Lowering the humidity of stored grains and other food products to reduce damage from mold is an example of which type of pest management method?

Lowering the humidity of stored grains and other food products is a classic example of physical/environmental modification in pest management. This method involves changing environmental factors to make conditions less favorable for the pests, which in this case are mold and other organisms that thrive in high humidity.

By reducing the humidity, the growth of mold is inhibited, effectively managing the problem without the use of chemical pesticides. This proactive approach not only helps in preserving the quality of stored food products but also minimizes the reliance on additional pest control measures that might have unwanted side effects.

Mechanical methods typically involve physical barriers or traps, while biological methods focus on using natural predators or pathogens to control pest populations. Regulatory pest control generally involves laws and regulations to manage pest issues, which is not applicable in this context.
