Current Crop Scouting Report

Fields scouted NE of Liberal and south of Mindenmines on August 24th.

Corn in the milk stage. Southern rust has been confirmed in SW Missouri in Barton County. Gray leaf spot is in all fields scouted. When considering a fungicide, leaves at and above the ear are most important to protect. Leaves at ear level and above are responsible for at least 60 percent of grain fill- https://www.agry.purdue.edu/ext/corn/news/timeless/GrainFill.html Given the wet conditions, consider a fungicide at tassel. It is important to differentiate between common and southern rust, as southern rust can cause significant yield loss. Common rust has brick red pustules, sparsely scattered on the upper and lower leaf surface. Southern rust has orange pustules, densely clustered on the upper leaf surface only. Mid-May or later planted corn is at higher risk for yield reduction from southern rust. Fungicide applications for southern rust are beneficial even with corn in the milk stages.

In flying over Missouri, Peter Scharf, MU state fertility specialists estimates SW Missouri has had the most nitrogen loss, and estimated a 20 bushel/acre yield reduction. 

Soybeans ranged from emerging to early bloom. Less than 5% foliage feeding was observed. Threshold level for all foliage feeding insects in soybeans are 30% defoliation before bloom and 20% defoliation during or after bloom. Small water hemp was present in most fields, for most effective control, treat weeds when they are 2-4” in height or diameter.

Health tip: In general, sunscreen is effective for up to 3 years. It is recommended to wear a minimum SPF of 30.

Fields checked near Avillaon on August 17th.

Soybeans in the first trifoliate, some scattered plants throughout the field were clipped. Insects were not present at the time; when looking for caterpillars, look for holes near the plant and carefully dig in the soil up to 2” deep around the plant to find them.

If considering replanting soybeans keep in mind that hard rainfall events after planting (especially in tilled fields) can cause a crusting which can affect soybean emergence. Watch the weather forecast prior to planting and don’t plant in too wet of soils.

Corn was in the milk stage. Common rust and gray leaf spot were found. Leaves at and above the ear are most important for yield. If disease is present on these leaves in a dense amount, consider a fungicide.

Southern rust has been confirmed in SE MO and SE KS. Mid-May or later planted corn is at higher risk for yield loss from southern rust. When scouting for rust, common rust will typically be on the upper and lower leaf surface, and pustules are brick red, southern rust is only on the upper leaf surface, with orange colored pustules.  Follow the southern rust movement at https://corn.ipmpipe.org/southerncornrust/

Keep in mind that late planted corn requires fewer growing degree days to reach maturity than corn planted at optimal time due to the warmer days this time of year. The days to maturity rating on a hybrid does not refer to literal calendar days, it is dependent on temperature. Later planted corn will reach maturity in less calendar days.

Missouri crop performance reports

Finding varieties that best fit a farmer's production goals and challenges is an essential part of profitable grain crop production. MU Variety Testing Program provides the reliable, unbiased, up-to-date information that makes that selection possible.

Each year they test more than 600 corn, grain sorghum, and soybean varieties at 32 locations throughout Missouri. These 32 locations are distributed among four regions: North, Central, Southwest and Southeast. The number of locations within a region depends on the specific test but varies from two to five. Companies enter their varieties into tests at one or more of these regions, but their entries must be placed at all locations within a region.

Headquarters for the MU Variety Testing Program are Bradford Research and Extension Center located in the heart of Missouri six miles east of Columbia. More personnel are located at the Delta Research Center near Portageville and the Hundley-Whaley Center near Albany. The majority of our test locations are farmer fields and we appreciate the cooperation and dedication of our cooperators.

Hay for Sale Listings

These listings are a joint venture of the Missouri Department of Agriculture and the University of Missouri.

The listings include sellers names, cities, counties and phone numbers. Sellers can be listed by either region or forage type. Bale type is included: small square, large square, small round, large round, baleage, or other. The number of bales and approximate weight of each bale of hay is included, and if the hay has been analyzed, crude protein, acid detergent fiber, neutral detergent fiber, relative feed value, and percent total digestible nutrients may be included. A final area for notes catches information such as first cutting or specifics such as call times.
