DL-Phosphinothricin is a herbicide commonly used in plant molecular biology and plant tissue culture. It is the ammonium salt of glufosinate. It is also known as glufosinate ammonium.

The herbicide is a broad spectrum herbicide which is comparatively biodegradable, similar to glyphosate.[1] Glufosinate is sold under trade names Basta, Buster and Liberty. Crops have been developed (genetically engineered) which are resistant to this herbicide through the insertion of the bar gene[2] into plants.
