While August starts the downhill slope of the growing season, a lot is still happening out in the fields. Kernels and pods are filling out and we watch the sky for those ever-important August rains. We may often feel that there is little that we can do to impact the crop at this point in the season. However, there is much we can learn now by walking fields and asking ourselves which fields look the best and the worst.

August is the time we should continue to scout for late-season diseases and pests. Southern rust is the biggest issue we see in corn this time of year and is something you should definitely keep in the back of your mind.
Corn fungicide applications are always a highly debated topic. Many swear by them while others swear at them when they spend the money and see little or no yield benefit. Here are a couple things I like to consider before making an application...
August is a pivotal month for both corn and soybean yield development. The developing plants will need plenty of moisture, moderate temperatures, and adequate nutrient translocation to maximize the number, size, and weight of developing kernels/seeds.
What a year it has been. Many areas have experienced both hot and cold temperatures, as well as wet and dry spells. As we evaluate the crop in August, we have a great opportunity to take a hard look at yield potential and yield loss suffered this year.
Disease levels have been low in both corn and soybeans compared to this time last year. In corn, early observations near tasseling showed very light amounts of gray leaf spot, northern corn leaf blight, and common rust. Septoria brown spot has been observed in soybeans.
The 2016 crop continues to progress toward maturity with above average growing degree days and is pointing to an early corn harvest. Since last month’s issue, high temperatures during the weeks surrounding pollination alternated from well below to well above normal. The varying temperature periods served to prevent both northern corn leaf blight (NCLB) and gray leaf spot (GLS) from enjoying favorable conditions for extended periods.
Greetings, I am Jon Skinner, your new field agronomist for northern Illinois and Wisconsin. Born and raised on a row crop farm in central Illinois, I was ingrained with a passion and fascination for agriculture. This lead me to northern Illinois nearly nine years ago.
As August rolls around, we can start to see the finish line on the 2016 crop season. It started wet in many areas of southern Illinois, and then it turned hot and dry. Many areas received a much needed cool period and rain event around July 4th, which helped with the pollination of early planted corn.
August is an excellent time to develop cover crop establishment plans. Using cover crops to reduce soil erosion, improve soil organic matter and health, and sequester plant nutrients for future crops is gaining popularity in Missouri. As with the development of any new practice, the use of cover crops and their establishment can be challenging as one learns what works and doesn’t work on his or her farm.
From too much moisture, to not enough rain in the month of June, and weeks of intense heat, followed by cooler temperatures over the 4th of July, we’ve seen it all in eastern Iowa this year. While we are nearing the finish line, stay sharp and continue scouting.
One disease you may come across this season is Sudden Death Syndrome (SDS) in soybeans. SDS was first discovered in Arkansas in 1971 and occurs when the plant is infected by the fungal pathogen
By late August, corn is close to completing its lifecycle and is approaching physiological maturity (black layer). During this period there is not much we can do to impact yields, but it is still important to monitor crop
progress. Not only is it important to watch grain moisture after we reach black layer, it is also critical to monitor for development of stalk rot before and after black layer
This is an exciting time of year as many of our kids head back to school and those of us walking fields anticipate solid corn and soybean yields following a year of adequate rainfall and soil moisture.
At times rainfall was excessive, dew periods were long, and there were “perfectly timed” drops in air and soil temperatures at critical the stages of crop development that caused a “not so exciting” thing to look at in our soybean fields.

Most parts of Iowa experienced conditions that were drier and warmer than usual throughout the month of June. Recently though, we received some much needed rain. Unfortunately, in some instances, these rains were accompanied by high winds and thunderstorms which occurred just prior to corn tasseling in many fields. High winds just prior to tassel can cause green snap (brittle snap) in corn.

I have received a number of calls from customers over the past few weeks, so I wanted to provide some updates on a few of the hot topics as we continue to monitor the development of our corn and soybean crops.

The stressful growing conditions we experienced over the last month are in the rear view and we are wrapping up what has been an ideal period of weather during pollination. But many are wondering how does drought and extreme heat (similar to what we’ve experienced) affect corn during its vegetative growth stages? For the sake of being objective, let’s take a look at a reliable resource to determine how critical the hot, dry conditions were to your area.

A few corn fields may show yellowing or slight striping, but all in all corn is off to a solid start. Yellowing, striping or flashing can often be attributed to either rapid growth syndrome or the transition from seminal to nodal roots. The nodal roots provide the majority of the nutrient needs from the V6 growth stage on.
July is a critical month for corn and soybeans as both are going through critical reproductive growth stages. It is also a very important time to scout fields for diseases and insects. In 2015, Northern Corn Leaf Blight was very common in many areas, along with Gray Leaf Spot in others
July is a great month for crop growth. Corn and soybeans are beginning to move into those vital reproductive stages and seed development. Both are rapidly absorbing light for photosynthesis to maintain high levels of energy for growth. Maintaining a healthy leaf surface is critical for plant health and seed production. Many farmers have been asking when is the best time to apply a fungicide to maximize yield and plant health.
