Quinclorac Select 75 DF Herbicide may be applied post emergence to residential and nonresidential turfgrasses (refer to Table 1) for the control of many broadleaf and grass weeds.

Quinclorac Select 75 DF Herbicide is absorbed by foliage and roots and translocated throughout the plant. The control symptoms exhibited by broadleaf weeds include leaf and stem curl or twisting, and chlorosis. Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death. Refer to Tables 1, 2 and 3 for turfgrass tolerance and susceptible weed species.

QRegulated in NYS?
I need a professional strength post emergent herbicide as the commercially available herbicides at lowes and home depot wont kill foxtail. Professional sevices are price gouging us here in NY. I will buy this product asap if it is non regulated in NY. Thanks Robert
