Using seasonal treatment techniques can provide a quick fix, but only handle infestations for the short term. Treatment can be used effectively with methods to solve and improve land conditions.
Mechanical - topping/cutting rushes just before seeding can knock back growth. Cutting when the plant has seeded may spread infestation further.
Chemical - careful consideration should be taken before using any herbicides as they pose a significant risk to water quality, especially in rivers abstracted from for drinking water.
Lower risk option. Uses significantly less herbicide with direct application to rush.
Risk of spray drift. Can use lower risk chemical. Only suitable for small infestations.
High risk of spray drift. Commonly uses MCPA which takes significantly longer to break down in the environment. More costly option.
