Bayer launches Opalo in Spain

Bayer CropScience launched the herbicide, Opalo (aclonifen 400 g/litre + oxadiargyl 120 g/litre) earlier this year in Spain. It is for use on tomatoes, tobacco, onions, garlic and artichokes against a broad spectrum of weeds. The product is a new mix of active ingredients, giving complementary modes of action, Bayer says. Aclonifen completed the EU review process in 2008, and was to be added to the list of approved active ingredients in Annex I the EU agrochemical registration Directive (91/414) this year ( Agrow No 559, p 9). Oxadiargyl and ethiprole were originally developed by the Bayer forerunner, Aventis CropScience. Aventis first launched oxadiargyl in Japan for use on turf in 2002, as Fenax ( Agrow No 398, p 26).
