Utah Ornamental and Turf Pest Control Practice Test

The identified answer, high wind and extreme heat, represents a natural control method for pest management as it relies on environmental factors to manage pest populations. High wind can physically dislodge pests from plants or disrupt their ability to move and reproduce, while extreme heat can create inhospitable conditions for many pests, potentially reducing their numbers. This kind of natural control fits into the broader category of using the environment to influence pest populations without chemical intervention.

In contrast, pesticide application is clearly a chemical control method that utilizes manufactured substances to manage pests. Soil tillage and crop rotation, while beneficial practices in agriculture for various reasons—like improving soil health and disrupting pest life cycles—do not necessarily fall under the category of natural environmental controls in the same immediate sense that high wind and heat do. They involve human intervention and management, rather than relying solely on environmental conditions.
