Prairie Pest Update #16

Lygus bugs, pre-harvest intervals, and more

Weather synopsis – Below is the Accumulated Precipitation for the Growing Season

Insect Development and Simulation Outputs – Model outputs are now completed for the 2014 growing season. Thank you to the dedicated AAFC-Saskatoon Staff who compiled data, generated and mapped the output data, plus provided weekly summaries for the various insect pest species during the 2014 season!

Lygus Bugs (L. lineolaris, L. keltoni, L. borealis, L. elisus) – Remember, hot dry weather favors the buildup of lygus bug populations. The economic threshold for lygus bugs in canola is applied at late flower and early pod stages. Biological and monitoring information related to lygus bugs can be accessed by clicking here or you can access Manitoba, Alberta or British Columbia fact sheets.

No-Till vs Tillage: Why Neighboring Fields Are World Apart

Video: No-Till vs Tillage: Why Neighboring Fields Are World Apart

“No-till means no yield.”

“No-till soils get too hard.”

But here’s the real story — straight from two fields, same soil, same region, totally different outcomes.

Ray Archuleta of Kiss the Ground and Common Ground Film lays it out simply:

Tillage is intrusive.

No-till can compact — but only when it’s missing living roots.

Cover crops are the difference-maker.

In one field:

No-till + covers ? dark soil, aggregates, biology, higher organic matter, fewer weeds.

In the other:

Heavy tillage + no covers ? starving soil, low diversity, more weeds, fragile structure.

The truth about compaction?

Living plants fix it.

Living roots leak carbon, build aggregates, feed microbes, and rebuild structure — something steel never can.
