Managing those Double-Crop Beans

Got your double-crop beans planted? What should you pay attention to next? As we move into the middle of July now is the time to pay special attention to your double-crop soybeans. July often is a critical time in the life of a double-crop soybean because of many factors.  And some of those factors can play havoc, not only with your double-crop beans this year, but also with the corn crop planted next year on those same acres. The biggest factor right now on the double-crops is the weather. In many places in Southern Illinois we are very hot [...]

PODCAST: Fungicide Timing and Use in Production

Managing soybean diseases starts with knowing what to look for locally. In this latest podcast, Beck’s Hybrids agronomist Chad Kalaher talks about soybean diseases that are common in Illinois and how to employ proper fungicide management. In all of Illinois Septoria brown spot is tagged as the number 2 yield robber in soybeans. It progresses from the bottom of the plant and is a disease that soybean farmers should look out for. In addition, northern Illinois farmers should watch for white mold, while Southern Illinois farmers should watch for frogeye leaf spot. It’s important to note that not all [...]

Seeing Postemergence Problems in Soybeans

Weeds are tough enough to control today. Throw in weather-related issues and it’s a recipe for disaster. This is the year we can all learn from our experiences with so-called “resistant/tolerant weeds.”  I have been experimenting with many different combinations of chemicals to find the most effective suppression, because I do not think we will ever have full control of these most troublesome weeds. First and foremost, we need to begin targeting each weed individually, instead of a blanket chemical program across all acres. This means we need to map and record each field and identify the weeds that [...]

Does Poor Soil Fertility Contribute to SDS Outbreak?

Will high soil test K levels protect against SDS or other diseases?  More is not always better. With nutrient deficiencies becoming more commonplace, we are often reminded of the need to keep adequate levels, as well as the correct application timing, of macronutrients and micronutrients to supply the proper nutrition needed for optimal performance of today’s higher yielding soybean varieties. Dan Davidson recently reviewed soybean potassium (K) deficiency. But what happens when your soil test reveals that you have high levels of K available in your soil? This nutrient is known for promoting stem and root growth as well [...]

Dicamba Technology Demands Multiple Levels of Stewardship

Nearly every new technology brings its own challenges and learning curve—and the first full season with dicamba-tolerant soybeans and approved over-the-top herbicide formulations is a reminder of that fact for farmers, researchers, ag retailers and farm organizations. With the new dicamba-based herbicides under a two-year U.S. EPA label, and with weed management challenges growing every day, it’s essential for the industry to get this right. Everyone involved with production agriculture has a critical role to play in the proper stewardship of these new products, including strict adherence to all label guidelines. ISA, along with Illinois Farm Bureau (ILFB) and [...]

Symptoms to Look for In July

When scouting fields in July, look for these symptoms. They may be big problems or really no problems at all. As we move further in the growing season and start scouting soybean fields we may see symptoms of disease, insect infestation or environmental conditions. Some are easily recognized while others can be confused with something else. Some symptoms are more uncommon and not seen every year. Below is a guide of soybean symptoms that are starting to become common in this year of uncommon growing conditions. Sunscald is natural phenomena often associated with a swing of approximately 30° F [...]

Soybeans Can Handle Mid-Summer Stress

So, what happens to soybean plants that are stressed during the summer? The 2017 season has been stressful and July looks to be warmer and drier than normal. First it was wet and cold early this spring, which prevented planting or stressed emerging soybean seedlings. When they finally got planted it turned dry and hot. Soybean development is behind and plants are smaller than they normally would be by now. However, they are tolerating the conditions quite well according the weekly USDA National Agricultural Statistics Service (NASS) crop condition report. Nearly 60 percent of the soybeans were rated as [...]

Nodules on Soybean Roots

Soybean plants have the ability to form a symbiotic relationship with nitrogen-fixing Rhizobia bacteria, which cause the small swellings on the root system called nodules. The soybean plants are developing rapidly and nodules will start to form shortly after plant emergence. If the plant is around 6 inches tall with the first or second true leaves (trifoliolate leaves) unfolded, nodules will start to actively fix Nitrogen (N) gas into plant available N. The number of nodules will increase until the R5 (the beginning of the seed formation) stage or slightly beyond. In Figure 1, the average number of soybean [...]

Path to Higher Yields

Combining strategies will produce higher soybean yields. Obtaining higher soybean yields is a great goal. However, the true challenge is doing it sustainably and profitably, year after year and beyond. Think of each soybean plant as a factory. As with any factory, it’s all about how efficiently the factory produces an output and overcomes its potential limiting factors. When evaluating a soybean plant or “soybean seed factory,” its efficiency and limiting factors can be determined by a mathematic formula: Yield = Pod/Acre x Beans/Pod x Weight/Bean. Several production concepts are being evaluated and will be on display at the [...]

Foliar Feeding Soybeans

What makes a good formulation for foliar feeding soybeans? There has been a lot of interest in foliar feeding soybeans since the runup in soybean prices a decade ago. Growers have appreciated that the technology has increased soybean yields and are a bit reluctant to go back to the old ways of not investing in soybeans. However, there is no single perfect product out there. With multiple brands and products, and many look-alike products available from different suppliers, the market is crowded and often confusing. One new practice is foliar feeding soybeans in season. We know that soybeans require [...]
