herbicide
Let an agent explain herbicide types and modes of action, relay label, safety and regulatory information from authorities, describe environmental and health debates with attribution, and support weed management questions at a general level.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain herbicide types and modes of action, relay label, safety and regulatory information from authorities, describe environmental and health debates with attribution, and support weed management questions at a general level.
A pesticide used to kill or control unwanted plants, classified by selectivity as selective or non-selective, by timing as pre-emergent or post-emergent, and by chemical family such as glyphosate, sulfonylureas, diphenyl ethers, aryloxyphenoxypropionates and triclopyr-based products, used in agriculture, forestry, rights of way and gardens; herbicides are regulated for approval, labelling, residues and environmental effects, and their health and ecological impacts are studied and debated.
What it is for: Chemicals for controlling unwanted plants.
It can be explain types and modes of action; relay safety and regulation; describe debates; support weed management.
