Sheath Rot

Abstract A description is provided for Sarocladium oryzae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Oryza sativa (rice). DISEASE: Sheath rot. This occurs in the upper leaf sheath enclosing young panicles and starts as oblong or irregular lesions with brownish margins and greyish centres, 0.5-1.5 cm long, which later enlarge and coalesce. Whitish mycelium may be seen in the centre of the lesions and occasionally inside the rotted sheaths. Severely affected panicles do not emerge, the effect being known as choking. The symptoms are evidently indistinguishable from those associated with S. attenuatum. GEOGRAPHICAL DISTRIBUTION: India, Bangladesh, Brunei, Kenya, Nigeria. Although it is not always possible when 'Acrocydndrium oryzae' is reported in the earlier literature to know whether S. oryzae or S. attenuatum is intended, the distribution of the former extends into S.E. Asia and the latter into N. America. TRANSMISSION: By conidial dispersal. Fungal attack is often associated with damage by pests - the boring beetle, Corticarina gibbosa (Amin et al.) or the mite Steneotarsonemus madecassus (Hsieh et al., 1977 with 'Acrocylindrium oryzae') and S. spinki (Chien & Huang, 1979).

Sheath Rot

Seeds of three aromatic rice (Oryza sativa L.) var. Kalijira, Kataribhog and BR 34 Jira dhan were tested by Blotter method for identifying their seed borne fungi. Fungi associated with seeds were Aspergillus niger, Apergillus sp., Carvularia sp., Cladosporium sp., Colletotrichum sp., Fusarium sp., Pyrenochaeta oryzae and Sarocladium oryzae. Infected samples were collected from the field starting from maximum tillering stage to grain filling stage of plant growth. After maximum tillering stage three fungal diseases were recorded on the stems and sheaths. Sheath rot was recorded on all the three rice varieties, stem rot was recorded on Kalijira and sheath blotch was recorded on Kataribhog. The pathogens of sheath rot, Sarocladium oryzae, sheath blotch, Pyrenochaeta oryzae and stem rot, Sclerotium oryzae were frequently associated with the respective samples. This is the first report of disease on aromatic rice plant for Bangladesh.

Sheath Rot

Abstract A description is provided for Sarocladium attenuatum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Oryza sativa (rice). DISEASE: Sheath rot. The symptoms are similar to those of sheath rot associated with S. oryzae. GEOGRAPHICAL DISTRIBUTION: India, Sri Lanka, Nigeria, Gambia, Mexico, USA. The distributions of S. attenuatum and S. oryzae overlap and many records of S. attenuatum must have been included in that of 'Acrocylindrium oryzae' before a distinction between the two species had been drawn, but S. attenuatum alone has been recorded for America and S. oryzae only in S.E. Asia. TRANSMISSION: Sarcocladium attenuatum has been isolated from Nilaparvata lugers, the brown plant hopper of rice (CMI records), which might suggest a similar role to that suggested for other rice pests and S. oryzae. Seedborne (56, 5628).
