Manitoba crop insect and disease update

Conditions as of June 23, 2015

beetles on canola buds


Scout cereal crops for rusts, and consider whether fusarium is a risk. Insect feeding has been minimal in cereals, however watch for signs of feeding or larvae of cereal leaf beetle so we can assess levels of parasitism if these are present.

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.

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.
