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.
Chemical Weed Control. Herbicides are chemicals that kill or alter the normal growth of weeds. They can be divided into two main groups: selective and nonselective. Selective herbicides are those that control the target weed(s) without damaging desirable turfgrass species.Nonselective herbicides kill all vegetation (including turfgrasses) and are used in lawn renovation or on weeds not controlled by selective herbicides.elective herbicides are those that control the target weed(s) without damaging desirable turfgrass species. Nonselective herbicides kill all vegetation (including turfgrasses) and are used in lawn renovation or on weeds not controlled by selective herbicides.
