A detailed overview of the herbicide sulfentrazone
Sulfentrazone[edit]
Sulfentrazone is a selective pre-emergence and post-emergence herbicide used primarily in agriculture to control broadleaf weeds and grasses. It belongs to the chemical class of triazolinones and is known for its effectiveness in controlling a wide range of weed species.
Chemical Properties[edit]
Sulfentrazone is characterized by its chemical formula C11H10Cl2F3N3O3S. It is a crystalline solid with a molecular weight of 387.18 g/mol. The compound is relatively stable under normal environmental conditions and has a low solubility in water.
Mode of Action[edit]
Sulfentrazone works by inhibiting the enzyme protoporphyrinogen oxidase (PPO), which is crucial in the biosynthesis of chlorophyll. This inhibition leads to the accumulation of protoporphyrin IX, a photodynamic compound that causes lipid peroxidation and cell membrane disruption in plants. As a result, treated weeds exhibit symptoms such as chlorosis and necrosis, ultimately leading to plant death.
Applications[edit]
Sulfentrazone is widely used in the cultivation of crops such as soybeans, tobacco, sugarcane, and peanuts. It is applied to the soil surface or incorporated into the soil before or after planting. The herbicide is effective against a variety of weed species, including pigweed, lambsquarters, and foxtail.
Environmental Impact[edit]
Sulfentrazone has a moderate persistence in the environment, with a half-life ranging from 24 to 113 days depending on soil conditions. It is primarily degraded by microbial activity. While it has a low potential for leaching into groundwater, sulfentrazone can pose risks to aquatic organisms if it enters water bodies through runoff.
Safety and Handling[edit]
When handling sulfentrazone, it is important to follow safety guidelines to minimize exposure. Protective clothing, gloves, and eye protection should be worn. In case of accidental exposure, affected areas should be washed thoroughly with water. The herbicide should be stored in a cool, dry place away from food and feed.
