Identification

Common Name

Glufosinate

Class

Small Molecule

Description

Glufosinate or its ammonium salt DL-phosphinothricin is an active ingredient in several nonselective systemic herbicides such as Basta, Rely, Finale, Ignite, Challenge, and Liberty. It interferes with the glutamine biosynthetic pathway that binds to the glutamate site of the enzyme. Glufosinate-treated plants die due to a buildup of ammonia and a cessation of photosynthesis due to lack of glutamine.

Toxicity Profile

Route of Exposure

Not Available

Mechanism of Toxicity

Glufosinate irreversibly inhibits the enzyme glutamine synthetase, which decreases ammonia detoxification. Increased ammonia levels lead to impairment of photorespiration and photosynthesis in plants. (1)
