For pulse growers, the locusts are both a major challenge and a potential threat. After a hot, dry year across the Prairie region last year, growers are concerned about what this growing season will bring for consumers of this resilient crop.
Farmers and agronomists are hoping a cool, wet spring will protect this season’s pulse crops from locust damage, but Dr. James Tansey with the Saskatchewan Ministry of Agriculture says in the report that it won’t be that simple. Pulse School. The weather has delayed hatching this year, but last year a large number of eggs were found underground, which has led to an increase in the population of harmful larvae.
Because there are only four major pest species of grasshoppers in Saskatchewan out of 85, and certain species can be present in large numbers on non-host crops without risking significant damage, it is important to know their habits and preferences to be more aware of what to look for on your crops.
Seedling and early pod-forming plants are particularly susceptible to grasshopper feeding, so Tansey recommends early scouting and ongoing monitoring of populations. Once damage begins to accumulate (which can happen quickly), it’s time for growers to take action.
