Controlling Waterhemp with the RR2X System

The Keys to Success

Author: Joe Bolte

University data has shown that soybean yields can be reduced by up to 35% due to competition with weeds. Problematic weeds such as waterhemp can produce over 800,000 seeds/plant while marestail can produce over 200,000 seeds/plant. Therefore, a handful of escapes can lead to a substantial increase in the seed bank, making future management more difficult and putting weed control at the top of farmers' minds.

Agronomy Talk: PHYTOPHTHORA ROOT AND STEM ROT

Phytophthora root and stem rot is a common soil-borne disease in soybeans that is caused by the watermold, Phytophthora sojae. Phytophthora often occurs in poorly drained soils; it is most economically damaging in low-lying areas and fields that are prone to flooding.

Agronomy Talk: EAR DEFORMITIES

Ear and kernel development is a lengthy process for a corn plant. It begins at the V5 growth stage as the plant determines kernel rows around and then continues to V12 where the potential maximum length of the ear is determined. Next comes the pollination stages where the maximum number of kernels is established and then finally, R5 when the maximum kernel size is established.

Any stresses, natural or manmade, during this process, can lead to abnormal ear set. Many of the abnormal ears and their causes are detailed below. Accurate diagnosis of these abnormalities can help prevent future problems in the field.

Agronomy Talk: Soybean Gall Midge

Author: Pat Holloway

Soybean gall midge is a new pest in soybeans, first documented in Nebraska in 2011 and South Dakota in 2015. In 2018, damage was documented in 66 counties in four states (Nebraska, Iowa, South Dakota, and Minnesota) with that number increasing by 19 additional counties so far in 2019 including the northwest corner of Missouri. It was not until the fall of 2018 that the species was identified.

Agronomy Talk: Harvesting Down Corn

Author: Jon Skinner

Harvesting downed corn is one of the worst jobs on the farm. Year in and year out, there are many abiotic stresses or plant pathogens that will affect standability and ease of harvesting a corn crop. One of the most prevalent issues causing decreased standability of corn is the presence of crown rot and stalk rots. These diseases take advantage of compromised stalk tissue, and degrading it below the ear causing lodging and stalk breakage. There are, however, ways to improve the process of harvesting downed corn that can make it much smoother.

Agronomy Talk: Short Husking

Author: Eric Wilson

Short husking is best described as “corn ears outgrowing their husks.” It results in more exposure of the ear tips to environmental conditions and increases the potential for reduced grain quality.

Agronomy Talk: Ear Drop

Author: Luke Schulte

Ears on the ground prior to harvest is frustrating and often misunderstood. Pest damage, weather stress, reduced nitrogen (N) uptake, and genetics can all contribute to dropped ears. However, identifying the causal agent may help you implement strategies and management practices to minimize ear drop in the future.

Agronomy Talk: Harvesting Corn for Silage

Author: Ben Puestow

Planting delays, poor ear formation, and lack of standability are just a few reasons why some farmers may want to consider taking their corn crop for silage. When making this decision, there are a few factors to keep in mind. These include how to optimize silage quality, tonnage, agronomics, and pricing of the crop.

Agronomy Talk: LATE-SEASON SOYBEAN GROWTH AND DEVELOPMENT

The initiation of flowering on a soybean means that the plant is transitioning into the reproductive growth stage. Most full-season soybeans enter reproductive growth approximately 45 to 55 days after planting. Double crop soybeans will typically enter reproductive growth approximately 34 to 38 days after planting. During this time, the plant has the ability to compensate for any plant injury or adverse growing conditions. Soybeans are prolific flower producers, although more than half are typically aborted prior to pod development.

Agronomy Talk: Corn Rootworm

Author: Nate Mayer

Corn rootworm (CRW) is a pest that, if left unmanaged, can cause economic damage in most of the Corn Belt. Damage can result from root-feeding while they are in larval form and from adult beetles clipping silks during pollination.

Agronomy Talk: Green Snap in Corn

Author: Pat Holloway

Green snap, also called brittle snap, is the breakage of a corn plant usually prior to tassel during the rapid growth period of corn from about the V5 (5 visible leaf collars) – R2 (silk).

Agronomy Update: IRON DEFICIENCY CHLORSIS (IDC)

Author: Mike Blaine

Iron deficiency chlorosis (IDC) is a physiological disorder caused by a lack of iron in the soybean plant which creates the “chlorosis” symptoms. Plants with IDC have yellowing (chlorosis) beginning between the veins and progressing to a generally chlorotic canopy. Other symptoms include reduced plant growth and ultimately, lower yields. Yield reductions from IDC are a primary limitation for some farmers in certain fields.

Agronomy Talk: Crown Rot

Author: Luke Schulte

Crown rot infections are caused by both fusarium and pythium species. These fungi enter the plant via the root system during periods of prolonged saturation, predominately between the V2 and V7 growth stage. Because these fungi persist in higher moisture environments, infections are more prevalent in wetter soils, tighter clay soil textures, higher magnesium soils, and ponded areas of fields. While these infections occur early in corn development, they can persist much longer as the visual signs are not easily detected until later in the grain fill period.

Agronomy Talk: Sudden Death Syndrome

Author: Mike Blaine

Sudden Death Syndrome (SDS), caused by Fusarium virguliforme, is a soybean disease that has grown in importance for farmers over the past 20 years. Today, it is ranked second only to soybean cyst nematode (SCN) as the most detrimental cause of annual damage to soybean yields. As the soybean-growing region has expanded to the North and the West, SDS continues to spread to new fields and to larger areas of fields that have already been infected. The severity of SDS damage varies from area to area and field to field, but yield reductions associated with SDS typically range anywhere from 20 to 70%.

Agronomy Talk: White Mold in Soybeans

Author: Eric Wilson

White Mold (a.k.a. sclerotinia stem rot) is a disease caused by the pathogen Sclerotinia sclerotiorum, and if present, can devastate soybean yield. Farmers are often faced with making management decisions that leave them choosing between what is best for disease management and what is best for maximum yield potential.

Agronomy Talk: Late-Planted Corn

Author: Luke Schulte

Broad areas of the Corn Belt have experienced one of the most challenging planting season in recent memory. Farmers did what they do best, and bided their time for a planting window. Corn acres from South Dakota to Ohio were planted weeks later than what is typical. And while many farmers are already worn out from the extended planting season, most are more nervous about what’s to come.

The good news is that late planted acres still have great yield potential. If Mother Nature starts cooperating, this season has abundant hope of producing competitive yields.

Agronomy Talk: Tissue Testing

Author: Ben Puestow

Tissue testing is an excellent tool for fine-tuning your nutrient management plans and helping to push yields to the next level. Tissue sampling should be done regularly to identify and track any deficiencies or imbalances, and it can also be used as a method for diagnosing problems within a field.
