Agchem use to rise on Brazil soy rust
Brazilian rust-monitoring researchers expect a stronger outbreak of Asian soybean rust ( Phakopsora pachyrhizi) this season than in recent years, according to national media reports. Incidences are three times higher than last season, according to the Brazilian agricultural soybean research corporation, the Embrapa Soja. Lead researcher Claudia Godoy reportedly cites the influence of the phenomenon, El Niño, which periodically affects climate in South America. “The rains associated with El Niño produce ideal conditions for the spread of the disease, which should be more severe this season,” she told newspaper Gazeta de Povo. It cites a distributor expecting a rise to four fungicide applications this year from the typical two. The first appearance came earlier this year than last, but so did the first planting ( Agrow No 581, p 16).
