Rust up by three quarters on Brazilian soy
A further study confirms and has magnified concerns of rising incidences of Asian soybean rust ( Phakopsora pachyrhizi) in Brazil in the last planting season. Appearances of the disease rose by almost three quarters (73%) in 2012/13, the official soybean rust research association, the Consorcio Antiferrugem, says. It recorded 461 appearances. The association warned of a 65% increase in March. However, the spread remains well below the peak of over 2,000 incidences in 2009/10. Rust has accounted for most of the fungicide market for the past few years ( Agrow passim).
