Is 'defoliate' only used for negative actions?

Predominantly yes, due to its association with chemical agents and environmental harm. However, in controlled agricultural contexts (e.g., defoliating cotton before mechanical picking), it can be a neutral technical term.

What's the difference between 'defoliate' and 'prune'?

'Prune' involves selective cutting of branches to shape or improve health. 'Defoliate' specifically means removing leaves, often completely and indiscriminately, and usually by non-mechanical means (like chemicals or pests).

Can 'defoliate' be used as a noun?

No. The related noun is 'defoliation' (the process or result of defoliating) or 'defoliant' (the chemical agent used).

Is there a biological term for an agent that causes defoliation?

Yes. A 'defoliator' is an insect or other organism that feeds on and removes leaves. A 'defoliant' is a chemical herbicide used for the same purpose.
