Tiny Terrors: The Soybean Aphid

Abstract

known how these other hosts may playa role in the over-wintering of the fungus, and if they will provide a broader geographic base than that currently known for kudzu. Because the introduction of soybean rust is relatively new to the continental United States, much remains unknown about the potential in-season and overwintering distribution of the fungus. It seems likely, as it is with most invasive species, that it may take a decade to fully understand the distribution of the fungus and its capacity to cause economic losses to the U.S.soybean crop.
