Integrated Crop Management News

Our cooperators have worked hard to establish sentinel plots across Iowa. As of May 1, we have 25 of the 30 plots sown and five plots have begun to emerge. Cool temperatures have temporarily halted plant development. We are thankful that, to date, we have lost no plots to frost. Our objective with these plots is to have an early warning should soybean rust reach Iowa. Our strategy for detecting rust early is to have known areas where the host and environment will allow disease development and to closely monitor these areas.
