Determination of diflubenzuron in apples by gas chromatography

Journal of Chromatography A, 1997
A method for the determination of residues of the insecticide diflubenzuron, 1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)urea, in apples using gas chromatography with electron-capture detection has been developed and validated. The three solvents ethyl acetate, acetone and dichloromethane were tested for extraction of diflubenzuron residues from apples ...

Effects of diflubenzuron on the mouse liver

Journal of Applied Toxicology, 1986
AbstractDiflubenzuron (DFB), a potent inhibitor of insect chitin synthesis, was administered to Swiss Webster mice in a 30‐day oral intubation study. Animal groups received either no treatment, vehicle control (Polyehylene glycol 400), or DFB suspensions at doses of 125, 500, and 2000 mg/kg body weight.

Effect of diflubenzuron on an estuarine crustacean

Bulletin of Environmental Contamination and Toxicology, 1979
In a review of one of the newer insecticides, diflubenzuron (Dimilin, TH-6040, [ i( 4-chloropher@l )-3( 2,6-dlfluorobenzoyl ) urea]), MARX (1977) emphasized that its ability to i~pair chltin synthesis, leading to toxicity in insects, is useful for controlling several insect pests.

The accumulation and elimination of diflubenzuron by fish

Bulletin of Environmental Contamination and Toxicology, 1979
In summary, diflubenzuron is accumulated from water into fish tissues at levels up to 80 fold within 24 hr when fish are exposed to concentrations of 10 ppb. Within the concentration range of 1-10 ppb, the amount accumulated in a 24 hr exposure is proportional to concentration. After 24 to 48 hr exposure fish degrade and eliminate diflubenzuron and the

Pharmacokinetics of diflubenzuron in two types of chickens

Journal of Toxicology and Environmental Health, 1984
Pharmacokinetic parameters of [14C]diflubenzuron, N-([(4-chlorophenyl) amino]-carbonyl)-2,6-difluorobenzamide, in White Leghorn (WL) egg-production chickens and Rhode Island Red/Barred Plymouth Rock (RIR/BPR) meat-production chickens after single 1-mg/kg intravenous and single 5-mg/kg oral doses were investigated to explain a breed-related egg residue ...

Metabolism of Diflubenzuron in Lizard (Eremias argus) and Comparative Toxicity of Diflubenzuron and Its Metabolite

Journal of Agricultural and Food Chemistry, 2018
The metabolic process of diflubenzuron in rat or fish has been well studied, but little is known about its elimination pathway in lizard. The current study predicted the metabolic route of diflubenzuron in lizard feces and compared the toxicity of diflubenzuron and 4-chloroaniline on lizard thyroid system.
