What does Microbial Decomposition refer to in the context of pest management?

• A. Microbial Decomposition
• B. Biological Control
• C. Mechanical Control
• D. Chemical Decomposition

Answer: (A)

Microbial decomposition refers to the breakdown of organic material by microorganisms such as bacteria and fungi. In pest management, this process helps by reducing the amount of crop residues, manure, and other debris that can harbor pests or provide overwintering sites. As microbes break down this material, they also recycle nutrients and improve soil health, which can strengthen plants against pest pressures. This focus on how microbes break down matter is why it fits best as the described concept: it centers on microbial action itself rather than directly killing pests, as biological control does, or on physical removal (mechanical control) or on pesticides (not a decomposition term).
