Integrated Crop Management News

Publication Date



In the June 29 issue of the ICM newsletter, XB Yang discussed the effects of the wet 1998 growing season on fungal soybean diseases. Growers and agribusiness also should be aware of two issues concerning the soybean cyst nematode (SCN) and the wet weather that we have experienced so far this growing season. First, SCN is moved by anything that moves soil. Consequently, any field or area of a field that has flooded may have had the nematode introduced into the field. Random survey results from 1995-1996 indicate that approximately two-thirds of the corn-soybean fields in Iowa are infested with SCN.
