Entomologist Recommends Proactive Approach to Neonics on the Prairies

Regulatory restrictions are not on the radar in Manitoba, but the province’s agriculture entomologist suggests farmers in Western Canada should ask themselves “why?” before using neonicotinoid seed treatments.

Corn School: Scouting for Three Early Season Pests — Wireworm, Cutworm & Grubs

Skipped plants in a corn row aren’t always due to mechanical error or seedling blights. Early insects like wireworm or grubs can kill plants rather stealthily, leaving gaps in a row or neat leaf damage, while cutworm can clip off a patch of plants overnight. Knowing which insect causes what damage is important when assessing… Read more »

The longer answer, however, is that tram lines may make scouting for insects easier and more thorough, and thus beneficial. Not convinced? Read on. Some insects are predictably found on the edge of the field — like flea beetles,… Read more »

Monitor Populations & Soil Temp to Gauge Wireworm Risk

Wireworms have been on the rise in many areas of the prairies, due in part to the banning effective insecticides, such as Lindane, years ago. Unlike several other pests, wireworms have a very long lifecycle —spending three to five years as seed-eating worms. There are about 30 species of the pest that are of economic… Read more »
