• Buckhorn Plantain

• Yellow Hawkweed

  Yellow hawkweed is a creeping perennial of low maintenance turf, roadsides and native areas. It can be an indicator of low soil fertility or slightly acidic soils. Hawkweed spreads by stolons and rhizomes creating colonies that form patches.

• Red Sorrel

  Red sorrel is a perennial weed of low-maintenance sites characterized by dry, infertile and often low pH soils. Red sorrel will survive at neutral pH but is usually not as prevalent because the turf will be more competitive under these conditions.

• Melting Out

  Symptoms of melting-out resemble leaf spot symptoms and these two diseases are often grouped together. Melting out however is a cool-weather disease where leaf spot is a warm-weather disease.

• Goosegrass

  Goosegrass is a warm season summer annual grassy weed that predominates in exposed, trafficked conditions.

• Necrotic Ring Spot

  The pathogen attacks root systems in the spring and fall, and in the summer, infected plants begin to wilt in patches.

• Black Medic

  Black medic is a low-growing creeping weed that is well adapted to many lawn situations. In particular, black medic can be an indication of low soil nitrogen. It is most common to find medic in full sun , low maintenance situations. Black medic and white clover grow in similar situation and are often found growing together.

• Smooth Crabgrass

  Smooth crabgrass is the most common summer annual grass problem in managed turf.

• Wild Carrot

  One of the two most common weeds of Midwestern roadsides. Wild carrot (Queen Anne's-lace) is a biennial that forms a carrot-like taproot that allows it to survive the harsh, gravely, nutrient deficient conditions that it thrives in.

• Nimblewill

  Nimblewill is a warm-season turfgrass that will infest cool-season turf. It has excellent winter hardiness which allows it to establish and compete.

• Fairy Ring

  Fairy rings tend to grow in circle shaped patterns through the organic matter in the soil, mat, and thatch, first appearing as dark green circular rings or arcs in the turf.

• Common Mallow

  Common mallow most often establishes along culverts, fencelines and near foundations. Common mallow forms a clump whorled branches that do not root where they touch the ground.

• Creeping Bentgrass

  Creeping bentgrass is a spreading cool-season perennial grass that is commonly used for golf course greens, tees and fairways. Like other grasses, bentgrass can be considered a weed when it is present in another species.

• Dandelion

  Common dandelion is a simple perennial (no branching) with a basal rosette that has deeply lobed leaves that generally point back towards the center of the rosette. Probably the most common weed in maintained turf.

• Powdery Mildew

  Turf affected by the disease have a grayish white cast, with initial symptoms appearing as white patches on the leaf blade.

• White Clover

  White clover is one of the most common weeds of turfgrass. It is frequently included on lists of difficult-to-control weeds. White clover, as with all legumes, has the ability to survive under low soil nitrogen conditions. It can be identified by the three leaflets attached to one petiole.

• Yarrow, Common

  Common yarrow is considered a desirable herbaceous perennial by many gardeners and is sold in its cultivated form at most greenhouses.

• Microdochium Patch

  This is the most important disease in areas with extended periods of cool wet weather. Symptoms appear as reddish brown to copper-colored spots in the turf.
