Soybean Seed Treatment Data,  12/28/17 5:00:52 PM

Soybean Seed Treatment Data—Below is the latest chapter in our soybean seed treatment story. This includes the average test results for the past 9 years. Agronomically, we think seed treatments are a standard item you should consider using every year. Yes, with later planted (May to June) soybeans, seed treatments lose a bit of their luster. However, economically, in a down commodity market, you may consider this cost as one you might remove to save a few dollars per acre. Given the results of the past 9 years, it is hard to argue the return on your investment. These are multiple treatment tests vs. the untreated check of the same genetics. The following table looks at one consistent treatment across all years vs. the untreated check. Here is our current data:

What about Ilevo?  Using Bayer’s promotional material as a reference, they state:
 
 The results are clear – ILeVO® leads to greater soybean yields.

ILeVO seed treatment is the only product that offers effective protection against 
Sudden Death Syndrome (SDS) and nematodes in the seed zone, resulting in healthier plants and higher yield potential.

 
  • In 6 years of testing with 337 comparisons, ILeVO provides an average yield increase of 4.7 bu./A vs fungicide/insecticide base with a positive yield response 84% of the time. The yield advantage from ILeVO increases with higher levels of foliar SDS symptoms.
SDS continues to be a major issue in soybean-growing regions. Once the soilborne fungus causing SDS is present in a field, it does not go away and can be spread by soil movement to neighboring fields.
ILeVO is the only product that protects against both the 
root rot and foliar phases of SDS, making it the most complete SDS protection available on the market. In fields that have been infected with SDS, ILeVO has been shown to be effective in helping minimize the impact of the disease on yield loss.
Nematodes cause significant yield loss every year across all soybean-producing geographies. 
Soybean Cyst Nematode (SCN) causes more yield loss in soybeans than any other pest. Complementing nematode-resistant soybeans with ILeVO adds another level of protection that results in reduced nematode damage and increased yield potential.
ILeVO protects against key pests in opposing weather conditions. While nematode damage increases in hot, dry conditions, SDS thrives in cool, wet conditions. With ILeVO, your soybean crop is protected against both.
For the best in soybean protection, 
pair ILeVO with Poncho/VOTiVO for unmatched control of the SDS fungus, nematodes and insects

 
Although there is a marketing “spin” to the above statements, much of what is stated is true.  In our opinion Ilevo is the current industry leader when it comes to helping control SDS in soybeans.  SDS and SCN infestations have commonly been linked together and though no academics will confirm this thought, it would certainly make sense that if you have had SCN issues then there is likely an increased chance of SDS pressure   WHY??  Remember that Sudden Death Syndrome is caused by Fusarium solani f. sp. glycinea. It is a soil borne form of fusarium that attacks the soybean tap root.  It causes the tap root to become very discolored and there are few, if any, secondary roots. A blue stain may be present on the root. The pith is white. As leaves drop, petioles will remain attached to the plant.    I mention all of this to bring out the consideration that anything that attacks the soybean root system (SCN), those affected plants would LIKELY be more susceptible to the affects of an SDS infection.
Ilevo combined with either Cruiser Max Advanced or Acceleron Complete has been our best yielding seed treatment for the past 2 years.  Our data does not have near the 336 sites that are mentioned and also does not have that much (4.7 bu./acre) of a yield advantage, however, it is the best yielding seed treatment we have tested.  The only problem is that we cannot make the economics of the combined seed treatment work on an annual basis, across all testing environments, to recommend it as a consideration for your soybean purchases.  This is largely due to the fact that there are inconsistent levels of SCN/SDS present in our testing areas.  That is great for the producer, but, hard to develop and consistent message surrounding merits of this type of treatment.  Now, IF you have had a history of SCN and ALSO a SDS problem, then the economic return picture drastically changes and you can likely afford the added seed costs associated with the combined seed treatment.
