Cymoxanil 57966-95-7 98% TC, 72% WP



Introduction: 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 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.

Animals In rats, cymoxanil was readily absorbed through the intestines; the majority of the dose was excreted in the urine. The proposed metabolic pathway involves hydrolysis of cymoxanil and then degradation to glycine. Plants Degraded to glycine with subsequent incorporation into natural products (proteins and starch). Soil/Environment In lab. soils, DT50 0.75-1.6 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. In aquatic studies, DT50 <1 d. Koc 38-237. Cymoxanil is mobile, adsorption Freundlich K 0.29 to 2.86 in four soil types.               

Usage: Cymoxanil was developed by DuPont. It is a fungicide used to control pathogens on a range of crops including potatoes and other crops.

Application: Mode of action Foliar fungicide with protective and curative action. Has contact and local systemic activity, and also inhibits sporulation. Uses Control of Peronosporales, especially Peronospora, Phytophthora, and Plasmopara spp. Normally used in combination with protectant fungicides (to improve residual activity) on a range of crops, including vines, hops, potatoes, and tomatoes.
