• 개요

  Since 1970, benfluralin has been registered in the United States as a preemergent dinitroaniline herbicide. In 2004, the US Environmental Protection Agency (EPA) conducted an assessment to determine if pesticide products containing the active ingredient of benfluralin were eligible for pesticide reregistration. The criteria included meeting current human health and safety standards, and determining if the pesticide being used poses any unreasonable risks to human health and the environment. Results of the US EPA assessment were explained in the Reregistration Eligibility Decision (RED) of benfluralin. The RED document determined that pesticides with the active ingredient of benfluralin were eligible for reregistration provided certain stipulations listed in the RED document were met that included additional label requirements. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 3, all new pesticides used in the United States must be registered by the Administrator of the US EPA. There are 38 products registered for benfluralin.

• 화학적 성질

  Yellowish-orange crystalline solid. Commercial product is available as an emulsifiable concentrate.

• 용도

  Benfluralin is a preemergent herbicide registered to control monocot (one cotyledon: plant embryo with single ‘seed leaf’) and dicot (two cotyledon: plant embryo with two ‘seed leaves’) weeded species in commercial and residential applications. Target species for benfluralin include Johnson grass seedlings, chickweed, lamb quarters, purslane, knotweed, clover, and barnyard grass. Benfluralin affects seed germination and prevents weed growth by inhibition of root development. Absorbed by roots, benfluralin inhibits microtubule formation by binding to tubulin, thereby disrupting cell division and leading to microfibril disorientation. Benfluralin can be used alone or formulated with other structurally related preemergent herbicides. Benfluralin has been formulated with oryzalin, isoxaben, triclopyr and/or trifluralin. Various formulated types include emulsifiable concentrate, granules, soluble concentrate/liquid, and water dispersed granules. Benfluralin is formulated as granules in 42 end-use products and one product in the form of water dispersible granules. Applications can be by broadcast (granules and fertilizer mixed) and band treatment, golf course treatment, soil incorporated treatment, and spray with ground/sprinkler irrigation systems. Agricultural usage of benfluralin is predominately on lettuce, alfalfa, clover, birdsfoot trefoil, nonbearing fruit and nut trees, and vineyards.

• 정의

  ChEBI: A tertiany amino compound that is 2,6-dinitro-4-(trifluoromethyl)aniline in which the hydrogens attached to the aniline nitrogen have been replaced by one ethyl and one butyl group. It is used as a pre-emergence herbicide used for the control of grass and ther weeds in a range of food and non-food crops.

• 환경귀착

  Soil. Benfluralin degraded faster in flooded soils under anaerobic conditions than when oxygen was present. The major route of benfluralin degradation in flooded soil is the formation of polar products (Golab et al., 1970) including N-butyl-N-ethyl-α,α,α-trifluoro- 5-nitrotoluene-3,4-diamine, N-butyl-N-ethyl-α,α,α-trifluorotoluene-3,4,5-triamine, N butyl-N-ethyl-α,α,α-trifluorotoluene-3,4,5-triamine, N-butyl-α,α,α-trifluoro-2,6-dinitro p-toluidine, N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine, N-butyl-α,α,α-trifluoro-5- nitrotoluene-3,4-diamine, N-butyl-α,α,α-trifluorotoluene-3,4,5-triamine, N-ethyl-α,α,α- trifluoro-5-nitrotoluene-3,4-diamine, α,α,α-trifluoro-5-nitrotoluene-3,4-diamine, and α,α,α-trifluorotoluene-3,4,5-triamine (Williams, 1977). The rate of degradation was high est under anaerobic conditions.
  Nash (1988) reported a dissipation half-life of 2 days for benfluralin in soil.
  Photolytic. Though no products were identified, benfluralin is subject to photodegra dation by UV light (Worthing and Hance, 1991). A photodegradation yield of 79% was achieved after the herbicide in dry soil was subjected to sunlight for 7 days
  Chemical/Physical. In aqueous solutions (pH 5–9 and 26°C), benfluralin is stable up to 30 days (Worthing and Hance, 1991).

• 비 호환성

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Moderate heat causes decomposition that produces toxic vapors that can form an explosive mixture with air.

• 폐기물 처리

  Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed, Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Ultraviolet-radiation: This liquid herbicide is reported to be susceptible to decomposition by UV radiation.
