Canola Scouting Guide

Field scouting is critical because it enables the identification of potential risks to crops. Canola production systems across the Canadian prairies will suffer insect pest outbreaks. However, the identification of these insect pests PLUS the application of established monitoring methods will enable growers to make informed pest management decisions.

This year we offer a generalized canola scouting chart to aid in-field scouting on the Canadian prairies. This guide contains hyperlinks to help growers learn more about some of our insect pests and how to monitor.

Whenever possible, monitor and compare to established economic thresholds so pollinators and beneficial arthropods are preserved.  Economic thresholds, by definition, can help growers avoid crop losses due to an insect pest.

Good luck with the growing season!

June is Cutworm month!

We have ~143 cutworms and the majority came from the Guy/Falher area between Jun 3-5, 2015.  About 65% of the material we are shipping to AAFC-Saskatoon where we’ve requested they try to include them in future multiplex PCR or CO1 barcoding to identify the species x  host crop associations. 

Anyone seeding an annual into 2014 legume stubble should be carefully scouting for cutworms if they’re anywhere East of Wanham.  The absence of precipitation but warm temperatures mean that cutworm damage is showing up quite suddenly where other years moisture helps the plants grow quickly and tolerate cutworm feeding

Please report Albertan cutworm sites! 

Every entry is important because it helps us all estimate how much of a problem we have now and into 2016.  Once data entry occurs, your growers can be checking the live cutworm map located here.

2015 Prairie Pest Monitoring Network's Weekly Updates

The Weekly Updates for the 2015 growing season are now being compiled.  Each week, growing conditions, pest updates and scouting tips are summarized into a single place to enable in-field scouting of our economically important field crop pests.  Access the Weekly Updates by linking here or view them on the Prairie Pest Monitoring Blog.

This Week at the Farm (June 3, 2015)

Grasshopper scouting is starting in the Peace region. Most grasshoppers overwinter as eggs laid in the soil and emerge in the spring as tiny nymphs. This week, we're seeing small nymphs measuring ~4mm long that will quickly grow as they feed.

While our lab doesn't have grasshopper research projects underway, we do keep an eye on their numbers both in our field plots plus we collect from our region to verify predictive models developed by Dr. Owen Olfert's lab based at AAFC-Saskatoon. For example, while scouting new monitoring sites near Guy AB, we collected some very early instar grasshopper nymphs that will be sent to Saskatoon.

Correct identification of grasshoppers is critical to making management decisions and growers need to understand there are several species of grasshoppers in our region that do NOT cause economic damage. Species that can cause economic levels of damage include: the migratory grasshopper (Melanoplus sanguipes), two striped grasshopper (Melanoplus bivittatus), Packard's grasshopper (Melanoplus packardii), and the clearwing grasshopper (Camnula pellucida).  All four species will feed on weeds as well as field crop plants.  Migratory, clearwing and Packard's grasshoppers will feed on both broadleaf and grassy plants.

In-crop field management

Every grower likes to look at machinery and our technicians are no different!  The Agronomy Program was able to acquire this new high-clearance sprayer to support ongoing and new research here at the Farm.  The booms fold and are retractable to allow for applications to variable widths of research plots but it's also more efficient in how it uses water and in the accuracy of application of the various pesticides that are part of normal field crop production here on the prairies.  Equipment like this is moving our field research forward.

This Week at the Farm (June 1, 2015)

Hi, my name is Andras and I'm the final summer Co-op student, from UBC, to arrive at the IPM Program here at Beaverlodge.  I got off to a bit of a late start and had catching up to do given all the studies the IPM program runs.

The first study I worked on was the Red Clover Casebearer Parasitoid Rearing study. The purpose of this study is to build our knowledge of the species that are parasitoids of the red clover casebearer moth. We check the collected casebearer pupae daily for emerged parasitoids, moths, and diseased larvae, and emerged moths or wasps are promptly recorded and the specimens preserved for future analysis.  A preserved parasitoid wasp can be seen in the image below:  



The next assignment was the IPM program's contribution to the Prairie Pest Monitoring Network.  Traps specifically targeting flea beetles and diamondback moths were set up at sites in the region to acquire data on insect pest population levels.  By collecting the traps weekly, and immediately analyzing them for the species of interest, changes in the insect populations are closely monitored and that information is used to support growers' pest management strategies.

But in the coming weeks, even more studies will pick up again for the summer; just to name a few:

• Lygus Caging Study - determining whether established economic thresholds for Lygus are applicable on newer hybrid canola varieties
• Annual Canola Surveys - early-mid flowering stage sweep-net surveys to obtain information on regional insect biodiversity, population levels of all pests, and to monitor for cabbage seedpod weevil range expansion from the south
• Lygus Parasitoid Study - obtaining a better understanding of the insect species that parasitize nymph and adult Lygus bugs, the parasitoid species diversity, and the rate of parasitization

It is not surprising that there is so much to learn given the scope of the IPM program's studies, but the other co-op students and staff have been very helpful and supportive in my first week so far. We're going to do some great work this summer.
