| Cymoxanil Usage And Synthesis |
| Description | Cymoxanil was first introduced in 1977. It is an acetimide compound used as both a curative and preventative foliar fungicide. In Europe it is being sold for use on grapes, potatoes, tomatoes, hops, sugarbeets and other vegetable crops. Cymoxanil is currently not registered in the U.S. Cymoxanil is a fungicide used on crops including potatoes, tomatoes, and grapes. Cymoxanil is not registered for non-crop use in any country. Cymoxanil's mode of action is as a local systemic. It penetrates rapidly and when inside the plant, it cannot be washed off by rain. It controls diseases during the incubation period and prevents the appearance of damage on the crop. The fungicide is primarily active on fungi belonging to the Peronosporales order: Phytophthora, Plasmopara, and Peronospora. |
| Physical Properties | Technical cymoxanil is a peach colored crystalline, odorless solid. |
| Toxicity | Technical cymoxanil has low acute toxicity. The acute oral LD50 is 960 mg/kg in rats. The acute dermal LD50 is >2,000 mg/kg in rabbits. The 4-hour rat inhalation LC50 is >5.06 mg/L. Minimal transient irritation of the skin and eyes was observed in rabbits. Cymoxanil did not cause skin sensitization in guinea pigs. Cymoxanil should be classified as Toxicity Category III for oral and dermal toxicity and Toxicity Category IV for inhalation toxicity and skin and eye irritation potential. Absorption, Distribution and Excretion Cymoxanil is rapidly absorbed and maximum concentrations in the blood and plasma is reached within 4 hours after dosing. Rapid and almost complete elimination of the administered radioactive dose was observed in urine and feces within 48 hours. Excretion is primarily by urine (64-75%), fecal (16-24%) and expired air (< 5%) of the administered dose. There is no significant difference in residue profiles or elimination rates between sexes, dose levels, or single or multiple dosing. No evidence of bioaccumulation was detected. DPX-T3217 is metabolized extensively and only trace level of the administered (14)C-cymoxanil was detected in the urine and feces. |

| Uses | Efficient fungicide |
| Chemical Properties | A white to peach (pale pink) crystalline solid. |
| Uses | Cymoxanil is a fungicide applied as a seed treatment or as a foliar application to the plants to control late blight. |
| Uses | Agricultural fungicide. |
| Uses | Cymoxanil is a foliar applied fungicide which provides preventive and curative control of pathogen species of the order Peronosporales (eg. Phytophthora, Plasmopara and Peronospora) in grapes, potatoes, tomatoes, hops, tobacco and cucurbits. |
| 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. |
| Agricultural Uses | Fungicide: Cymoxanil is applied as a seed treatment to cut potato seed pieces or as a foliar to control late blight. |
| Trade name | CURZATE®; DPX 3217®; DPX 3217 M®; DPX-T3217®; EVOLVE®; MZ-CURZATE®; TANOS® Cymoxanil |
| Contact allergens | Cymoxanil, an urea derivative, is included (10%) with dithianone (25%) in Aktuan?. It is a fungicide agent, possibly sensitizing agricultural workers |
| Potential Exposure | Cymoxanil is a cyanoacetamide oxime fungicide applied as a seed treatment to cut potato seed pieces or as a foliar to control late blight. |
| Metabolic pathway | 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. |
| Metabolism | 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, DT50 0.75-1.5 d (5 soils, pH range 5.7-7.8, o.m. 0.8-3.5%). In the field, DT50 (bare soil) 0.9-9 d. |
