Early Season Crop Scouting
As crops start to emerge, now is a good time to get out and do early-season scouting to see how things went with planting and to also check for any early season crop disease and insect issues.

You know what they say: March comes in like a lion and out like a lamb.
Well, it certainly feels like this past winter was just one extended lion. While there were signs that maybe Iowa would be seeing greener pastures, that has not been the case, especially for farmers who have experienced flooding this past month. With the recent incidents and resulting disaster proclamations, as well as lost grain storage, the idea of farming greener pastures has a long way until fruition.
It is hot here in Iowa...but not hot enough to discourage us from hand planting a soybean trial evaluating novel germplasm for resistance to Phytophthora root and stem rot (PRR) caused by P. sojae. PRR causes stand and yield losses every year throughout the U.S.
Seedling diseases could be an obstacle for farmers this year with the early planting of corn and soybean. While we all hope that seedling diseases will be a small consideration, it is important to be ready for them. It is also important to know how to sample for them.
The percentage of soybean treated with a seed treatment has increased greatly in recent years. Over the past five growing season, the Robertson lab has evaluated the effect of commercial seed treatments on stand count, disease incidence and severity, and yield of soybean with funding provided by Iowa Soybean Association.
A new publication, webinars and survey results are available to those wanting to learn more about soybean seedling disease.

With soybean planting completed in some regions, seedlings are emerging in early planted soybean fields. Starting now and continuing for the next two weeks, producers should scout for soybean seedling diseases.
