What are herbicides used for?
Herbicides are chemicals used to manipulate or control undesirable vegetation. Herbicide application occurs most frequently in row-crop farming, where they are applied before or during planting to maximize crop productivity by minimizing other vegetation.
How do insecticides work on insects?
Systemic insecticides kill insects when they eat the plant and ingest the insecticide chemical. ... Organochlorine compounds work on insects by opening what's known as the sodium ion channel in the neurons or nerve cells of insects, causing them to fire spontaneously.

Where are herbicides used?
Herbicides are widely used in agriculture and in landscape turf management. They are applied in total vegetation control (TVC) programs for maintenance of highways and railroads. Smaller quantities are used in forestry, pasture systems, and management of areas set aside as wildlife habitat.
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.
What are herbicides give example?
> Herbicides are the pesticides which are most commonly used to kill unwanted plants like weeds in farms or crops are. Examples of herbicides - Acetochlor, Atrazine, Amitrole, Dinosep.
