Description
White to beige solid; [HSDB] Colorless crystalline solid; [MSDSonline]
Sources/Uses
Used as post-emergence herbicide for control of broad-leaved and grassy weeds; Not marketed in the US; WHO has classified this pesticide as "believed to be obsolete or discontinued; [HSDB]
Comments
The triazine herbicides disrupt photosynthesis in plants; they are not highly toxic in mammals; In lethal-dose animal studies, adverse effects included CNS disturbance, decreased hemoglobin, and liver and kidney injury; [HSDB] For the triazine herbicides, systemic toxicity unlikely unless large amounts are ingested; May cause irritation; [EPA Pesticides, p. 121]
