Metalaxyl-M

Metalaxyl-M is the more active of the two enantiomers of the phenylamide fungicide metalaxyl; metalaxyl is currently registered in more than 80 countries with uses on more than 60 crops. 1996 Mefenoxam (metalaxyl-M) first registered for use in NYS. Metalaxyl-M is the first enantiomeric form of a fungicide introduced into the market. When used as seed-treatment, soil treatment or foliar application against fungi of the order Peronosporales, it provides the same excellent level of efficacy as metalaxyl but at half the application rate. Mefenoxam is more commonly used than metalaxyl in most pesticide products registered in NYS today.
