"Tassel by the Fourth of July"

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.

Scouting the Pollination Progress of Your Corn

Author: Craig Kilby

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.

Management Practices to Protect Your Crop's Yield Potential

Author: Chad Kalaher

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.

Crop Monitoring is Number One Priority

Author: Denny Cobb

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.

Scouting Critical to Maximize Yield

Author: Steve Gauck

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.

Scouting and Fungicide Application Updates

Author: Austin Scott

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).

Soil Testing and Fertilizer Application Programs

Author: David Hughes

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.

Sound Agronomic Decisions Can Improve Profitability

Author: Alex Johnson

While spring and early summer certainly brought some challenges to Ohio farmers, much of the yield potential of our corn and soybean crops is determined during the months of July and August. Even though weather may be the main yield-influencing factor this time of year, there are a few things you can do now to improve profitability.

How to Get the Most Out of Liberty® Herbicide

Author: Austin Scott

At the moment, Liberty® (glufosinate) is the only post-emergence herbicide available to control glyphosate and PPO-resistant Palmer amaranth and waterhemp. So naturally, we need this herbicide to perform to the best of its ability. There are a few things you can do to enhance the efficacy of your LibertyLink® herbicide program. Below I have outlined the best management practices for post-emergence Liberty applications.

Ohio Fields Showing Signs of Phytophthora Root Rot

Author: Mark Apelt

Over the last few days, many farmers in Ohio and eastern Indiana have noticed some patches or large areas that appear to be wilting, turning yellow or brown, and dying. Below are just a few photos of the symptoms we are seeing.

Should You Spray a Fungicide?

Author: Austin Scott

A lot of our early planted corn is already in the reproductive stage, or will be within the next week. A majority of the phone calls I’ve recently received are from farmers asking “should I spray a fungicide?” This is a tricky question. On one hand, you don’t want to throw money at a corn crop when it’s not warranted, but on the other hand you don’t want to lose potential yield by not protecting your crop. So the million-dollar question is, “what should I do?”

Protect Your Corn from Yield Robbing Pests

Author: Jon Skinner

Protecting corn from yield-robbing pests is one of the greatest concerns for farmers each year. From late June to mid-July these pests include foliar diseases and silk clipping insects. Properly managing these pests is crucial, and we can start by getting a better understanding of the economic and agronomic factors of each specific field.

Storm Winds and Heavy Rain Cause Root Lodging in Missouri Fields

Author: David Hughes

We received high storm winds with rainfall Monday night in much of Northern Missouri and there are a lot of acres with corn blown over or down (root lodging). I have not heard of any significant greensnap which is good.

Here are a few key points to remember...

Sugar as a Starter Additive?

Author: Alex Johnson

While reflecting on the months leading up to planting, I realized I received more phone calls and questions on the Starter Additive – Sugar Study at our Ohio Practical Farm Research (PFR)® location than any other study in the PFR Book.

Identifying N-Deficient Areas in Your Corn Fields

Author: David Hughes

The first two to three weeks of June is when I usually conduct flights to secure high-res aerial imagery of corn fields to determine nitrogen (N) health and identify N-deficient areas. Generally, N loss will become more apparent in Missouri corn fields as they reach the Vn to V10 growth stage and leaves close over the row.

To Spray or Not to Spray

Author: Austin Scott

As this growing season progresses, it is important to scout your fields weekly for weeds, insects and disease. Spray only when it is warranted. While preventative spraying can be tempting, it also increases the odds of producing resistant pests.

Scouting for Root Health and Weed Control

Author: Steve Gauck

Scouting is critical to the success of your crop. Now is a great time to evaluate your stands and the job your planter did. As corn reaches the V4 to V6 growth stage, it is transitioning from receiving energy from the seed to getting all of its energy from the roots. Take time to dig plants now and look at the root health.

Addressing Corn Crop Concerns

Author: Denny Cobb

During this time, two major corn crop concerns should be evaluated. The first is stopping first-generation European corn borer (ECB). More unprotected (non-traited or conventional) corn was planted this season than in recent years, creating more host plant acres.
