What is a cultural control technique used in pest management?

Cultural control techniques in pest management involve altering the environment or cultural practices to make it less conducive to pest infestations or diseases. By promoting environmental changes that create conditions less favorable for pest growth, you can effectively reduce pest populations without relying on chemical interventions. This can include practices such as crop rotation, proper irrigation, soil management, and choosing resistant plant varieties, all of which contribute to a healthier ecosystem that can suppress pest issues naturally.

The other choices offered represent different pest management strategies that might not align with the principles of cultural control. Introducing natural predators is a form of biological control, while applying chemical pesticides and using fungicides are examples of chemical control methods. Each of those methods can be effective in certain situations but does not fall under the umbrella of cultural controls which focus on environmental management rather than external inputs.
