Soybean rust up 65% in Brazil in 2012/13
The occurrence of Asian soybean rust ( Phakopsora pachyrhizi) made a comeback in Brazilian soybean plantings in 2012/13. Recorded incidences rose by almost two-thirds (65%) in the year to March 2013 compared with the previous 12 months to 435, according to the official soybean rust research association, the Consorcio antiferrugem. However, that remains well below the incidences of the immediately preceding years. The Consorcio recorded 706 incidences in 2010/11 and over 2,300 in 2009/10. Brazilian farmers spent $1,300 million on treating soybeans against rust in 2011, accounting for more than half (56%) of the fungicide market ( Agrow No 646, p 22).
