I've been using Resolva for years to treat mainly wild violet and broadleaf weeds, never had any issues in the past. Roll back to three weeks ago used the same product (Resolva Concentrate for lawns) as before, diluted approx 10ml in 8 liters of water and then sprayed over the lawn where weed growth was prominent, then during last weeks heat wave patches like this appear all across the lawn where I have sprayed, initially I was hoping that this was because of the sun burning the grass but it appears too random in places. Am I able to save the lawn by using a high dose nitrogen feed and watering, or do I suck it up and reseed in September time.

Thanks
