The dry weather continues. At the time of writing large parts of my area have received less than 25mm of rain this autumn. As such the seedbeds are still relatively open, and the residual herbicides used to date are unlikely to have created as good a chemical seal as last year.
That said, you can see blackgrass being affected by the residuals. The fact the blackgrass emergence has been delayed, combined with earlier drilling and fewer stale seedbeds could result in a challenging year on some farms.
To help control the annual grass weeds this autumn, I am eager to use a contact chemical such as iodosulfuron-methyl-sodium or pyroxsulam. Both these products will need to be applied with a residual partner.
