Can I use Prime Source Quinclorac 1.5L on a newly seeded lawn of fescue and ryegrass?

Grass is up and has been mowed twice


Per the product label for Prime Source Quinclorac 1.5L: The use of Quinclorac 1.5L Select before or after seeding or overseeding a turf area will not significantly interfere with the turf grass seed germination and growth of those grass types identified as tolerant or moderately tolerant.  According to Table 4 on the label it can be used before and at seeding on both fescue and perennial ryegrass.
