Willowherbs have significant resistance to Roundup, repeated spraying will get control.
Basta is effective on willowherb and Asulox on bracken. Both of these are professional products.
Resolva 24h Concentrate has diquat as well as glyphosate, and works well on willowherbs.
You could also use lawn weedkillers to control willowherbs.
None of these chemcials can be allowed to drift onto garden plants.
