Brazil’s soy rust/whitefly controls cost $25 bn in decade
Brazilian growers have spent some $25 billion over a decade on pesticides to combat Asian soybean rust (Phakopsora pachyrhizi) and whiteflies (Trialeurodes vaporariorum), national media report. They cite a study from the Mato Grosso soybean growers association, the Aprosoja. Some 35 new pests and diseases have been identified in that period in Brazil, with the most costly, earworms (Helicoverpa spp), reportedly causing $2 billion in losses in the first year. The Aprosoja presented its study on the threat of imported pests at a Sao Paulo event at the end of June.
