(32168), Hi-Yield Killzall Weed And Grass Killer Concentrate, Weed & Grass Stopper 12# Category: Herbicides Herbicides are a type of chemical pesticide that is used to control the growth and spread of unwanted plants. They work by inhibiting or killing the cells responsible for plant growth, which stops the plant from growing or reproducing. There are many different types of herbicides available on the market, each with its own unique properties and uses. The products in this category all belong to the glyphosate family of herbicides, which is one of the most commonly used herbicide classes. Glyphosates work by inhibiting an enzyme called EPSP synthase, which is responsible for the production of a key amino acid that plants need to grow. When this enzyme is inhibited, the plant cannot produce enough of the amino acid and eventually dies. One of the main advantages of glyphosate herbicides is their broad-spectrum activity, meaning they can kill a wide range of plants, including grasses, weeds, and even some trees. They are also relatively easy to apply and do not require specialized equipment or training to use effectively. However, glyphosates have been the subject of controversy in recent years due to concerns about their potential long-term effects on human health and the environment.
