Study Trip to Brazil Increases Understanding/credibility Concerning Asian Soybean Rust

Paul Kassel, FS/crops, Northwest Iowa


Asian soybean rust (ASR) was first discovered in the U.S. on November 10, 2004. Farmers and agribusinesses were concerned about potential damage from this disease in Iowa. Extension field specialist/crops were knowledgeable about ASR, but had not observed ASR first hand.


Iowa State University (ISU) Extension organized an educational trip for the field specialists/crops to travel to Brazil on February 10-20, 2005. The stops on the trip included farms, Ag chem/fertilizer dealers, an Embrapa research farm, and industry research plots. The ISU Extension field specialists/crops observed ASR in fields in southern Brazil (Parana) and northern Brazil (Mato Grosso).


The trip to Brazil provided an excellent source of background information on ASR. The field specialist/crops learned first hand the identification, impact and management of ASR. We also gained valuable contacts from other U.S. research and extension personnel. Paul Kassel included first hand information on ASR from the Brazil trip at the following meetings:

Extension clients gained some very important perspective on the scope and the impact of Asian soybean rust, a perspective on Brazilian agriculture, and now a better understanding of the use of fungicides for the management of Asian soybean rust. Extension Private Pesticide applicator Continuing Instructional Course (CIC) evaluations confirmed this. Ninety-five percent of the CIC respondents strongly agreed or agreed that the “information presented today was useful for my farm operation” and 98% strongly agreed or agreed that “the presenters were prepared and knowledgeable.” Page last updated:
