A triazine herbicide.
Pesticides used to destroy unwanted vegetation, especially various types of weeds, grasses (POACEAE), and woody plants. Some plants develop HERBICIDE RESISTANCE.
A pre-emergent herbicide.
A selective triazine herbicide. Inhalation hazard is low and there are no apparent skin manifestations or other toxicity in humans.

A group of islands in the southwest Pacific. Its capital is Wellington. It was discovered by the Dutch explorer Abel Tasman in 1642 and circumnavigated by Cook in 1769.
