With the rough start to our region’s growing season, we need to start thinking about keeping our fields strong and healthy all the way to harvest. With favorable weather this growing season we still have the potential to grow a high yielding crop, despite being planted late. Below are fungicide efficacy ratings for several products out on the market, as well as a link to the UNL plant disease website. If you have any questions regarding disease problems in your fields, contact your Hoegemeyer product agronomist for help determining the best plan of action.
Planting is well underway in the Hoegemeyer footprint and we have corn anywhere from seven leaves or more in Oklahoma to seed that still needs to get in the ground. I have been travelling and looking at fields over the last two weeks across Nebraska, Kansas, Missouri and South Dakota. All areas have had one thing in common — an abundance of moisture. In fields where water could drain, we are seeing some excellent stands in our Hoegemeyer products. In areas where water ponded and low lying fields are the fields where we are seeing some stand issues. Also, some fields planted on Friday, April 15, and Saturday, April 16, seems to be suffering from imbibitional chilling injury. Most of the Hoegemeyer footprint received substantial rain on Sunday, April 17, causing cold and saturated soils. These cold, saturated conditions have caused plants in several fields to leaf out underground resulting in stand loss. Aside from a few stand issues, the 2016 crop just needs a little heat and sunshine, and it will be off to the races. Now is the time to be scouting your fields for stand establishment issues to make sure to set yourself up for a successful harvest. If you have any questions or issues, contact your local Hoegemeyer DSM or Agronomist.
Hoegemeyer believes in seed treatments as a means to capture greater yield by protecting the soybean seed from the start. Whether it’s on your own acres or when going up against the competition, Right Stand® and Right Stand + ILeVO® treatment packages protect the genetic potential on every seed, every bag and every acre!
Here's a few reasons why:
Wider Planting Window
Planting in cool, wet soils may result in slower emergence.
Increased disease pressure is possible.
Seed treatments allow for earlier planting dates and reduced replant.
Tolerance to High Residue Environments
Increased soil residues can harbor pest populations and disease pathogens.
Residue is associated with cool soil temperatures which may delay emergence.
Improved Soybean Plant Performance
Pest and Disease control
2.5 bushel average yield advantage for Right Stand over no treatment.
2-10 bushel yield advantage for Right Stand + ILeVO over base package depending on severity of SDS and SCN pressure.
Right Stand and Right Stand + ILeVO soybean seed treatment is a proprietary mix of chemistries including an insecticide, biological growth stimulant, and multiple fungicides offering broad spectrum protection. A common misconception is that seed treatments are only needed for early planting dates. Some insects and diseases are not limited to cool and wet conditions associated with early planting dates. An example would be Phytophthora Root Rot which is also very active under warm and wet soil conditions.
If you have any questions about soybean seed treatments, visit your Hoegemeyer DSM, Dealer or Agronomist.

Sudden Death Syndrome (SDS) is a fungal disease that affects soybeans. Several fields in Southeast Nebraska, Northeast Kansas, Northwest Missouri, and Iowa are showing signs of SDS. SDS was first reported in Arkansas in 1971. It can now be found in almost all soybeans growing areas in the U.S.
SDS is a soil-borne pathogen that infects soybean seedlings when they are emerging. Producers won’t typically see any symptoms until late July into early August. Early symptoms include interveinal chlorosis and necrosis.

The disease will eventually lead to plant death which is the main cause of yield loss. In most cases, the leaflets will drop off, but the petioles will stay attached. In fields where there is adequate moisture there will also be small patches of blue fungal spores around the soil line.
There are a few different ways to manage for SDS.
The first way to help manage for SDS is to plant later. The disease typically infects in cool, wet soils more typically associated with planting early so pushing the planting date back is one management tool.
Tillage is another tool that can be used to help reduce SDS. Compacted soils will slow water infiltration and cause soil saturation which will increase SDS incidence.
Planting resistant varieties is a third management strategy to reduce SDS. Varieties vary greatly in the tolerance to SDS and a good resistant variety is a good way to ensure SDS doesn’t rob too much yield.
SO WHAT IF YOU DON'T WANT TO CHANGE YOUR PRODUCTION PRACTICES?
New for the 2016 growing season Hoegemeyer will be selling a seed treatment that is specific to SDS. The product called ILeVO will be a seed applied fungicide that specifically targets SDS. The product has shown very good results the last two years and looks promising again this year. This is a side-by-side of the same variety where the left was untreated and the right was treated with ILeVO.
Talk to your local Hogemeyer DSM or Agronomist if you have any questions about SDS and plan to use ILeVO to boost your yields in fields where SDS is a problem.
It may be a bit too early to accurately predict the potential for significant foliar fungal diseases in this year’s crop. However, the agronomy team at Hoegemeyer will be keeping a close eye on disease development in the days and weeks leading up to tasseling. The summer of 2014 saw an unusually high amount of foliar disease in corn, especially in Iowa, eastern Nebraska, and northwestern Missouri. Last year’s months of May and June were filled with consecutive days of rain and moderate-to-below normal temperatures. This set us up for the presence of a foliar disease called Northern Corn Leaf Blight (NCLB) which is normally confined to the central and eastern corn belt. The disease itself can be fairly aggressive if conditions remain favorable for infection, especially in hybrids that are susceptible. High risk fields would include those with high amounts of corn residue, fields with a history of the disease in 2014 and especially those with average-to-below average Northern Leaf Blight ratings.
2015 has been somewhat déjà vu in regards to the late May and early June weather patterns. Very recently, there have been reports of suspected Northern Leaf Blight in fields in eastern Nebraska. The good news is that it appears we may finally break into a somewhat more normal summer weather pattern with temps climbing well into the 80’s with 90’s in the 7 day forecast. This disease will struggle to infect and progress with these warmer temps. However, it is possible infection has already occurred in some fields.
Growers are encouraged to consult with their Hoegemeyer District Sales Manager and/or Hoegemeyer Agronomist(s) as we approach the optimum period for fungicide applications which is typically VT (tassel) to R2 (blister). It will pay to begin checking fields starting now. Several foliar fungicides have good activity against this disease as well as others. If specifically targeting Northern Leaf Blight, one does not want to delay the decision to spray if the disease is present. Last year there were likely several fields that were sprayed too late and did not benefit fully from the fungicide application.
A follow up informational blog will be posted on this topic again within the next 2 weeks as we are better able to evaluate potential foliar disease development in this year’s corn crop.
