Description and Uses

Ancymidol is a plant growth regulator. It is volatile and moderately soluble in water. It is not persistent in soil systems and generally not persistent in water. It is moderately mobile and so there is a risk of leaching to groundwater under some conditions. It has a moderate mammalian toxicity but is not expected to bioaccumulate. Ancymidol is moderately toxic to fish, aquatic invertebrates, aquatic plants and honeybees, however, it is less toxic to algae and birds.

Plant growth regulator.
