Agriculture Roundup for Thursday, July 2

Canola crops can suffer from nutrient deficiencies.

Lyle Cowall is a manager of agronomy services with Nutrien Ag Solutions in northeast Saskatchewan.

He said a lot can be learned about phosphorous deficiency be having a test done.

“Tissue testing can be very valuable and it can be misleading, and one of the best ways to use tissue testing in trying to diagnose a deficiency is to use a comparative tissue test. Sample the good, and compare that to the bad plants,” Cowall said.

He said you will learn far more from a comparative test than you will from an individual tissue test.

Cowall recommends a comparative tissue test if you are looking for more answers.

Prevention is the key to herbicide resistant weed control.

But if you already have a problem on your farm, Dr. Charles Geddes with Agriculture Canada based in Lethbridge says knowing what the problem is will help you find a proper control program.

“Resistance across the prairies appears to be increasing based on our surveys,” Geddes said.

He said it’s important to test weeds for resistance, as it will inform herbicide decisions down the road. Geddes added you should also try to mitigate resistance in the first place.

Management is possible, but is more expensive, according to Geddes.

Registration is now open for the Ag In Motion digital event.

July 21 to 25, farmers can have access to new equipment, livestock experts, exhibitor innovations and more on Ag in Motion Discovery Plus.

This virtual event will bring a farm show experience on-demand and free of charge.

Equipment will be featured in side-by-side videos allowing farmers to compare products, there will be a virtual Ride & Drive, and livestock central will demonstrate cattle handling and livestock equipment.

Crop plot tours will look at time-lapse photography and interviews with representatives to discuss what is new for 2020.
