Disease and insect update for Manitoba
By Top Crop Manager
June 24, 2015 - The Manitoba disease and insect update for this week notes that while insect feeding has been minimal in cereals, growers should watch for signs of feeding or larvae of cereal leaf beetle.
In canola, flea beetles are becoming less of an issue as canola advances beyond the susceptible stages and flea beetle populations decline.
In forage crops, alfalfa weevil continues to be at high levels in some alfalfa fields in the Interlake and Northwest areas of Manitoba
Cutworms are also becoming less of a concern as crops advance and cutworms begin to pupate. Grasshoppers are emerging and it is good to start assessing populations around field edges.
