Cymoxanil

Cymoxanil is 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 vines, hops and potatoes. It has a role as a xenobiotic, an environmental contaminant and an antifungal agrochemical. It is a nitrile, an oxime O-ether, a member of ureas and an aliphatic nitrogen antifungal agent. — ChEBI
