Lowering the humidity of stored grains to reduce mold damage is an example of which pest management method?

Lowering the humidity of stored grains to reduce mold damage is an example of physical/environmental modification because it involves altering the environmental conditions to manage pests and prevent mold growth. This strategy effectively reduces the moisture levels that create a conducive environment for mold and other pests to thrive. By maintaining lower humidity, it is possible to decrease the likelihood of mold development and overall spoilage of the grains.

Physical/environmental modification encompasses practices that change the physical environment to make it less favorable for pests. This can include temperature control, humidity regulation, and even changes in light exposure. In this case, manipulating the humidity specifically targets the environmental factors that support mold proliferation, illustrating a proactive approach to pest management through environmental control rather than chemical or mechanical means.
