Which of the following is NOT a primary method of pest management for agricultural crops?

Cultural control, biological control, and chemical control are all established methods used in integrated pest management to mitigate pests affecting agricultural crops.

Cultural control involves practices that modify the environment and agricultural practices to deter pests, such as crop rotation, planting resistant varieties, and proper sanitation. This method aims to create conditions that are less favorable for pest establishment and proliferation.

Biological control is the use of natural enemies or organisms to control pest populations. This includes employing predators, parasitoids, or pathogens to manage pest numbers naturally and sustainably.

Chemical control employs pesticides to eliminate or manage pest populations. The strategic use of these substances can help protect crops from harmful pest infestations.

In contrast, medical control is not recognized as a primary pest management strategy for agricultural crops. It is typically associated with human health and public health scenarios rather than crop management, making it an inappropriate choice in the context of agricultural pest control.
