Hazard Information | Back Directory | [Uses]
Flucythrinate controls a wide range of insects on cotton, fruit trees,
vines, citrus, bananas, pineapples, olives, coffee, cocoa, hops, vegetables,
soyabeans, cereals, alfalfa, sugar beet, sunflowers and tobacco. | [Uses]
Insecticide. | [Uses]
Nonsystemic insecticide. | [General Description]
Flucythrinate belongs to the class of synthetic pyrethroids, primarily used to control Heliothis spp. in cotton and other insect pests in agricultural crops. | [Agricultural Uses]
Insecticide, Acaricide: Not approved for use in EU countries. Not currently registered in the U.S. Flucythrinate is a synthetic pyrethroid used to control pests in apples, cabbage, head lettuce, pears, corn and cotton, but it was used primarily on cotton.

Flucythrinate
is the (S)-2-(4-difluoromethoxyphenyl)-3-methylbutyrate
analog of fenvalerate, partially resolved. Its insecticide
action is approximately two times higher compared
with fenvalerate (138,142). | [Environmental Fate]
Surface Water. The half-life of ?ucythrinate in an estuarine environment is 34 days (Schimmel et al., 1983). Chemical/Physical. Hydrolyzes in aqueous solutions forming acetic acid and other compounds.
| [Metabolic pathway]
Flucythrinate is an analogue of fenvalerate and would be expected to
have a similar fate. | [Degradation]
Flucythrinate is a stable compound but it is readily hydrolysed at alkaline
pH to afford 2-(4-difluoromethoxyphenyl)-3-methylbutyric acid (2),
3PBAl(3) and cyanide ion. Its DT50 values at 27 °C are 52 days (pH 5) and
6.3 days (pH 9). It undergoes aqueous and soil surface photolysis with
DT50 values of 1-4 days and <2 days, respectively. The products formed
under aqueous conditions were 2 and 3. Compound 3 was oxidised to
3PBA (4) and reduced to 3PBAlc (5). The α-carbamoyl (amide) derivative
(6) of 3PBAlc was also detected. On soil surfaces, products were similar
with the exceptions that 3PBA was not formed and the α-amide (7) and
a-carboxy derivative (8) were formed. These are usually considered to be
products of thermal degradation (Dureja and Chattopadhyay, 1995). |
