Metominostrobin is a chemical compound from the group of methoxyiminoacetamides and strobilurins , which is used to control fungi in agriculture.

properties

Metominostrobin is a white solid that is poorly soluble in water. Because of the asymmetrically substituted oxime double bond, metominostrobin occurs as an E / Z isomer pair . Since the E isomer is 5 to 20 times more effective than the Z isomer, the E isomer is predominantly used.

use

Metominostrobin is used as a fungicide in rice against the fungus Magnaporthe grisea and is approved in Asian countries. The connection was discovered in 1998 by the Shionogi company .
