous spots near the fronds. The spots gradually enlarged irregularly upto 2-3 cm sq. area of the leaf, merged and in final stage, necrosis and then short holes appeared within a month. The pathogenicity tests performed by standard methods proved pathogenic nature of the fungus.(link)Cited this as : R.S. Kanaujia (1978): Notes on a new fungal disease of Alocasia indica.

Wet rot of Amaranthus viridis
During survey of fungi causing disease in plants at Faizabad (U.P.), authors observed infection of wet rot disease on Amaranthus viridis L. plants growing as mixed crop with Abelmoschus esculentus at Ram Kote, Ayodhya of Faizabad district in September, 1976. The infection was severe during flowering when percentage of infection recorded was upto 60-70. The microscopic studies of the original specimen and that grown on Czapek's Agar Medium match with the description of Gilman for Choanephora cucurbitarum (Berk. & Rav.) Thaxter. The pathogenicity of the fungus was established. This is the first report of this fungus on Amaranthus viridis (Chaulai). (Link)
