Resources to grow market-ready crops

Certain crop protection products can restrict the marketing options for your pulse crop. Before you make your crop management plans, talk to your grain buyer and read the Keep it Clean Pulse MRL Advisory for a list of products of concern for 2020, and the steps you can take to mitigate risk.

Pulse growers – do your part to uphold Canada’s reputation and keep the doors open to key markets by being aware of the market considerations for pulse crop protection products. Before proceeding with your crop management plans, read the Keep it Clean Pulse MRL Advisory below to learn which products can restrict the marketing options of your pulse crop.

More than 85% of Canada’s pulse production is exported to feed the world. Market access is important to the Canadian pulse industry, and both growers and their advisors play a key role in keeping the doors to export markets open. By knowing the market impact of crop protection product choices and taking steps to mitigate risk, we can ensure Canada’s pulses continue to meet the needs of our domestic and export customers.


The success of the Canadian pulse industry relies on the ability to export the pulses produced in Canada; however, the demands of the end user are becoming increasingly complex. In addition to meeting the science-based regulatory requirements of our domestic and export markets, Canadian pulses must also meet the requirements of consumers and their acceptance of various production practices. The information below outlines the regulatory impediments and challenges to market access that can arise from using certain crop protection products.

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

For pulse crop production in Canada, active ingredients that may pose market risks include glyphosate (e.g. Roundup®), diquat (e.g. Reglone®) and glufosinate (e.g. MPower® Good Harvest® in Western Canada and Ignite® in Eastern Canada.)

What Are The Risks Of Using These Products?

Late-season applications of pre-harvest weed control products and/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. Only apply pesticides that are both registered for use on your crop in Canada and won't create trade concerns, and always read and follow the label for proper application rate, timing and pre-harvest interval (PHI).

Important Information Regarding The Pre-Harvest Application Of Glyphosate

Glyphosate is under increased scrutiny in the global marketplace and some pulse crops have low MRLs in major export markets. Some grain buyers may not accept pulse crops treated with pre-harvest glyphosate. Check with your grain buyer before use.

Glyphosate is registered for pre-harvest weed control and is not to be used as a desiccant. Pre-harvest glyphosate must only be applied when grain moisture content is less than 30% in the least mature part of the field to prevent unacceptable residues in the harvested grain.

When using pre-harvest glyphosate in a tank mix with other products, such as Saflufenacil (e.g. Heat), glyphosate and the tank mix partner must still be applied when grain moisture content is less than 30% in the least mature part of the field. Users must adhere to the PHI of the most restrictive product label.

To keep our export markets open, it is imperative to follow the application rate, timing and PHI as indicated on the label of glyphosate products. Additional information, including proper application timing and pulse crop staging guides, can be found at Fall Application of Glyphosate.
