Brazil to widen supply of soybean rust fungicides
The Brazilian Ministry of Agriculture intends to widen the supply of fungicide modes of action for the control of Asian soybean rust (Phakopsora pachyrhizi). It has recently approved the sale and use of BASF's carboxamide fungicide, fluxapyroxad (trade-marked as Xemium - see this issue), and there are another two unnamed active ingredients receiving "maximum priority" for analysis by the registration authorities. The fluxapyroxad approval was the first for a carboxamide ai in Brazil, and the Ministry wants further new ais. "The Ministry urgently requested approval of the substance in order to promote competitiveness and fair prices for growers," says co-ordinator general of the Ministry's pesticide office, Luis Rangel.
