Herbicide Programs

While the snow has put a stop to most of the harvest and fieldwork in the area, farmers are still busy making decisions for their operations. While applications won’t be made for several months, now is a great time to plan next year’s herbicide program for your corn and soybeans.

The first step in making an effective herbicide program is to know and understand what weeds are present and will cause issues in your fields. Understanding the life cycle, germination timing and any resistance to herbicides is important in putting together a successful plan. Read the full article>

Fall Anhydrous

As harvest winds down, many farmers in the area will begin applications of anhydrous ammonia before the frozen ground forces them to park their tractors for the winter. While this is a wide spread practice, fall nitrogen applications carry risks of being lost before being used by next year’s corn crop.

What makes fall applications of anhydrous ammonia risky are unknown weather conditions that may lead to nitrogen loss before spring. Nitrification is a process driven by microbes in the soil. Therefore, when little microbial activity is occurring, such as when the ground is frozen, nitrogen in the ammonium form is safe from losses. However, warm temperatures and moist soils increase nitrification and make it more likely that some applied nitrogen is lost before the corn crop has a chance to use it.  Read the full article>

Fall Herbicide

Winter annual weeds cause problems for row-crop farmers across Missouri every spring. There’s still time to make herbicide applications this fall to control weeds before they cause you problems next planting season.

A winter annual weed is a weed that generally germinates in the fall, goes dormant over the winter, then resumes growth and completes its life cycle in the spring. A number of producers have asked whether or not they should use a residual herbicide in their application.  This largely depends on the timing of the application and next crop to be grown.

Soybean Sprouting in Pods

Rains throughout the region over the past two weeks have provided relief from the drought we endured throughout the summer. While ponds and pastures were able to benefit from the moisture, soybeans in the field were past the point of benefitting from the rain, and may suffer yield losses as a result. Full article>

Cercospora Leaf Blight

Producers may be surprised this fall when they look in their hoppers and see soybeans with large purple spots. This is the result of a fungus called Cercospora kikuchii, which can infect soybean seeds, pods stems and leaves. It is commonly referred to as Cercospora leaf blight or purple seed stain.

Spiny Amaranth

Spiny amaranth, or spiny pigweed, is a weed that has been showing up in greater numbers in Missouri pastures recently. As its name suggests, the weed has two spines at each node, making cattle and other livestock avoid the plant while grazing. If allowed to become established in a pasture, it is extremely difficult to eliminate this weed. To learn more>

Aflatoxins

Several farmers in the area have been concerned about aflatoxin levels in their corn this year. While I have not heard reports of aflatoxins being present yet, weather conditions this summer do increase the possibility that this could be an issue during harvest. Full article>

Herbicide Carryover

As we near the end of August we are getting to the time of year when many producers begin to plant cover crops on their farms. Cover crops can prevent soil erosion, supply nutrients to the following crop, suppress weeds and reduce soil compaction at a time when most fields are fallow. If you are going to plant cover crops on your farm, be aware that some herbicides used during the previous crop cycle may still be present in the field and may prevent your cover crops from becoming established.

Baling Soybeans-Fall Fertilizer

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. More

Nitrates and Silage

Many questions have come into the office recently about cutting drought-stressed corn for silage. These questions usually deal with nitrate levels in corn as well as the right moisture content to make silage.

Nitrates accumulate in the stalks of drought-stressed corn. Higher levels of nitrate are found primarily in the lower portion of the stalk, while corn leaves will not accumulate any nitrates. Following a rainfall event, nitrate levels in the corn plant will spike as the plant takes up more nitrogen from the soil. Fields where higher levels of nitrogen fertilizer was added will be more at risk for higher nitrate levels in the plant.

If you are planning to cut drought-stressed corn for silage, contact Andy Luke, regional agronomy specialist, at 660-425-6434 or your local University of Missouri Extension center to have your corn spot tested for nitrates. To learn more>
