Its been 10 days since we sprayed some of the surrounds with Rescue and over the last 2 days the effect is starting to be noticable. The Ryegrass firstly starts going a grey colour, eventually turning straw like, what is apparent in the initial stages of the herbicide effect on the Rye and Yorkshire Fog grasses that they do not grow, giving the apperance of a smoother surface. Obviously this means the herbicide is starting to kill the target grasses. The grasses in the rest of the surrounds at Malton are Annual Meadow grass, Bent and Fescue, the AMG and Bent do go yellow before recovering after about 3- 4 weeks, the Fescues stay green.
This is the 6th surround once more as it currently looks, below is the original photo before application
The areas of Rye grass will slowly die away, larger areas will need more intense overseeding when the coarse grass is removed.

I will update progress as the herbicide takes effect
