ILeVO

Overview

You may not even realize you have it. Soybean Cyst Nematodes (SCN) cause root damage and make soybeans more vulnerable to diseases such as Sudden Death Syndrome (SDS). So when you think of your soybeans and higher yields, think ILeVO seed treatment; the only seed treatment that protects against both SCN and SDS.

Protecting against these pests will help you maximize yield through ensuring a healthy start for your soybeans. The effectiveness of ILeVO is backed by field trials in the US and Canada over the past 6 years, including trials with the University of Guelph and the Ontario Ministry of Agriculture, Food and Rural Affairs.

2015 and 2016 Ontario field trials showed an overall ILeVO yield benefit of 3.6 bu/acre over the base treatment in areas with known nematode pressure.

2011 - 2016 US and Canadian university field trials showed an overall ILeVO yield benefit of 4.7 bu/acre in 338 variety locations in fields with and without above ground visual SDS symptoms observed.

  • 2015 US average yields were 2.9 bu/acre higher when soybeans were treated with ILeVO without above ground visual SDS symptoms observed
  • 2015 US average yields were 6.5 bu/acre higher when soybeans were treated with ILeVO with above ground visual SDS symptoms observed

The Halo Effect

You can see when ILeVO is working. The “Halo Effect” manifests itself as a short-term photo-sensitive reaction at the margin of the cotyledons, with almost no impact on true leaves, emergence, plant stands or yields. You can use it with the confidence that an application will positively impact your soybeans.

Under slow growing conditions ILeVO treated seeds may show delayed growth during VE to V2 growth stages. Plants transition quickly to normal plant characteristics as trifoliates appear.

Sudden Death Syndrome

ILeVO is the first and only seed treatment registered with activity on Sudden Death Syndrome (SDS) available to Canadian soybean growers:

  • ILeVO protects the root system against the SDS-causing fungus (Fusarium virguliforme)

SDS can cause significant financial and yield impact:

  • SDS damage results in average yield loss of 20%. It can result in yield loss of up to 60%
  • Difficult to identify and often misdiagnosed
  • SDS has spread into Southwestern Ontario and continues to move across Ontario, and its spread is closely related to Soybean Cyst Nematode distribution

Soybean Cyst Nematode

Soybean cyst nematode (SCN) presence is difficult to see and diagnose:

  • Soybean yields can be reduced up to 30% with visual symptoms
  • ILeVO protects the seed and roots in the seed zone, making it a valuable compliment to genetic resistance

Rates
CROP PEST RATES WATER VOLUME

17.5 - 35 mL / 140,000 soybean seeds
Note: The higher rate should be used on soybean seed planted in fields with high nematode pressure or in fields with nematodes as well as SDS. Fields with history of SCN should be planted with SCN-tolerant soybean cultivars in addition to ILeVO to achieve the best yield potential of soybeans.

Crop Restrictions
  • Do not replant to alfalfa for 14 days after application.
  • If the treated soybean crop is lost due to environmental conditions and re-seeding is required, all other crops may be replanted immediately.

Resistance Management

For resistance management, ILeVO contains a Group 7 fungicide. Any fungal population may contain individuals naturally resistant to ILeVO and other Group 7 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.

To delay fungicide resistance:

  • Where possible, rotate the use of ILeVO or other Group 7 fungicides with different groups that control the same pathogens in a field.
  • Use tank mixtures with fungicides from a different group that is effective on the target pathogen when such use is permitted.
  • Fungicide use should be based on an integrated disease management program that includes scouting, historical information related to pesticide use and crop rotation and considers host plant resistance, impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other chemical control practices.
  • Monitor treated fungal populations for resistance development. Notify Bayer if reduced sensitivity of the pathogen to ILeVO is suspected.
  • If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide with a different target site of action, if available.
  • Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for specific crops and disease problems in your area.
