When we think about maximizing soybean performance, there are many agronomic factors to consider. Agronomists usually discuss variety selection, varietal maturity, seed treatment, seeding rate, planting depth, fertility, pest and weed control, and planting date, to name some of the key factors. In this article, I am going to focus on the importance of planting date and how it impacts soybean performance.

The soybean Podworm (SPW) (Helicoverpa zea) feeds on many different grain and vegetable crops in much of the United States. SPW has many different names depending on which crop it is feeding on. These names include cotton bollworm, tomato fruitworm, sorghum headworm, and most commonly corn earworm. Often SPW is a soybean pest of the southern US; however, depending on several factors, this species can become a problem in soybean fields further north and east, making its presence felt in areas where it isn’t usually an economic pest.

Charcoal rot is a fairly common disease in dry portions of the U.S. where soybeans are grown. Most years, it's easy to find charcoal rot in areas of Missouri and Kansas; however, the disease is typically challenging to find in geographies further to the east and north.

Agronomists get many calls during a typical growing season when things aren't going right in corn and soybean fi elds in the geographies that we cover. Most of the time, problems are caused by common diseases or insects. Sometimes, though, we receive calls about damage to plants that is caused by uncommon pests.
