I'll try this as I have horsetail every where. I sprayed the horsetail and other weeds in the cracks of the pavement this spring with a weed killer. This caused all the weeds to die except for the horsetail which seem is bigger and healthier without any other competition. It is now spreading to the lawn. I'll never get rid of it completely as it is coming in from the neighbour's garden.
