Questions About Pesticide Resistance? OMAFRA Lunch and Learn Series has Answers.

Spider mite - Wikipedia

Pesticide resistance is something most growers have run into at some time or another. High pesticide resistance in species like western flower thrips and Bemisia whitefly is something we’ve learned to work around. But how can we avoid resistance in pest species where we still rely on pesticides? For pests like spider mites and powdery mildew, this is an ongoing battle.

Three OMAFRA specialists are hosting a series on pesticide resistance that will include question and answer periods after each session. Contributors are Hannah Fraser (Entomologist), Dr. Katie Goldenhar (Plant Pathologist) and Kristen Obeid (Weed Management). Read on for dates and how to register.

Lunch and Learn Series on Pesticide Resistance:

This series on pesticide resistance management is to give growers 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 12pm with a 30-minute presentation followed by question and answer period.

.Resistance 101 – Monday January 25th 12-1pm

  • Impact of resistance
  • How resistance occurs
  • Resistance drivers
  • Mechanisms of resistance
  • Challenges to management  
  • Foundations of resistance management
  • Resources for success

Insecticide Resistance – Tuesday January 26th 12-1pm

  • 16,000 cases and counting
  • Mechanisms of pesticide resistance in insects and mites
  • Risk factors beyond your control
  • How agronomic practices can drive selection pressure
  • Spraying by the numbers: IRAC MOA groups and your IPM program

Herbicide Resistance – Wednesday January 27th 12-1pm

  • Mechanisms of Herbicide Resistance
  • Herbicide Risk (WSSA groups, low vs high risk products)
  • Weed Risk – Current resistant weed situation: Focus on Amaranthus spp.
  • Agronomic Risk (practices that increase herbicide resistance risk)
  • Herbicide Resistance Management

Fungicide Resistance – Thursday January 28th 12-1pm

  • Fungicide Risk (FRAC groups, multi-site vs single-site, low vs high risk products)
  • Diseases at Risk (diseases at high risk, factors that increase resistance)
  • Agronomic practices that can decrease resistance risk
  • Fungicide resistance management (BMPs when using fungicides)

  1. Thank you for guiding pesticide resistance. Pest becomes immune to those pesticides which were used to eliminate them before. Integrated pest management provides a method that helps to minimize resistance. It will be great to take some information from you about this. Thank you very much. Please keep providing new information.
