When Minor Pests Go Major: Ants, Chinch Bugs and Leatherjackets

Session Summary

This presentation will focus on the management of several sporadic or minor pests in turfgrass systems, including ants, chinch bugs, and leatherjackets, which have become increasingly problematic as effective control of major pests (e.g. white grubs) has become more difficult with the loss of key active ingredients in Canada. This shift in pest dynamics, has necessitated a renewed focus on these lesser-known but impactful insects. Attendees will learn about the biology and behavior of these pests, as well as the latest strategies and new products available for their management. The session will also explore how evolving pest pressures and the introduction of new insecticides and university research into alternatives are reshaping turfgrass pest control in Canada.

Learning Objectives:

1. Understand the biology and behavior of ants, chinch bugs, and leatherjackets and their impact on turfgrass systems in Canada.

2. Evaluate the latest management strategies and new products available for controlling these minor pests in the context of changing pest dynamics and regulatory restrictions.

3. Explore how university research and the development of alternative pest management approaches are shaping the future of turfgrass pest control in Canada.

Digging Deep: Effective Strategies for Managing Earthworms and White Grubs in Canadian Turfgrass

Session Summary

This presentation will delve into the challenges and solutions for managing two of the most persistent pests in Canadian turfgrass systems: earthworms and white grubs. While earthworms are beneficial organisms that enhance soil health and structure, their activity can disrupt turf surfaces with unsightly castings, while white grubs damage roots, leading to weakened and patchy grass. Attendees will gain insights into the biology and behavior of these pests, understand their impact on turf health, and explore practical, science-based management strategies. From integrated pest management (IPM) approaches to innovative tools and techniques, this session will equip turfgrass professionals with the knowledge to address these subterranean challenges effectively and sustainably.

Learning Objectives:

1. Identify the biological and ecological roles of earthworms and white grubs in turfgrass systems and their potential impact on turf health and playability.

2. Examine effective, science-based strategies for managing earthworms and white grubs, including integrated pest management (IPM) approaches tailored to Canadian turfgrass environments

3. Analyze how evolving pest pressures, new management tools, and recent research findings influence sustainable turfgrass management practices.
