	==~~Chemistry~~==		==Sulfentrazone==
	Sulfentrazone is a ~~white, crystalline solid with a slight aromatic odor~~. It is ~~not soluble~~ in ~~water and has~~ a ~~low vapor pressure, making it unlikely to volatilize into the air~~. It is stable under normal ~~temperatures~~ and ~~pressures, but it may decompose when exposed to light~~.		[[File:Sulfentrazone.svg\|thumb\|right\|Chemical structure of sulfentrazone]]
			'''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==
			Sulfentrazone is characterized by its chemical formula C<sub>11</sub>H<sub>10</sub>Cl<sub>2</sub>F<sub>3</sub>N<sub>3</sub>O<sub>3</sub>S. 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==		==Mode of Action==
	Sulfentrazone ~~acts as a~~ [[protoporphyrinogen oxidase]] (PPO) ~~inhibitor~~. ~~PPO is an enzyme~~ that is ~~essential for~~ the ~~synthesis~~ of [[~~chlorophyll~~]], the ~~molecule that plants use to convert sunlight~~ into ~~energy~~. ~~By inhibiting PPO, sulfentrazone causes~~ a ~~buildup~~ of ~~protoporphyrin IX~~, ~~which~~, ~~when exposed to light~~, ~~produces reactive oxygen species that damage cell membranes~~ and ~~lead to plant death~~.		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==
			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]].

	==~~Use~~==		==Environmental Impact==
	Sulfentrazone ~~is used to control~~ a ~~variety of weeds~~, ~~including [[broadleaf weeds]], [[sedges]], and some [[grasses]]~~. It is ~~used in a variety of settings, including [[turf]], [[ornamental plants]], and certain [[agricultural crops]]~~. ~~It is typically applied as~~ a ~~pre-emergent herbicide~~, ~~meaning~~ it ~~is applied to the soil before the weeds emerge~~.		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==		==Safety and Handling==
	~~Sulfentrazone~~ is ~~classified as a Category C (possible human carcinogen) by the [[Environmental Protection Agency]] (EPA)~~. ~~It is not considered to~~ be a ~~significant risk to wildlife or the environment when used as directed~~.		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.

'''Sulfentrazone''' is a [[herbicide]] used in the control of [[broadleaf weeds]], [[sedges]], and some [[grasses]]. It is a member of the [[triazinone]] family of chemicals, which act as [[protoporphyrinogen oxidase]] inhibitors. Sulfentrazone is used in a variety of settings, including [[turf]], [[ornamental plants]], and certain [[agricultural crops]].

==Chemistry==
Sulfentrazone is a white, crystalline solid with a slight aromatic odor. It is not soluble in water and has a low vapor pressure, making it unlikely to volatilize into the air. It is stable under normal temperatures and pressures, but it may decompose when exposed to light.

==Mode of Action==
Sulfentrazone acts as a [[protoporphyrinogen oxidase]] (PPO) inhibitor. PPO is an enzyme that is essential for the synthesis of [[chlorophyll]], the molecule that plants use to convert sunlight into energy. By inhibiting PPO, sulfentrazone causes a buildup of protoporphyrin IX, which, when exposed to light, produces reactive oxygen species that damage cell membranes and lead to plant death.

==Use==
Sulfentrazone is used to control a variety of weeds, including [[broadleaf weeds]], [[sedges]], and some [[grasses]]. It is used in a variety of settings, including [[turf]], [[ornamental plants]], and certain [[agricultural crops]]. It is typically applied as a pre-emergent herbicide, meaning it is applied to the soil before the weeds emerge.

==Safety==
Sulfentrazone is classified as a Category C (possible human carcinogen) by the [[Environmental Protection Agency]] (EPA). It is not considered to be a significant risk to wildlife or the environment when used as directed.
