Which of the following would not be considered a natural pest control method?

Natural pest control methods leverage ecological processes to manage pest populations without synthetic chemicals. Cultivation, which involves practices like tilling, crop rotation, and soil management, is aimed at enhancing soil health and creating an environment less conducive to pests. While it does influence pest dynamics, it is primarily geared towards optimizing plant health and yields rather than directly controlling pests through natural means.

On the other hand, wind, rain, and sunshine are natural environmental factors that can indirectly influence pest populations. For instance, wind can disperse pests or beneficial predators, rain can affect pest survival or encourage natural enemies of pests, and sunshine is vital for plant health, which helps strengthen plants against pest damage. Each of these factors plays a more supportive role in the ecosystem compared to cultivation, which is an active intervention rather than a passive environmental influence. Therefore, cultivation stands out as the option that does not fit into the same category as the others in terms of "natural" pest control methods.
