Where are pesticides used? Pesticides have a wide range of intended uses in agriculture (e.g. insecticides to prevent crop damage; fungicides to prevent plant disease), forestry, industry (e.g. material preservatives in paints or metal working fluids), and society (e.g. personal insect repellents).
How do herbicides work?
Herbicides kill plants by causing a build up of a toxic substance, where the toxic compounds stay at reasonably low levels. By inhabiting the target site (enzyme), herbicides cause substances to build up and damage the plant. This is how the herbicide glyphosate works. … The plant essentially grows it self to death.
