Hatra is a post-emergence herbicide to control a wide range of grass weeds including black-grass and rye-grass and a range of broadleaf weeds in winter wheat crops. Hatra’s OD formula maximises the activity of mesosulfuron and iodosulfuron to give foliar and some root activity against black-grass, wild oats, rye grasses, meadow grasses, common chickweed and mayweeds.
Hatra can be applied in autumn or spring, between the 2-leaf stage of the crop up to flag leaf ligule just visible (GS12-39).
It can be tank-mixed with a residual herbicide such as Liberator (flufenacet and diflufencian) to increase protection against late germinating weeds.
