Definition of IPM and a discussion on the principles of IPM: Pest identification; Monitoring; Threshold levels; Control measures and Evaluation. An example will be used to illustrate the principles.

This module will provide an overview of IPM, discuss the botanical characteristics of these 3 weeds, their method of spread, their economic impact and the application of IPM techniques and strategies to control these 3 noxious weeds in agricultural, industrial and urban environments.

Most things we do each day pose a risk to us, whether that is driving your vehicle to work or applying a pesticide. The public tends to focus on the risks of pesticides and not the benefits. Join Tim as he looks at the huge benefits that we receive by using pesticides in our world. You will be surprised when you see all the primary and secondary benefits of the pesticide industry. It is time to look at and promote the benefits of pesticide in the modern world.

This webinar looks at the current status of biological weed control agents in Canada. Biological control has had some success over the years but with increasing pressure on chemical pesticide use, it is important to keep updated on what is happening with biological control agents. Join Tim as he reviews the current status of biological weed control agents and what the future looks like.

As more pressure is put on pesticide usage, applicators must look to an IPM program when dealing with unwanted vegetation. We may need to divide areas into different categories as far as what is acceptable and not acceptable. We need to be able to count or measure plant populations in order to decide the solution required. Monitoring of vegetation will be discussed. Thresholds will be defined and discussed. A look at various control measures will be examined included guidelines for selecting appropriate herbicides.

Plants and animals are completely different-or are they that different. Just because plants cannot run away, fight or scream, it does not mean they cannot defend themselves. They can communicate with each other or others such as pollinators or even predators of their enemies. Plants interact with each other and have defense systems. Join Tim as he looks at the world of plants and how we may be able to use their defense systems in IPM programs now and in the future.

Pesticide resistance is increasing throughout the world. What can we do as applicators to prevent this or slow it down. The scope of resistance is discussed as well as definitions. The different types of resistance are discussed and applicators will realize they have a high level of control on some types of resistance and lower levels of control on others. Ways applicators can reduce pesticide resistance is presented.
