Hi guys, I am from Northern NJ, just got my pest license this year and we are treating around 200k sq ft total. I have been very happy with products such as PowerZone in the Spring and than switched over to Surge for any post emerg weed activity. My question is, I'm starting to bring in new clients whose lawns haven't been treated this year at all,no pre-emerg or anything. So obviously this time of year crabgrass is out of control. What is the best product out there in terms of eliminating the crabgrass while at the same time not causing too much damage to the existing turf? Do I go with Drive75 or Q4plus. I would like to get these weeds out of here soon, as in about another 5-6 weeks I plan on aerating and seeding. Thanks for the advice. Hope everyone is staying cool with these hot summer days.
