Which of the following is an example of a treatment method in the context of pest control?

Heat treatment is an effective pest control method that involves applying high temperatures to materials, such as soil, plants, or wood, to eliminate pests and their life stages. This physical method of pest management is particularly important in phytosanitary practices, as it can reduce or eradicate pest populations without the use of chemicals, thereby minimizing the risk of residues and environmental harm.

For instance, in the treatment of wood products, heat treatment involves exposing the wood to a specific temperature for a designated time to kill any insect pests, larvae, and pathogens present in the material. This process is often used to secure compliance with international trade regulations that prevent the spread of invasive species.

Other options listed, while they have important roles in agricultural management and sustainability, do not specifically qualify as treatment methods for pest control. Soil enrichment enhances soil quality and fertility but does not directly target pest populations. Crop rotation is a cultural practice used to disrupt pest life cycles but does not involve a specific method to treat or eliminate pests. Organic farming encompasses a broader agricultural philosophy that emphasizes natural methods, but it does not itself define a specific treatment technique.
