Washington Pesticide Laws and Safety Practice Test

What involves the use of physical control methods in pest management?

1. The use of chemicals to disrupt the pest's lifecycle

2. Employing traps and barriers to physically remove or block pests

3. The manipulation of environmental conditions such as temperature or humidity to kill pests or alter their lifecycle

4. Rotating crops to prevent pest build-up

The correct answer is: The manipulation of environmental conditions such as temperature or humidity to kill pests or alter their lifecycle

The use of physical control methods in pest management refers to the physical manipulation or removal of pests from a specific area. This can include techniques such as trapping, fencing, or using barriers to physically block or remove pests from a particular space. Option A, the use of chemicals, would fall under chemical control methods rather than physical control methods. Option D, rotating crops, is a cultural control method that can help prevent pest build-up, but it does not involve physical control of the pests themselves. Option C, manipulating environmental conditions, is an example of biological control, where the use of natural predators or pathogens is used to control pest populations. Therefore, option C is the most appropriate answer as it directly involves the use of physical means to control pests.
