Description

Fenoxycarb is a yellow granular solid, broad-spectrum insect growth regulator and nonneurotoxic carbamate. Fenoxycarb is almost insoluble in water, but soluble and very soluble in hexane, acetone, chloroform, diethyl ether, and methanol. Fenoxycarb is a GUP, meaning the user or the pesticide applicator does not need a license. It is used to control a wide variety of insect pests, as a fi re ant bait and for fl ea and mosquito control. It is also used for the control of cockroaches, butterfl ies


ChEBI: Fenoxycarb is a carbamate ester that is the O-ethyl carbamate of 2-(4-phenoxyphenoxy)ethylamine. It has a role as a juvenile hormone mimic, an environmental contaminant, a xenobiotic and an insecticide. It is an aromatic ether and a carbamate ester. It is functionally related to a 4-phenoxyphenol.

Drug Information

Fenoxycarb is practically non-toxic to mammals after oral ingestion. The oral LD50 for rats is greater than 10,000 mg/kg and the dermal LD50 for rats is greater than 2,000 mg/ kg. Direct application of fenoxycarb on the skin of laboratory rats caused labored breathing and diarrhea in animals. Although fenoxycarb does not irritate the skin, it is an eye irritant. The liver is the primary organ affected by fenoxycarb in long-term animal studies. Prolonged period of oral exposures to rats and dogs with very low doses of fenoxycarb caused no health effects in the animals, while high concentrations caused adverse effects to the liver of rats, mice, and dogs. Reports on the teratogenicity and mutagenicity of fenoxycarb are not available in the literature.

Fenoxycarb Use and Manufacturing

Insect growth regulator. Its molecular structure has a carbamate gene, but its insecticidal effect is non-neurological, showing strong juvenile hormone activity to most insects, which can prevent eggs from hatching, inhibit adult metamorphosis and larval stage molting, resulting in late larval stage Or pupa death, sometimes the agent will also inhibit the growth of adult or larvae and appear precocious. Its characteristics: broad insecticidal spectrum, both stomach toxicity and contact killing; high efficiency, low toxicity; long residual effect period, no pollution to the environment; can effectively prevent antibiotics and be safe to natural enemies. It can be used in fruit tree leaf moths, carnivorous insects, cotton armyworms and borers, pear yellow wood lice, citrus scale insects, and storage pests, red fire ants, etc., generally use 0.0125% ~ 0.025% chemical treatment , Sometimes 0.006%.


Fenoxycarb is mainly used to control Lepidoptera, scale insects and suckers on fruit, cotton, olives, vines and ornamentals. It is used to control Coleoptera and Lepidoptera in stored products, and cockroaches, fleas, mosquito larvae and fire ants in public health situations.
