Question

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?

1) Biological control
2) Chemical control
3) Cultural control
4) Physical control

Answer 1

Lowering the humidity to prevent mold growth in stored grains is a physical control method, utilizing desiccation and environmental manipulation to inhibit microorganism growth without biological or chemical agents.

Step-by-step explanation:

Lowering the humidity of stored grains and other food products to reduce damage from mold is an example of physical control method of pest management. This method includes various techniques such as refrigeration, freezing, and desiccation to control the growth of pests by creating environmental conditions that are not favorable to them.

It is part of the broader practice of preserving food by inhibiting the growth of microorganisms without the use of biological agents such as other organisms, nor chemical agents like synthetic pesticides. Physical methods are often used in combination with other pest management strategies for more effective control.
