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.
Specifically, with preemergent herbicides, application timing, application coverage, and single versus split applications among other factors are crucial to the results obtained. Preemergent herbicides are typically applied late winter for control of many summer annual weeds, particularly annual grasses including crabgrass and goosegrass species. Application timing is critical with these products to obtain desired results.
