A ready-to-use formulation containing 60g/l acetic acid Controls annual and perennial weeds FOR USE ONLY AS AN AMATEUR WEEDKILLER DIRECTIONS FOR USE It is good practice to wear gloves when using this product although this is not a requirement. A minimum interval of 7 days must be observed between applications. When To Use: RHS Weed killer is a non-selective weed and moss killer active against most soft plant tissue with which it comes in contact. Weeds or moss are controlled by covering their foliage completely and evenly with spray. Soon after spraying, the foliage of treated moss or weeds begins to wither and die. Plant roots are not killed and new foliage may grow, particularly from the roots of perennial weeds. Annual weeds with small roots and moss may die back completely but re-treatment will usually be necessary, especially to keep down perennial weeds. Use to achieve control of weeds and/or moss. Best results are achieved against moss and tender, small weeds less than 10 cm high. Ideally spray in spring and repeat as necessary over the growing season, up to a maximum of 6 applications per year 2 x 5L Weed Killer NOTE: The colour of the bottle may vary
