How to manage without lambda-cyhalothrin in 2023

Alternatives to control most insect pests exist but attention to label recommendations, product rates and timing is important

As of mid-February, if western Canadian farmers want to control common crop insect pests such as grasshoppers and flea beetles in 2023, they should plan to do it without the use of popular lambda-cyhalothrin products such as Matador and Silencer. Those products and others based on the lambda-cy active ingredient aren’t banned, but Health Canada’s […] Read more

Lygus bugs tend to prefer warmer temperatures and can be significantly affected by fungal pathogens under high relative humidity.

Weather affects pest and predator populations

Insect management, temperature and rainfall

All insects can be influenced by weather conditions during the growing season. When pests and their predators respond to weather changes in a similar way, natural enemies can be effective at controlling pest populations. Unfortunately for farmers, that’s not always the case. Meghan Vankosky, a research scientist in field crop entomology at Agriculture and Agri-Food […] Read more
