A bed with a duvet. A duvet (/ËdjuËveÉª/, /ËduËveÉª/, or US /duËËveÉª/; from the French duvet [dyvÉ] down) is a type of bedding consisting of a soft flat bag filled with down, feathers, wool, silk or a synthetic alternative, and typically protected with a removable cover, analogous to a pillow and pillow case.
ALS Inhibitors. ALS Inhibitors are a family of herbicides. Herbicides that inhibit acetolactate synthase (ALS), the enzyme common to the biosynthesis of the branch-chain amino acids (valine, leucine, and isoleucine), affect many species of higher plants as well as bacteria, fungi, yeasts, and algae.
Herbicides are available in two main types: nonselective and selective. The nonselective variety is used to kill all growth and is generally reserved for agricultural use or for clearing large or heavily overgrown areas. On the other hand, a selective herbicide is used to target certain types of plant life.This form works to curb growth, usually through some type of hormone disruption, and should not affect other vegetation.n the other hand, a selective herbicide is used to target certain types of plant life.
