Kansas State

The wheat crop is fast approaching growth stages where fungicide should be applied. Many growers are asking about the potential need for fungicides this year. We have been conducting fungicides evaluations for the past three years in multiple locations in Kansas. Our goals are to (1) help growers evaluate which varieties are most likely to give a favorable yield response to fungicides, and (2) identify situations when these products are most likely to result in a yield response great enough to justify the applications.

During 2009 and 2010, we conducted tests at seven locations in Kansas with seed coating treatments and foliar iron treatments to correct iron deficiency symptoms in soybean. We used two varieties, one with good iron chlorosis tolerance and one that was susceptible to iron chlorosis. The tests were under irrigated conditions.
