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.
Knee high by the Fourth of July is the old saying for corn growth. In some cases it may be true this year. But for corn that was planted early, we probably should say tassel by the Fourth of July. Crop growth stages are all across the board in 2016. We will see fungicide applications taking place in July in some areas while in many others, corn and soybeans will have only been in the ground a little over a month.
It’s time to check the success of corn pollination in your fields. Corn across northwest Illinois has experienced ideal weather since the middle of May. We’ve seen good planting conditions, timely rainfall, and above-average temperatures in June that have moved the crop forward. As a result, our pollination window is much earlier than last year.
During July, many farmers usually focus their attention on weather patterns and hope for timely, adequate rainfall. While weather is usually the single largest contributing factor toward final yield, many management practices should still be considered to help maximize and protect your crop’s yield potential.
Our area struggled this spring during crop establishment. We experienced soil-borne fungal diseases and cool air temperatures coupled with lots of rain, which has delayed growth and development. We had about three planting windows. Amazingly, the earliest planted crops (both corn and soybeans) look the best at this time. The fields needing replanting (additional soybean populations) were completed about June 1.
Moving into the summer months, scouting is extremely critical. To maximize yield we need to be looking at the crop and watching what it is telling us. Pay close attention to diseases and nutrient deficiencies. What diseases are starting to show up? Where in the canopy are they? Do you have hybrids that are tolerant to leaf diseases? These questions will help determine if a fungicide application is needed.
Many of you may be considering a fungicide application to your soybean fields this summer. We have seen nice yield increases and return on investment in our Practical Farm Research® studies when implementing this practice. Here are a few tips to help make it successful on your farm.
July is the month that we should be actively scouting our crops for disease and insects. At our Kentucky Practical Farm Research (PFR)® location, we’ve found that the best time to apply fungicide on corn is at the VT growth stage (tassel).
As soybeans move into the reproductive phase, many ask if there are in-season nutrient applications that will enhance yield. Although soybeans will sometimes respond to foliar fertilizer applications, this is often because soil availability, root interception, and uptake of essential nutrients is limited.
