When spraying for weeds it may be economical to add an insecticide or fungicide to the tank mix to hit any insects or disease (blackleg) that may be present at the same time. However, consider these four issues before proceeding: 1. Is the tank mix supported by the product manufacturers? (See the next article for more on this.) 2. Be…

Cutworm activity has been light so far this year, with a few fields sprayed across the Prairies. We do expect to hear of more cases as crops start to emerge and feeding patches start to show up. Keep an eye out as many cutworm species will feed on canola, and each has its own cycle — as the table shows… -
There are no reliable solutions to crusting 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… -
Heavy rains in the past week left some Prairie canola fields under water. Canola is quite susceptible to water logging and shows a yield reduction after only 2-3 days with wet feet. Wet soils cause an oxygen deficiency, which reduces root respiration and growth. Root failure reduces nutrient uptake, and plants will eventually die unless drowned areas dry out quickly… -
Growers hoping to seed their final canola acres this week or next week may want to consider the following tips to deal with a shortened growing season… -
Two key questions arise after a spring frost: 1. Did the crop survive? (Do I need to reseed?) 2. When can I resume weed control? It takes some time answer these questions, which is why waiting a couple days is important. How to answer them…
