Bayer CropScience has been granted regulatory approval for its active ingredient isotianil in Japan. The new rice fungicide – marketed by Bayer CropScience under the brand name Routine® – was successfully launched in Korea in 2010. The market launch in Japan is scheduled for 2011, with further major rice-growing countries in Asia to follow as a measure to strengthen the company's portfolio in this region.
Isotianil was jointly developed with the Japanese company Sumitomo Chemical Co., Ltd. specifically for use in rice-growing in Japan to combat the plant disease rice blast. It originates from the chemical class of isothiazoles and stimulates the natural defense mechanisms of rice plants, thus boosting their resistance. This is the first time that it has been possible to find a substance that combines low application rates with what is termed a resistance-inducing effect.
