erminology
Herbicides are classified/grouped in various ways e.g. according to the activity, timing of application, method of application, mechanism of action, chemical family. This gives rise to a considerable level of terminology related to herbicides and their use.
Intended outcome
Control is the destruction of unwanted weeds, or the damage of them to the point where they are no longer competitive with the crop.
Suppression is incomplete control still providing some economic benefit, such as reduced competition with the crop.
Crop safety, for selective herbicides, is the relative absence of damage or stress to the crop. Most selective herbicides cause some visible stress to crop plants.
Defoliant, similar to herbicides, but designed to remove foliage (leaves) rather than kill the plant.
Selectivity (all plants or specific plants)
