This year's hurricane season started early and the arrival of Tropical Storm Arlene has raised some concerns regarding the risk of soybean rust (SBR) this season. The early start of the hurricane season reflects some similarities between the soybean rust situation and the southern corn leaf blight epidemic in 1970. In that epidemic, one major condition was an unusual tropical storm that occurred in June, which facilitated the spread of the southern corn leaf blight (SCL) pathogen from southern Mississippi and Alabama to the northern Corn Belt.
