Sheath rot disease of rice
-
A survey was conducted on Swarna cultivar (MTU 7029) of rice during Kharif 2013, 2014, 2015 and 2016 at Nadia district of West Bengal to record the fungal disease and their respective yield loss. Ten diseases (Leaf blast, Sheath blight, Sheath rot, Brown spot, Brown Leaf Spots caused by Curvularia lunata, Stackburn disease, Leaf spot caused by Nigrospora oryzae, Stem rot, Rotting by Choanephora cucurbitarum and False smut) were based on visual observation on Swarna rice cultivar and yield loss due to respective disease was calculated by measuring test weight (gm) of rice grains.

Six promising entries along with two checks showing resistant and moderately resistant reaction to sheath rot of rice at field during screening of advanced genetic material were analysed for biochemical constituent’s changes at pre and post inoculation stage (7 days after inoculation of S. oryzae) under pot condition during kharif 2019.

Among the fungal diseases in rice plants, brown spot disease caused by (Bipolaris oryzae) and sheath rot disease caused by (Sarocladium oryzae) are considered as serious threats in rice cultivation in India. Rice plant samples showing the brown spot and sheath rot disease were collected from different places.

Rice, Results obtained in the experiments conducted to find out effect of seed bio-priming on management of sheath blight and sheath rot diseases of rice in field condition revealed that seed bio-primed with Trichoderma harzianum applied at imbibition was proved to be an excellent bio-agent to manage sheath blight (Rhizoctonia solani) with minimum disease incidence (25.67%) and severity (21.63%) whereas Pseudomonas fluorescens applied at imbibition significantly manage sheath rot (Sarocladium oryzae) with minimum disease incidence (28.67%) and severity (23.41%).

Prior to the introduction of the modern varieties, the rice crop survived for centuries with traditional varieties with robust plant type but low yield. The farmers started applying higher doses of fertilizers in general and nitrogen in particular as these varieties were fertilizer responsive and these changes in rice cultivation resulted in an altered microclimate, which led to the accentuation of the insect pest and disease problems. Many diseases such as sheath blight, sheath rot, false smut and leaf scald have become severe in several parts of the country.

Rice is one of the major grains of the India and also significant part of national economy. Its production is severely affected by various biotic and abiotic stresses. Among different fungal disease stem rot of rice caused by Scleoritina oryzae leads to great losses. Under adverse conditions sclerotia are formed and act as main source of primary inoculum till the other collateral or/and alternate hosts appearance in the vicinity. Thus the present study is to know the best conditions that favour the sclerotial infection after the perpetuation.

Sheath rot disease caused by S. oryzae has emerged as one of the major diseases of rice inflicting yield losses ranging from 9.6 to 85% depending on the weather conditions. Pesticides are mostly used for its management and application of these chemicals over a long period may result in development of resistance, pesticide residue risk, health and environmental issues which necessitates an alternative economically feasible eco-friendly method for its management.

Sheath rot disease of rice is an emerging disease of rice inflicting severe yield losses. Chemical pesticides are exclusively used for the management of the disease and application of these chemicals over a long period may result in development of resistance, concerns about pesticide residue risk, health and environmental pollution and health hazards which demands for a sustainable means of disease management. The present investigation was carried out to evaluate the efficacy of few microbial antagonist viz. Trichoderma harzianum, T. asperellum, T. viride, T. pseudokoningii, T.
