EC cannot help make VR strategies more consistent

Science Edition 2016—Key Result: While soil electrical conductivity (EC) measurement is a strong indicator of soil clay and moisture content, it cannot help to make variable rate (VR) fertilizer programs more consistent. Producers using VR should be prepared to use a specific strategy for each field each year. Project title, Principal investigators: “Understanding soil variability for effective...

Identifying and controlling cutworms

During cutworm outbreaks, accurate and rapid identification is required to maximize control methods.

Science Edition 2016—Key result: A pest complex of economically significant cutworm species can be found on the Prairies, and outbreaks seem to be occurring with greater frequency. This study has resulted in a DNA protocol for quick, accurate identification of cutworm species; identification of natural enemies and evaluation of their ability to develop on different cutworm species;...

Storage bags work best with dry canola

Science Edition 2016—Key result: This research looked at the feasibility of bag storage for canola and the effects on seed quality based on moisture content and length of storage time. Dry canola seeds can be safely stored for six to eight months in bags, but canola at 12 per cent moisture should be stored only temporarily. Project...

The fate of sulphur fertilizers in the soil

Science Edition 2016—Key Result: Choosing the most suitable sulphur (S) fertilizer for the conditions can be difficult. This study found that soluble sulphates, thiosulphate and gypsum are effective at providing early supplies of plant-available sulphate in the seed row. An early supply of sulphate appears to be important for plant S uptake and yield. Project title, Principal...

Herbicides that could improve cleavers control

Cleavers species are difficult to control and can cause downgrading and reduce crop quality.

Science Edition 2016—

It is important to note that, as of October 2016, clomazone is not yet registered and quinclorac should not be used on canola due to maximum residue limit (MRL) issues. Until exporters and processors are confident that they can ship quinclorac-treated canola without trade concerns, growers are advised to avoid this marketing risk by using other cleavers control methods.
