Italy approves Bayer’s prothioconazole
Bayer CropScience has been granted approval for its systemic fungicide, prothioconazole in Italy. The company is to market two products based on the active ingredient. One is a single ai fungicide, Proline (prothioconazole 250 g/litre), and the other a combination product, Prosaro (prothioconazole 125 g/litre + tebuconazole 125 g/litre). They are emulsifiable concentrate formulations for use on wheat and barley against diseases, such as rust ( Puccinia spp), powdery mildew ( Blumeria graminis) and Fusarium spp. Prothioconazole received its first registration in Germany in 2004 as Proline ( Agrow No 453, p 21). Bayer then noted the development of resistance to strobilurin fungicides in leaf diseases was leaving growers with few alternative modes of action ( Agrow No 502, p 18).
