Description and Uses

Flurprimidol is a plant growth regulator used to retard growth in a wide range of mono- and dicotyledonous weed species. It is moderately soluble in water, has a low volatility but there is some risk of drift under certain conditions. Generally, it is not persistent in soils or water-sediment systems. Regarding human health there is some concern that it may be a reproduction/developmental toxin. Oral mammalian toxicity is moderate. Toxicity to biodiversity is low to moderate.

Growth retardant for grasses.
