ILEVO® Seed Treatment
ILEVO seed treatment has an unmatched track record of success. In more than 350 field trials across a variety of conditions, ILEVO seed treatment had an 84% positive yield response, with a 4.6 bu/A average yield gain compared with a fungicide and insecticide base. The yield advantage from ILEVO seed treatment 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. In fields that have been infected with SDS, ILEVO seed treatment has been shown to be effective in helping minimize the impact of the disease on yield loss.
ILEVO seed treatment 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 seed treatment has been shown to be effective in helping minimize the impact of the disease on yield loss.
The performance of ILEVO seed treatment has been proven in field after field after field:
The yield advantage from ILEVO seed treatment increases with higher levels of foliar SDS symptoms.
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 seed treatment adds another level of protection that results in reduced nematode damage and increased yield potential.
With the unpredictability each season brings, ILEVO seed treatment protects against key pests in opposing weather conditions. While nematode damage increases in hot, dry conditions, SDS thrives in cool, wet conditions. With ILEVO seed treatment, your soybean crop is protected against both, no matter the conditions.

The list of pests controlled by this product is from the Environmental Protection Agency-approved Federal Label. Please click on 'Labels / MSDS' below for special or state-labeled pests. Always read and follow label instructions.
Septoria Brown Spot: (Early season) (Septoria glycines), Soilborne nematodes: Lance nematodes (Hoplolaimus spp.), Reinform nematode (Rotylenchulus reniformis), Root-knot nematode (Meloidogyne incognita), Root lesion nematodes (Pratylenchus spp.), Soybean cyst nematode (Heterodera glycines), Sudden Death Syndrome (SDS) (caused by Fusarium virguliforme)
Prepare for SDS Early in the Season
According to University of Illinois research, the initial SDS infections that occur on the roots and crowns of young soybean plants occur as early as the seedling stage. Roots have a blue coloration when infected and subsequent Root rot affects seedling health.
Sudden Death Syndrome (SDS) is one of the top yield-robbing pests in soybeans. Over the last five years, average annual damage caused by SDS cost soybean growers more than 44 million bushels in lost yield, and the spread of the disease continues to climb. SDS has been documented in almost every state where soybeans are grown. And while reported losses often represent 20-30 percent of a crop, yields can be cut by more than 70 percent.
Melissa Chu, ILEVO seed treatment product manager, urges growers to pay attention to the possibility of SDS in their field. Once SDS is in a field, it stays there, and it’s a disease growers have been fighting for decades. Studies at Southern Illinois University Carbondale confirmed greater soil compaction leads to higher levels of SDS.
At flowering, the SDS fungus produces toxins that cause foliar destruction, including leaf drop and aborted pods. Plants may pull easily from the soil. Soybean stem tissue turns white, while areas between leaf veins turn bright yellow and then brown. The brown tissue may fall out and leave large holes in the leaves. Toxin production and symptom severity will vary by climatic conditions and the level of SDS resistance in the varieties grown.
ILEVO seed treatment is unique in that it protects against both the foliar (above-ground) and root-rot (below-ground) phases of the disease, making it the most complete SDS protection available on the market. In addition, ILEVO seed treatment provides broad-spectrum protection against all plant-parasitic nematode species in the seed zone, including Soybean Cyst Nematode (SCN), which, when present in a field, can exacerbate the SDS disease.
Field trials show yield are 2-10 bushels per acre higher when ILEVO seed treatment is used, depending on pest severity.
ILEVO seed treatment is the only product that offers effective protection against both Sudden Death Syndrome (SDS) and nematodes in the seed zone. It protects the soybean root system against the fungus causing SDS and against nematodes including soybean cyst nematode (SCN), root-knot nematode (RKN), reniform and lesion in the seed zone, producing healthier plants for higher yield potential.
In most instances, growers will see the Halo Effect – a visual confirmation that ILEVO seed treatment is working to protect the plant. The Halo Effect is a discoloration that appears on the edge of the cotyledons, appearing first as light green to yellow to brown as the seedling emerges. The discoloration is limited to the cotyledons and does not appear on the unifoliates or trifoliates.
The Halo Effect is an indication that ILEVO seed treatment is being localized in the soybean root and seedling where it is needed for protection against the fungus causing SDS and against nematodes.
Frequently Asked Questions About the Halo Effect and ILEVO seed treatment
How long does the Halo Effect discoloration last?
The Halo Effect appears only on the cotyledons and will remain there until they fall off. Unifoliates and trifoliates of the young soybean plant will emerge normal in color and growth. Since SDS and nematode symptoms are rarely seen in seedlings, the Halo Effect provides growers with the confidence that ILEVO seed treatmentis defending the plant.
Is there an effect on seedling emergence, plant stands or yield?
The Halo Effect has no detrimental impact on the speed of emergence, plant stands or yield. After three years of field testing, soybeans treated with ILEVO seed treatment emerge at the same speed as untreated beans. The presence of ILEVO seed treatment does not impact emergence or plant stands. In fact, field trials showed plants treated with ILEVO seed treatment produced a yield increase of 2 – 10 bushels per acre compared to fungicide/insecticide seed treatment package.
Is there a growth response to ILEVO seed treatment?
In some instances, growers may initially see a slower growth response as the soybean plant begins to process or metabolize ILEVO seed treatment. The slower growth allows the developing plant time to build up its internal resistance to SDS, effectively jump-starting the plant’s defense response in a manner similar to the way the human body reacts to vaccines. However, 20 to 30 days after emergence, growers will begin to see a healthier-looking plant, compared to untreated soybeans, because of the effective protection against SDS and nematodes.
Does ILEVO seed treatment trigger a response to herbicides?
A two-year study in Indiana and Iowa** found no interaction between the ILEVO seed treatment Halo Effect and preemergence herbicides. ILEVO seed treatment did not increase the potential for seedling damage from herbicides, and preemergence herbicides did not make ILEVO seed treatment less effective. The study found no negative effect on plant stand and soybean yield as a result of the Halo Effect or preemergence herbicides.
How does ILEVO seed treatment impact root rot and nematodes?
SDS is one of the most aggressive soybean root rot pathogens. Initial SDS infections occur on the roots and crowns of young soybean plants causing a phase that impacts the early-season health of the soybean seedling. Even when no SDS visual symptoms are experienced, root rot effects can still contribute to yield loss. ILEVO seed treatment controls this early-season root rot at the initial infection site before symptoms become visible, thereby reducing the incidence and severity of the impact SDS has later in the season. ILEVO seed treatment offers complete SDS protection as it protects against both the below-ground root rot and above-ground foliar symptoms of the disease.
Additionally, ILEVO seed treatment has a mode of action which provides broad-spectrum activity against nematodes including lance, reniform, root lesion, root-knot and Soybean Cyst Nematodes (SCN). SCN is the number one yield-robbing pest responsible for yield losses of more than 30% in some soybean fields.
