Brazil cuts soybean fungicide use

Brazilian soybean farmers saved hundreds of millions of reals last year in fungicide purchases through the 90-day isolation period policy for soybean planting. The Mato Grosso soybean and maize farmer association, the Aprosoja, says that the implementation of the policy has been a major cause of a reduction in fungicide applications for use against Asian soybean rust ( Phakopsora pachyrhizi). Farmers spent R$400 million ($205 million at the current rate) less on fungicides in the 2008/09 season than in the previous year. The policy forbids the planting of seed for 90 days following harvests. It was pioneered in the state of Mato Grosso in 2006 and has since widened to several Brazilian states ( Agrow No 538, p 21).
