Gopher management. Richardson ground squirrels — often mistakenly called “gophers” — are flourishing in some locations. Gophers can eat up large areas within a canola field, and their damage is often mistakenly blamed on cutworms or other insects. Strychnine baits and, in some jurisdictions, mix-it-yourself strychnine liquid is available for gopher control. Talk to your municipal or county office for options in your area.

What to do about crusting? Rain after seeding can often cause top soil to crust, stopping the emergence of canola seedlings. There are no reliable solutions other than to wait for rain. Some growers have reseeded the worst sections of fields. A light harrowing might help if nothing has come through. Do a couple passes then assess whether canola seedlings are being ripped out of the ground. Harrowing too close to emergence can be harmful to a shallow seeded crop such as canola and may not be worth the risk. Using a roller may be worse than harrowing when soils are wet below the crust. Instead of cracking up the soil surface, a roller could turn the whole topsoil zone to concrete. Again, there is very little research on how to manage crusting. It’s trial and error. Read more.

Keep It Clean. Only apply pesticides that are registered for use on canola in Canada and won’t create trade concerns. Talk to your grain buyer to ensure that the pesticides you’re using are acceptable to your customers. Follow the correct rates and timing listed on the label. Read more.
