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.
Really a herbicide is a kind of pesticide. Cide means to kill, so a pesticide is just anything that's meant to kill a pest. So all of these are pesticides. So insecticides are meant to kill insects, fungicides are meant to kill fungi, herbicides are meant to kill plants.
