Baling Soybeans-Fall Fertilizer

BETHANY, MO-The prolonged drought in Northwest Missouri has forced many farmers to consider baling their soybeans as a forage crop this year. While soybeans are an excellent feed source for cattle, producers need to take into consideration the herbicides that were sprayed on the soybeans throughout the growing season. Some herbicides such as Roundup and Sencor have pre-harvest application intervals of less than 30 days, allowing the soybeans to be cut or grazed after this time period. Most herbicides though, such as Liberty, dicamba products and most residual herbicides are not allowed to be grazed or harvested for forage or hay. Be sure to read and follow all label directions before harvesting soybeans that have been treated with herbicides.

 

An alternative source of forage this fall would be grazing hay fields or other areas with established stands of perennial grasses. Most pastures and hayfields in the area are seeded with cool-season grasses such as tall fescue or brome. These grasses will produce most of their annual growth during the cool spring months before going nearly dormant during the hot summer. With cool fall temperatures, additional grass growth can be expected in late August and September. To encourage additional growth, consider adding nitrogen or phosphorus to your hayfields to give the grass an additional boost. Nitrogen can improve both yield and protein content of grass, while also making the plants more vigorous, leading to thicker stands. Phosphorus is essential for root growth and development, especially in new or damaged grass pastures. In a year such as this, adding phosphorus to pastures that have been over-grazed may lead to additional grass growth this fall and next spring. Before adding phosphorus, consider getting a soil test to know the nutrient levels of your fields. Also, keep in mind that fertilizer that has been broadcast will require up to ½ of an inch of rainfall to be incorporated into the soil. Try to time your fertilizer application before a rainfall event to prevent fertilizer losses

Dicamba

New Training Requirements for Soybean Herbicides Containing Dicamba

The EPA approved new herbicide labeling as of October of 2017  and has major changes. Please study the labels on the Missouri Department of Ag website for the Federal label and 24c label, which is Missouri specific.

Growers and certified applicators who will be applying the product will be required to have a private pesticide applicator license. Each person applying the product will be required to have the license rather than working under a growers license.

Also, private applicator licenses from other states than Missouri are not acceptable. The private pesticide applicator license must be a Missouri license.

Secondly, auxin herbicide training which is the new training requirements including dicamba are required. This training can be accessed on-line through the Missouri Department of Ag website or the University of Missouri Extension website and searching for “Synthetic Auxin Herbicide Applicator Training Program”

MU To Offer Dicamba Training

COLUMBIA, Mo. – Dicamba application has presented challenges for Missouri agriculture, and the University of Missouri recognizes the importance of preparing our communities for managing this and similar technologies in the future.

Beginning in December 2017, the MU College of Agriculture, Food and Natural Resources, and MU Extension, in cooperation with the Missouri Department of Agriculture, will offer web-based and in-person training for those wishing to use or purchase dicamba in 2018. More information will be available at extension.missouri.edu/main/spotlight/dicamba.aspx.

On Oct. 13 the Environmental Protection Agency announced an agreement with Monsanto, BASF and DuPont on measures to minimize the potential for off-target movement of dicamba and further ensure effective use of three pesticides: DuPont’s FeXapan, BASF’s Engenia and Monsanto’s XtendiMax. The Missouri Department of Agriculture is reviewing these requirements as preparations are made for the 2018 growing season. The department is also working with MU and other researchers to strengthen education and training specific to dicamba and other auxin herbicides.

The full news release from the EPA is available at epa.gov/newsreleases/epa-and-states-collective-efforts-lead-regulatory-action-dicamba.

More information about dicamba is available at Agriculture.Mo.Gov/dicamba.

MU Variety Testing Program

The Missouri Crop Performance corn and soybean test results are available at your local extension office for free. When using the data, look at the sites across northern Missouri which represent different yield environments. Different yield environments provide an opportunity to see how a hybrid or variety will perform with different weather risks. Stop by your local extension office and pick up your free copy. For more information, contact MU Extension regional agronomist, Wayne Flanary at 660-446-3724.

Crop performance results are also available online from the MU Variety Testing Program.
