With soybean planting completed in some regions, seedlings are emerging in early planted soybean fields.

Phytophthora root and stem rot is a common disease in soybeans. It is caused by a fungal pathogen, Phytophthora sojae (P. sojae), which is prevalent in poorly drained soils with high clay content, Ohio and eastern Indiana are known for such soils.

Soybean seed size is determined partially by the variety (genetic tendency) but mostly by the growing conditions experienced at the production location. Several factors influence soybean seed size.

Winter annual weeds have been getting a little more attention in recent years. Many producers simply ignore them, because they are not an issue during the growing season. In addition to weed competition issues, winter weeds may be adding to other pest problems.

Most soybeans are still covered by a variety patent, and you will not be able to save and plant the seed from those varieties without a license giving you that added right. Check with your seed supplier before saving.

As corn and soybeans emerge, evaluating the stand is important to identify problems from planting, insects, or disease. Evaluating your stands early can help you identify concerns while there may be time to remedy them.
