Pesticide Resistance Management
Lunch and Learn Series for fruit, vegetable and specialty crops
Presented by OMAFRA horticulture specialists: Hannah Fraser — Entomologist, Katie Goldenhar — Pathologist, Kristen Obeid — Weed Management
This series on pesticide resistance management is to give field growers with fruit, vegetable and specialty crops a holistic view on pesticide resistance. We will cover basics of pesticide resistance then dive deeper into insecticide, herbicide and fungicide resistance and management. Register with the link below, you will be able to attend all sessions. Sessions will start each day at 12 pm with a 30-minute presentation followed by question and answer period.
