View Full Version : Crab control for new lawn?
05-29-2004, 07:30 PM
Over seeded a terribly thin lawn with 90% fescue 10% blue on April 20th. Limed and applied starter fert 8-18-12. Second rounds get Dimension .15% 21-0-5. Should this lawn get the same or no chemical control? Thanks.

has all the seed germinated?
If so, how mature?
Lawn should be mowed at least 3 times before any chem. controls are used.

Lawn looks a hell of a lot better but the soil is basically red clay with rocks and no sprinkler system. Thanks, I'll remember that 'three cut' rule of thumb.

3 cut rule not necessarrly true, depends on what chemicals being applied!
What control would you apply to a newly seeded lawn??? (except for tupersan and insecticides......)

lesco carries a product called Drive.
Its just what you need.

I am utilizing a permagreen for all of my applications along with a backpack. No spray machine. Which means I'm limited in the use of products, cause I'm not going to backpack large areas. I don't think Drive can be used with low volume sprayers such as the permagreen, am I wrong?

Lesco recommends not applying drive with pg, however acclaim was also not recommended but i get great results with acclaim with my pg.
Drive may need to be mixed in a small bottle first with maybe a gallon of water to make a slurry then put it in the pg. and spray right away.

Isn't it kind of pricey- over $550 per gallon. You just spot spray this? I'm reading that the app rate is between .08 and .90 oz per 1,000, depending upon the growth stage of the grassy weed. Do you average your rate or increase it as the season progresses?
I mainly use Drive to spot treat.....especially curblines.

I've applied Drive using a z-spray, and it worked great. Killed broad leaf weeds and crabgrass. It was applied about eight weeks after seeding or there about. As long as you know how much of a mixture your machine can apply per k sq ft and you mix properly according to label you'll be alright. Just pre mix it in a five gallon bucket or something, because i don't think those pg's have an aggitation system, correct? Drive tends to settle without it, unless pre mixed or well shook up, uh huh, yeah..yeah.. all shook up. ( alittle elvis impersonation)

you base the mix rate on the tiller stage of the target crabgrass. Early stages are one, two tiller. easiest too kill. so on and so forth. or apply medium to low rate then after about two weeks it should be turning purple color and starting to show sighs of death otherwise wait a week after evaluating and re-apply. Some times it takes two apps about three or four to be safe weeks apart for complete crabgrass kill.
