Hi guys. I have a small lawn care company that is located in Minnesota. I have a couple of questions that I hope you can help me with. I tank mix everything into a liquid application of herbicide and weed control. Tough weeds: This year I have had a hard time controlling some of the more hardy weeds. Creeping Charlie, violets and Oxalis (wood sorrel?) are my main pain in the butts. In May I use trimec for weed control and in June and early July I use Surge as a more aggressive herbicide (Both at 4 pints per acre). This year I have seen very poor results on the three weeds listed above. The temps have been very high and the moisture very low this past month. Any advice? Crab grass: In the spring I used the preemergant Resolve at the high rate. This year the CG is exploding. I would like some post emerg. options. I have backpacked drive in the past but many of the lawns have a lot of CG so the entire lawn needs to be sprayed. Do any of you tank mix cg control in with your normal weed control and fertilization applications? I am concerned about burn, effectiveness and expense since products like Drive are not cheap to tank mix.
