Beschreibung
Cymoxanil is a cyanoacetamide fungicide. It inhibits the mycelial growth of 12 isolates of
P. infestans with EC
50 values of 0.27-0.57 μg/ml. Cymoxanil (5-100 mg/l) inhibits the growth of several strains of
S. cerevisiae (IC
50s = 8-25 mg/l) but not
S. pombe,
K. marxianus,
P. anomala, or
C. utilis. A spray application of cymoxanil (1 mg/mL) one day after inoculation of potato leaves with
P. infestans and cucumber leaves with
P. cubensis reduces blighted leaves by 79 and 60%, respectively. It is toxic to rats with an acute LD
50 value of 3.8 mmol/kg. Formulations containing cymoxanil have been used to prevent fungal growth on crops and treat late potato blight in agriculture.
Chemische Eigenschaften
A white to peach (pale pink) crystalline solid.
Verwenden
Cymoxanil is a fungicide applied as a seed treatment or as a foliar application to the plants to control late blight.
Definition
ChEBI: A member of the class of ureas that is urea in which the two nitrogen atoms are substituted by an ethyl group and a 2-cyano-2-(methoxyimino)acetyl group respectively. A fungicide used to control Peronosporales on a range of crops including vin
s, hops and potatoes.
Landwirtschaftliche Anwendung
Fungicide: Cymoxanil is applied as a seed treatment to cut potato seed pieces or as a foliar to control late blight.
Handelsname
CURZATE®; DPX 3217®; DPX 3217 M®; DPX-T3217®; EVOLVE®; MZ-CURZATE®; TANOS® Cymoxanil
Kontakt-Allergie
Cymoxanil, an urea derivative, is included (10%) with dithianone (25%) in Aktuan?. It is a fungicide agent, possibly sensitizing agricultural workers
mögliche Exposition
Cymoxanil is a cyanoacetamide oxime
fungicide applied as a seed treatment to cut potato seed
pieces or as a foliar to control late blight.
Stoffwechselwegen
Cymoxanil is rapidly degraded in neutral to alkaline aqueous solutions
and is metabolised extensively in soil, plants and animals. Cymoxanil
degradation follows a series of cyclisation and /or hydrolysis reactions to
form 5- and 6-membered ring compounds and shorter chain keto acids
and amides. In plants and animals, cymoxanil is metabolised to form
natural products, especially glycine.
Stoffwechsel
Animals
Radiolabeled cymoxanil is metabolized in the goat to
natural products, including fatty acids, glycerol, glycerin,
and other amino acids, lactose, and acid-hydrolysable
formyl and acetyl groups.
Plants
Rapid degradation to naturally occurring amino acids,
particularly to glycine, with subsequent incorporation into
constituent sugars, starch, fatty acids, and lignin (6).
Soil
In laboratory soils, DT
50 0.75–1.5 d (5 soils, pH range
5.7–7.8, o.m. 0.8–3.5%). In the field, DT
50 (bare soil)
0.9–9 d.
Versand/Shipping
UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz-
ardous material, Technical Name Required.
Inkompatibilitäten
Slowly hydrolyzes in water, releasing
ammonia and forming acetate salts. Light sensitive.
Waste disposal
Do not discharge into drains
or sewers. Burn in incinerator specifically designed for pes-
ticide disposal or dispose as a Hazardous waste in a landfill
approved and licensed for the disposal of pesticides.
Consult with environmental regulatory agencies for guid-
ance on acceptable disposal practices. Ultimate disposal of
the chemical must consider: the material’s impact on air
quality; potential migration in soil or water; effects on ani-
mal, aquatic, and plant life; and conformance with environ-
mental and public health regulations.
