Some areas of the prairies have received some rain over the past few days, but the weeks of hot, dry weather have had an impact on crops, hay, and pastureland.
With the dry conditions across so much of the Prairies, there's been an increased concern about grasshopper infestations.
Dr. Meghan Vankosky, a research scientist in field crop entomology with Agriculture and Agri-Food Canada, says grasshoppers could be shaping up to be an important story again this year.
Last year, while grasshopper infestations were not as severe as anticipated, certain areas still experienced high adult densities in the fall. The favourable fall conditions allowed grasshoppers to lay eggs extensively, setting the stage for potential problems this spring.
She noted that the grasshopper hatch has begun, albeit somewhat patchy. "It's important to be scouting," she emphasized. Dr. James Tansy from the Saskatchewan Ministry of Agriculture reported that grasshopper nymphs are currently concentrated on roadsides and ditches, rather than in fields. Producers are advised to scout field edges to anticipate potential infestations, especially with warmer weather on the horizon.
In addition to grasshoppers, flea beetles remain a concern. "Around Saskatoon and in parts of Alberta and Manitoba, flea beetles have been damaging crops," Dr. Vankosky said. Experimental research plots at Saskatoon have required treatment to protect plants for variety trials.
Another pest to watch out for is the diamondback moth. Dr. Vankosky mentioned that pheromone traps are in place to monitor diamondback moth populations. "Some traps in Manitoba have recorded more than 250 moths," she said, indicating a potential risk. In Alberta, certain areas have also reported high moth densities. The short generation time of diamondback moths means multiple generations can occur over a few months, increasing the risk to crops.
Dr. Vankosky also highlighted the importance of monitoring pea leaf weevil and wheat midge populations. "The pea leaf weevil annual survey is wrapping up, and reports indicate higher than expected numbers in all three Prairie provinces," she said. While farmers may not be able to address this issue immediately, it is crucial to plan ahead for next year's crops.
She says that they are also monitoring for potential wheat midge development, something producers should watch for if we see some timely rains.
Overall, Dr. Vankosky says it's important that farmers scout and monitor crops on a regular basis to stay ahead of potential problems.
