Uncle's Tip: Always add a few drops of Uncle's STIKIT to Speed Zone. STIKIT is a surfactant, A.K.A spreader sticker, and will help Speed Zone stick to waxy leaf of clover, oxalis and dandelions.
Using Speed Zone in the fall, you won’t have the pleasure of watching your weeds die overnight. That twisting, shriveling and yellowing you see the next day with a summer application is not as obvious, but next spring the weeds will be gone.
Will Speedzone affect overseeding? Yes, always wait 7-10 days after application before overseeding. Do not use Speed Zone over the top of new seed. If you have broadleaf weeds in a newly seeded area, wait until the seed has germinated, filled in, and grown enough to have been cut at least twice. Use Gordon's Trimec with STIKIT added. Trimec is a little more friendly to baby seedlings.
