Which of the following is a method of pest control mentioned as an alternative to pesticides?

Polyculture is a method of pest control that involves growing multiple types of crops in the same space, which enhances biodiversity. This approach can help manage pest populations naturally by creating an environment that is less conducive to pest outbreaks. Diverse plant species can attract beneficial insects that prey on pests or deter pests through competition or natural plant defenses.

In contrast, single crop farming tends to create monocultures, which can lead to increased susceptibility to pests because a large area of identical plants can be easily targeted by pests. The use of synthetic fertilizers is focused on enhancing crop growth and nutrient availability, rather than directly addressing pest issues. Ineffective traps may not provide reliable or sustainable solutions for pest control, as they do not significantly reduce pest populations or improve yields effectively. Hence, polyculture stands out as a viable alternative method that not only addresses pest management but also promotes overall ecosystem health.
