Pulse growers – do your part to uphold Canada’s reputation and keep markets open for all by being aware of the market considerations for pulse crop protection products. Click here to learn which products have market considerations for pulses before proceeding with your pulse crop management plans.

More than 85% of Canada’s pulse production is exported to feed the world. Market access is important to the Canadian pulse industry, and growers play a key role in keeping the doors to export markets open. Pulse growers need to know that the use of certain crop protection products may restrict marketing options. Growers are encouraged to review all of the following information before proceeding with their pulse crop management plans. Guidelines for specific products are can be found below.

Ensure product residues remain at trace levels or levels well below accepted maximums by following the 4 Simple Tips found here.

The success of the Canadian pulse industry relies on the ability to export the pulses produced in Canada. The demands of the end user are becoming increasingly complex. The chart below outlines the regulatory impediments to market access that can arise from using certain crop protection products. In addition to meeting our customers’ science-based regulatory requirements, Canadian pulses must also meet the requirements of consumer acceptance. In addition to meeting government regulations on food safety which govern trade, buyers of Canadian pulses will reflect consumer acceptance of various production practices.

What Are The Crop Protection Products To Pay Attention To This Season?

For pulse crop production in Western Canada, products that may pose market risks include diquat (Reglone®), glyphosate (Roundup®), saflufenacil (Heat®), glufosinate (MPower® Good Harvest®), flumioxazin (Valtera), carfentrazone (Aim®, CleanStart®), and chlorpyrifos (Lorsban and other trade names).

What Are The Risks Of Using These Products?

Late-season applications of fungicides, insecticides, pre-harvest weed control products, or desiccants may result in residue levels found in the seed. Growers must take appropriate risk mitigation steps to ensure product residues remain below maximum residue limits (MRLs) set by regulatory agencies.

Important Information Regarding The Pre-harvest Application Of Glyphosate On All Pulse Crops

The pre-harvest application of glyphosate is important for three reasons:

  1. Glyphosate use in general and specifically pre-harvest use is under increased scrutiny by customers of the Canadian pulse industry.
  2. Pre-harvest glyphosate must only be applied to pulse crops when seed moisture content is below 30% to avoid residue levels greater than the maximum allowable limit.
  3. A growing number of markets are testing pulse imports for glyphosate residues.

In order to keep our export markets open, it is imperative to follow the application rate and timing as indicated on the label of glyphosate-based crop protection products. Glyphosate is registered for pre-harvest weed control. Glyphosate is not a desiccant nor is it a tool to speed up crop maturity or dry-down. Pre-harvest glyphosate must only be applied to pulses when seed moisture content is below 30% in the least mature plants in the field. When using glyphosate in a tank mix with other products such as saflufenacil (Heat), glyphosate and the tank mix partner must still be applied when seed moisture content is below 30% in the least mature plants in the field.

For dry beans and peas, MRLs have been established for all major export markets. For chickpeas, lentils, and faba beans, CODEX MRLs have not been established. If applied according to label rates and only early in the crop year (e.g. single application at 0-20% flowering,) there are no export marketing issues. For chickpeas, lentils, and faba beans, do not apply later than the 20% flowering stage.
