    Get Lesco to get you a poster. I have posted threads titled "on-line training" and stuff with tons of photos.

    get rich,

    you won't find any crabgrass in your lawns in Northern IL this time of year! Soil must be 55 - 60 degree F for 3-6 consecutive days before this annual grass will germinate. Mid May to early June is prime time for crabgrass germination here. If you have a dull green, broad leafed grass mixed with your Kentucky Bluegrass it may be quackgrass (a cool season perrenial) or tall fescue (though tall fescue will be more of a bright shinny green). Quackgrass grows faster than Kentucky Blue and is real noticable when the grass needs mowing.

    Check out the U of I web site. They have some good photos. The Illinois Pesticide Applicator Training Manual, also published by U of I does a good job of discussing the weed grasses. The best way to ID a grass is through the analysis of growth type, presence of stolons and/or rhizomes, blade characteristics, vernation (rolled or folded), auricles, ligules, collars and sheath. Good luck.
