Usage

Description

Amidosulfuron is a broad spectrum herbicide that is used to control broad-leaved weeds. It is volatile, highly soluble in water and, based on its chemical properties, has a high potential for leaching to groundwater. It is not persistent in soil systems but may be persistent in water under certain conditions.

Toxicity

Amidosulfuron has a low mammalian toxicity and would not be expected to bioaccumulate. Amidosulfuron is moderately toxic to most terrestrial and aquatic species.

Uses

Different sources of media describe the Uses of 120923-37-7 differently. You can refer to the following data:
1. Herbicide.
2. Amidosulfuron, is used as pesticide and herbicides.

Metabolic pathway

The hydrolysis of 14C-amidosulfuron in buffer aqueous solutions under various conditions results in 2-amino- 4,6-dimethoxypyrimidine as the major hydrolyzed product. In soils, O-demethylated amidosulfuron is the major degradation product. In mammals and plants, primary hydroxylation at the pyrimidine ring is a characteristic degradation reaction yielding 5-hydroxyamidosulfuron.
