________ degradation of a pesticide usually involves a chemical reaction with water.

Explanation:
Chemical degradation refers to breakdown by non-biological chemical reactions, and when water is involved, hydrolysis is the typical route. In hydrolysis, water acts as a reactant and helps split bonds in the pesticide, often influenced by factors like pH and temperature, yielding products that are usually more polar or less toxic. This distinguishes it from other degradation paths: photo-degradation is driven by light, microbial degradation involves living organisms, and enzymatic degradation relies on enzymes. The emphasis here is on chemical reactions with water as a key participant.
