Grasshoppers

There are many types of grasshoppers in Alberta, but the three main ones of concern in the County are:

Migratory;
Two-Stripe;
Clear-Winged (to a lesser degree).

These pests can become a serious issue when drier and warmer summers, combined with milder winters, lead to an increase in populations.

Prevention

Grasshoppers have become a major concern in many areas in the County. Although they are difficult, and sometimes very costly to control, there are a few strategies that may decrease their impact on crops:

Practice an Integrated Pest Management approach which will encourage the development of natural predators of grasshoppers;
Plant crops earlier, if possible, to avoid damage at most susceptible times;
Use buffer strips of less attractive crops (Oats and Peas) around the edge of fields that are more likely to have an infestation;
Mow headlands to reduce suitable grasshopper habitat;
Apply an early application of insecticidal bait to control early stage grasshoppers as they enter the field, the County has a truck mount applicator available for rent to apply the insecticidal bait;
Scout fields regular to detect early stage grasshopper movement; and
Apply a registered insecticide at recommended rates early and around the outside borders of fields.
