WHAT’S NEW IN BLACKLEG MANAGEMENT?

Using the same disease resistance genetics over and over causes a shift in pathogen population, which can then overcome the resistance in our varieties – similar to herbicide resistance in weeds. Knowing the resistance genetics used in previous years will allow growers to rotate to a different resistance gene and reduce the blackleg infection within a field. As many as 10 new blackleg resistance labels will be applied to varieties in the coming years. They will use these letters A, B, C, D, E₁, E₂, F, G, H, X to identify major resistance genes present.

HOW EARLY IS TOO EARLY TO SEED?

Past experience would suggest that starting on peas and maybe some cereals in mid April would be the preferred early-seeding choice, with canola going in late April and early May. Growers may see value in experimenting with one early-seeded canola field, but other crops tend to be better options for seeding in mid April.

DON’T GROW DE-REGISTERED VARIETIES

Clearfield variety 46A76 has been de-registered by its registering company. Registration will be cancelled as of August 1, 2017, which means 46A76 crops harvested after that date cannot be legally delivered into the grain system in Canada. For this reason, growers should not grow 46A76 this year.

WEEDS: PRE-SEED BURNDOWN SCENARIOS

With a late harvest in many fields last fall, growers may have missed the opportunity for fall weed control. That could mean higher levels of winter annuals and perennials this spring. The delayed harvest could also mean higher amounts of volunteer canola seeds. This could be a big year for volunteer canola.
