Tongue Scraper. In order to prevent tonsil stones itâs also a good idea to use a tongue scraper to scrape your tongue. Scraping your tongue helps with the prevention by removing excess bacteria that leads to more frequent tonsillitus episodes.nother common cause of tonsil stones is post nasal drip. The nasal drip will sometimes drip into the rear of your throat and will become very thick if your mouth is dry and not a lot of saliva is circulating.
Selective herbicide. SELECTIVE HERBICIDE. A selective herbicide is a weed killer that eradicates or stops the development of an invasive weed without damaging other species of plant. Selective herbicides are particularly useful when weeding lawns and turf, as they prevent gardeners from damaging lawn grass.
Nonselective herbicides kill all vegetation (including turfgrasses) and are used in lawn renovation or on weeds not controlled by selective herbicides. Herbicides can be further divided into preemergence and postemergence categories. Preemergence herbicides are applied prior to germination and emergence of weeds. These are typically used for controlling annual weeds. Postemergence herbicides are used for controlling weeds that have already emerged from the soil. They are either contact or systemic in nature.
