Description and Uses
Flumetsulam is a selective, post-emergence herbicide used mainly to control broadleaved weeds and some grasses. It is highly soluble in water and has a low volatility. It can be moderately persistent in some soil systems and very persistent, depending on conditions, in water bodies. There is a significant potential for it to leach to groundwaters. Its mammalian oral toxicity is low and it can be an irritant for skin and eyes. Other data related to chronic health is missing. Generally, it has a low toxicity for most biodiversity.
Flumetsulam is a ighly active herbicide of the triazolopyrimidine sulfonanilide class. Flumetsulam act by inhibiting acetolactate synthase. Flumetsulam exhibits broad spectrum activity on broadleaf weed species with selectivity to several major agronomic crops in soil and foliar applications.
