The government of Ontario aims to reduce the number of acres planted with neonicotinoid-treated corn and soybean seed by 80 per cent by 2017. The intent is to ensure that neonicotinoid-treated corn and soybean seeds are used only when there is a demonstrated pest problem. To that end, new regulations on the sale and use of seed treated with neonicotinoids, or neonics, (now referred to as a Class 12 Pesticide) were introduced July 1, 2015, and are being phased in over time.

As your seed solutions provider, PROSeeds and its representatives are available to you for advice and support during the transition and throughout the phased implementation of these regulations.

Here’s a summary of what you need to know:

From August 31, 2015 to August 30, 2016:

  • Dealers who wish to sell or transfer corn or soybean seed treated with neonics need a new vendor’s license.
  • Growers are allowed to plant up to 50% of their acreage, by commodity, with neonic-treated seed.
  • To do so, growers must complete a Seed Amount Declaration stating that they are not buying or using more than what is required to plant 50% of this area.
  • Separate declarations are required for corn and for soybean.
  • A Seed Amount Declaration is valid only for seed intended to be planted in the 2016 growing season.
  • To plant more than 50% of land with neonic-treated soybean or corn, growers must conduct and submit a Pest Assessment Report demonstrating that there is a pest problem. During this initial period, any farmer can do soil pest scouting, perform a pest assessment and prepare a report.

From August 31, 2016 until August, 31, 2017:

  • If growers want to buy and use any amount of neonic-treated seeds, they will be required to:
    • Complete the new integrated pest management (IPM) training.
    • Complete a pest assessment report.
    • Sign a declaration called an IPM Written Declaration Form stating that they have considered IPM principles.
  • Farmers will be able to perform a pest assessment and prepare a report themselves if they have a certificate number from completion of the IPM training. This training is available free of charge (until September 2016) in various locations or online through the University of Guelph.
  • Growers can then plant treated seed only on acreage identified in their Pest Assessment Report. 

Starting on August 31, 2017:

  • A requirement that a professional pest advisor conduct a soil pest assessment and prepare a report will begin to be phased in over time on a geographic basis.

Exemptions include:

  • If you will not be planting neonic-treated corn or soybean seed, you will not be subject to any new requirements under this regulation.
  • The regulation does not apply to soybean seed planted for the purpose of producing a soybean seed crop of certified status under contract. Nor does it apply to popping corn, sweet corn or corn used for the production of seed.
  • Soybean seed and corn seed treated only with fungicide are not classified as Class 12 pesticides under the regulation, and can be planted without completing government paperwork.
