Preparing for Spring

Here's some information and links that grower may find helpful as they start to think towards Spring.....

Link here to open our downloadable Canola Insect Scouting Chart.  You can print it but it’s also designed as a hyperlinked pdf file.  Each insect name can be clicked and it will take you directly to the page within the new “Field Crop and Forage Pests and their Natural Enemies in Western Canada”.  That complete guide is available as a free download both for printing or as an enhanced digital version.

We also encourage people to bookmark or subscribe to the Prairie Pest Monitoring Network Blog (for Weekly Updates and to access Risk & Forecast Maps produced during the grower season).  That Blog is active during the growing season.

I also mention the Manitoba Cutworm Fact Sheet with the nominal cutworm thresholds which is located at: http://www.gov.mb.ca/agriculture/crops/insects/fad06s00.html

For Albertans, the Cutworm Reporting tool which also maps will be located in the Spring at: http://www1.agric.gov.ab.ca/$Department/deptdocs.nsf/all/prm13779

Also keep the Syngenta flea beetle scouting pdf on hand – it’s a great visual guide to help assess percent defoliation.

This Week at the Farm, (May 22, 2015)

Now is the time when flea beetle monitoring is very important to canola producers!  

Flea beetles are important to canola production because they are an economic pest typically emerging from overwintering in the spring which begins to feed on the cotyledons of the canola seedling. Their feeding activity results in characteristic shot-hole damage.  More recently, striped flea beetles have been observed to girdle seedlings which immediately kills the plant.

Flea beetles reproduce in the spring and lay eggs near the stem of cruciferous plants.  Larvae will feed upon the canola root system but it is the adult or beetle which causes economic damage so in-field monitoring and the application of an action threshold of >25% cotyledon leaf area consumed is critical.

We monitor flea beetles to ascertain when they move into canola fields, to obtain a general estimate of the population densities active in specific fields, and to examine proportions of striped, crucifer, and hops flea beetles along with the lesser-known species that can also occur in our fields.  Flea beetles are approximately 2-3 mm long and are usually black, brown, metallic blue or purple and may have yellow stripes on their elytra (i.e., hardened forewings). 

Since 2001, our lab has monitored the density and species diversity of flea beetles found in commercial canola fields.  Below are photos depicting how we collect flea beetles using yellow sticky trap cards, and what they look like when we process the trap cards by examining them under a stereomicroscope.

Flea beetle trap out in the field ready to be collected. The black spots on the card are flea beetles (each 2-3mm long).

One flea beetle (Phyllotreta Striolata) stuck to the trap viewed using our stereomicroscope.

Two flea beetles (Crepidodera spp.) stuck to the trap viewed using our stereomicroscope.

This Week at the Farm (May 8, 2015)

First Traps of the 2015 Season!  This week, the IPM Program at Beaverlodge was again busy in the field setting up and collecting our insect pest monitoring traps.  At this time of the year, Flea Beetle and Diamondback Moth monitoring is important.

In this photo, Kaitlin sets up the first Diamondback Moth and Flea Beetle traps of the 2015 season which will be monitored weekly near Beaverlodge AB. Yellow sticky card traps will reveal the species diversity and relative numbers of flea beetles in canola fields whereas Diamondback Moth pheromone traps will detect the initial arrival of moths to canola fields.

This Week At the Farm (May 7, 2015)

Ever wondered about our equipment?  Here at the Farm, field plot equipment allows our researchers to replicate and that produces scientifically valid results.  The weather hasn't cooperated this week but the seeders are poised, ready to go....

ConservaPak and CrossSlot seeders preparing for #Plant15 here at the Farm.

And our sprayers are being prepared for pre-seed and in-crop pesticide applications that are part of the typical field crop production systems across the prairies.

New Staff at Beaverlodge

This week we welcome Jeremy Hodges to the Beaverlodge Research Farm!  Jeremy's training and experience will help support the Agronomy & Crop Adaptation Program based here at Beaverlodge.  He arrives in time to help with the organization of field plots areas, the sorting of seed  - everything that's critical to the vital process of seeding our field research plots where we continue to generate yield and quality data whether it's to study agronomic improvements or to continue to support the breeding of varieties well-suited to the northern production regions of Canada's prairies.

Spring 2015

The Beaverlodge Research Farm welcomes our student assistants to their summer positions.  The IPM Program is fortunate to have four returning students.  Watch for Shelby, Jadin, Amanda and Kaitlin doing insect pest monitoring again in 2015.
