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...

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

abstract sheath blight is an important rice disease in the mazandaran province of iran. biological control of this disease as alternative of chemical control with propiconazol (tilt) fungicide, examined with 3 biological products, trichodermin ab, trichodermin b and subtilin produced in iran. at first in the laboratory, fungi and bacterium isolated and purified from these products, and their ab...

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...
