Bayer’s isotianil approved in Japan
Bayer CropScience has received approval in Japan for its rice fungicide, isotianil. The active ingredient was co-developed with Sumitomo Chemical specifically for use in Japan to tackle rice blast ( Pyricularia oryzae). It belongs to the isothiazole chemical class and stimulates the natural defence mechanisms of rice plants. This is the first instance of an ai that combines low application rates with a resistance-inducing effect, Bayer says. Very few crop protection products are currently approved for the control of rice blast, which is the world’s most economically damaging rice disease, it maintains.
