Rice Sheath Blight Control with Flutolanil

Abstract

Flutolanil (α,α,α-trifluoro-3'‘-isopropoxy-o-toluanilide, Moncut®) is a new fungicide primarily developed for control of rice sheath blight caused by Rhizoctonia solani. In green-house studies, it was remarkably effective against sheath blight by both protective and curative foliar spray at more than 25 fig I ml with highly residual effects. The disease was effectively controlled by 80% at a concentration of 1.6-3.2&μlg. In addition, it exhibited acropetal movement in rice plants by both foliar spray and application to paddy water. In field studies, its foliar spray and dusting provided effective, long-term control over sheath blight&. © 1987, Pesticide Science Society of Japan. All rights reserved.
