That tender new growth will be more susceptible to the chemical
first tillage stage plants are more suseptable to herbicides, however wacking a mature plant down is a different story and counterproductive. You would want more foliage area to absorb the herbicide not less. Most herbicide labels recommend NOT mowing prior to herbicide applications 48 hours before or after application.
