Which of the following is a cultural control method?

Cultural control methods involve practices that enhance crop health and reduce pest pressure through changes in agricultural practices. Controlled burning is a technique that fits this category as it can help manage weeds, pests, and diseases in a specific area by using fire to remove unwanted plant material and pests from the landscape. This practice not only prepares the land for new growth but also promotes soil health by returning nutrients to the soil after materials are burned.

In contrast, biological control focuses on using natural predators or parasites to manage pest populations. Chemical control involves the application of pesticides to eliminate or regulate pest populations directly. Mechanical control includes physical methods of pest management, such as traps or barriers. Each of these methods serves a different purpose in pest management, but controlled burning stands out as a cultural control method due to its integrative approach to managing ecological balance within the farming system.
