effects of three biological products on rice sheath blight disease in the field

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Rice Sheath Blight Disease Resistance Identified in Oryza spp. Accessions

Bioefficacy of Strobilurin Based Fungicides against Rice Sheath Blight Disease

As the usage of fungicides catapulted with the onward march of the dial hour, fungicidal resistance by the pathogens emerged as a new constraint. This amalgamated with the growing demand by the farmers for crop protection agents with low use rates, a benign environmental profile and a low toxicity to human and wild life, further gave an impetus to the search of new molecule of fungicides with n...

Sheath Blight and Its Management in Rice

Rhizoctonia solani AG1-IA, is the most economically important disease in Texas and other southern rice-producing states. The disease is widespread and occurs every year. The disease was first reported in Japan in 1910, and was soon well established in many Asian countries (Lee and Rush, 1983). The pathogen is capable of infecting rice, soybeans, grass weeds, and hundreds of other plant species ...

optimization of inoculation method in sheath blight disease to detect rice cultivars actual reactions in the field

sheath blight disease, caused by rhizoctonia solani ag-1 ia, is one of the most serious fungal diseases of rice, worldwide. rice resistance is a relative phenomenon and disease response varied (due to complex quantitative inheritance and high environmental diversity), so an accurate disease assessment would be difficult. to detect a reliable reaction of rice in a high level of disease developme...

Effects of Elevated Atmospheric CO(2) Concentration on the Infection of Rice Blast and Sheath Blight.

ABSTRACT The effect of elevated atmospheric CO(2) concentration on rice blast and sheath blight disease severity was studied in the field in northern Japan for 3 years. With free-air CO(2) enrichment (FACE), rice plants were grown in ambient and elevated ( approximately 200 to 280 mumol mol(-1) above ambient) CO(2) concentrations, and were artificially inoculated with consist of Magnaporthe ory...
