Cycloxydim is a mixture of several isomeric chemical compounds from the group of cyclohexanediones .
properties
Cycloxydim is a colorless solid that is practically insoluble in water. It is unstable in an acidic environment.
use
Cycloxydim is used as a herbicide against grasses. The effect is based on the inhibition of fatty acid biosynthesis, more precisely acetyl-CoA carboxylase (ACCase). It has been approved as a plant protection product in Germany since 1991 .
Corn belongs to the grass family and is therefore susceptible to cycloxydim. However, through mutagenesis , cycloxydim-tolerant maize has been developed. The herbicide is also used in rapeseed, beet, potato, lamb's lettuce, ornamental plants and field beans.
Admission
Cycloxydim has been approved for use as a herbicide in the countries of the European Union since June 1, 2011. The approval expires on May 31, 2023
, provided that no new approval is granted. In Germany, Austria and Switzerland, plant protection products (e.g. Focus, Focus Plus and Focus Ultra) with this active ingredient are approved.Web links
