After the mild, dry spring, it may be as good an opportunity as any to control rushes in grassland. The first step to controlling rushes is topping. This will promote green regrowth of rushes, which are more capable of taking in herbicide. After topping, spraying with products such as MCPA or 2,4-D, applied at their recommended rates and by a professional registered user, are particularly effective in decreasing the area infested.
