Storm Damaged Corn

Recent storms have left many fields damaged by hail or floods. When assessing damage, it’s best to wait three to seven days to allow your plants to begin recovery before determining the extent of the injury.

When corn is small, yield or stand loss from hail damage is negligible. In corn plants, the growing point remains underground until approximately the V5 or five leaf growth stage. Most area fields have not yet reached this point, so even complete defoliation is not expected to significantly reduce yield. These fields should recover and should not be replanted or destroyed. For fields past the V5 growth stage, pull and split several plants five to seven days after the storm and determine if the growing point has been damaged. If the growing point remains intact and viable, the plant is expected to survive. Expected yield loss can then be estimated by determining the percent leaf area destroyed and the growth stage of the corn. As an example, 75% leaf defoliation of sixth and seventh leaf plants will result in 5 and 6 percent yield losses, respectively. Read the full article>

Spring Pasture Renovation

As we look forward to warmer weather and longer days, it is no secret that the weather this past year has challenged farmers in the area. As a result, many pastures may be in poor condition heading into the growing months. For farmers who have considered renovating their fescue pastures, the poor pasture conditions may make this a great time to move forward with renovation plans.Full Article>

2019 Insects

Two weeks ago, I talked about new diseases that may show up in Missouri crop fields in 2019. Growers should also be on the lookout for insect pests that may also show up in Missouri for the first time this year. Orange Gall Midge in soybeans is a relatively new pest, with injury first being reported in South Dakota in 2015. Appearing originally as small, white larvae, the gall midge turns bright red or orange as it matures. Read the full article

New Pests Could Emerge in 2019

Like any New Year, 2019 will also come with new challenges. For farmers, these challenges may show up as pests new to Missouri for the first time in 2019. Now is a great time to learn about these pests so we are prepared when they show up during the growing season. To learn more>

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>

Coping with Disaster

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>
