Entomologist John Gavloski is warning producers to maintain beneficial bugs found in crops

Predatory and parasitic insects can contribute to pest suppression for your crops

By
Pest control services provided by naturally occurring, beneficial insects save growers in the United States around US$4.5 billion per year. Add that to the just over US$3-million benefit they provide through pollination of crops, and these are pretty valuable critters to have on the farm.

Canola under pressure from cutworms, flea beetles

Manitoba Insect & Disease Update summary for June 1

By
Insects Cutworms and flea beetles on canola continue to be the insects of greatest concern. The cool, damp weather from the last few days would have slowed cutworm feeding, and the soil moisture, where not excessive, may help the plants compensate for feeding. Cutworm levels are quite variable, hard to find in some fields, more
