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.

KENTUCKY AND TENNESSEE - AUSTIN SCOTT, CCA

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.

NE ILLINOIS, NW INDIANA, SE WISCONSIN - CHAD KALAHER, CCA

Next Steps for Corn and Soybean Crops

Author: Chad Kalaher

A significant amount of corn was planted into good conditions across the majority of our geography between April 14 and 19. Soil temperatures were adequate and trended upward to support excellent germination and rapid emergence. During the last week of April, air and ground temperatures cooled, with many areas receiving rainfall. Early stand counts and root development in corn were excellent.

Wheat Harvest and Double Crop Soybeans

As June rolls around here in southern Illinois, I start to think about wheat harvest and getting double-crop soybeans planted. It has been an interesting wheat year to say the least, but aren’t they all? In some areas of southern Illinois we dealt with stripe rust, which meant spending a lot of hours walking wheat fields in late April and early May.

Scouting Fields for Stressors

Author: Wade Kent

As crops reach their reproductive stages, it is important to know what stressors may be lurking in your field. Diligent scouting is critical to maintaining high yield at harvest. It can be difficult and sometimes time consuming, but the commitment can have a great impact on your bottom line.

Managing Foliar Diseases

Author: Pat Holloway

Depending on planting dates and growing conditions this year, both corn and soybeans will begin their reproductive growth stages toward the end of June and into July. This is a critical time to manage foliar diseases. Each growing season is unique in the weather patterns we see and ultimately which diseases we need to be most concerned about.

Wheat Harvest + Double Crop Soybeans

Author: Steve Gauck

With wheat harvest officially underway across southern Indiana, I wanted to offer you a few tips about harvest and planting double crop soybeans.

When preparing to harvest wheat, the ideal moisture is between 14 to 20 percent. Below 14 percent moisture we start to see yield loss and we could also run the risk of a rain lowering test weight and quality. Air drying wheat will give you the best quality. For long-term storage, make sure to dry your wheat to 12.5 percent moisture.
