• Slime Mold

  Slime molds are non-pathogenic fungi that occasionally dwell on many different turfgrass species.

• Common Purslane

  Common purslane is a mat-forming summer annual that thrives in all soil types. Common purslane has multi-branched red stems with thick fleshy leaves that cluster at the end of the branches.

• Common Milkweed

  Milkweed is easily identified by its upright growth habit and large (entire) leaves. All plant parts will exude a milky white latex when broken.

• 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.

• Yellow Woodsorrel

  Yellow woodsorrel is a common summer annual in cool-season turf. Yellow woodsorrel is one of the latest germinating summer annual weeds. Often, infestations of oxalis can be associated with spring-timed broadleaf weed control applications.

• Bull Thistle

  Bull thistle is a clumping biennial that forms a thick taproot in its first growing season. The leaves of bull thistle are covered with 'soft' hairs and needle-like spines on the margin.

• Curly Dock

  Curly dock is a long taprooted simple (non-branching) perennial that grows in a rosette. The 6-8" long elliptical or lance-shaped leaves of curly dock have entire but wavy margins (not toothed). The youngest leaves smooth margins that get progressively more rippled as the leaf matures. The appearance of the mature leaves resembles leaf lettuce (very curly).

• Gray Leaf Spot

  Gray leaf spot is considered a problem on primarily perennial ryegrass and St. Augustinegrass. The disease first appears as tiny brown spots that enlarge and become oval or elongated.

• Yellow Nutsedge

  Yellow nutsedge is a persistent perennial weed of poorly drained soils. Yellow nutsedge is grass-like in its appearance with parallel leaf veination. The stem of nutsedge is triangular with leaves coming off each corner (three-ranked).

• Necrotic Ring Spot

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

• 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.

• Giant Foxtail

  Giant foxtail is a larger plant than green or yellow foxtail. Giant foxtail will not tolerate mowing and is rarely found in mowed turf areas. It is most commonly a weed of cultivated crops.

• 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.

• Wild Violet

  Wild violet is a low-growing clumping (simple) perennial with a dense, fibrous root system and heart-shaped leaves that often cup toward the petiole to form a funnel shape. Wild violet is often considered difficult-to-control due to its aggressive growth, waxy leaves and resistance to most common herbicides.

• Field Horsetail

  Field horsetail is most often a weed of landscape beds and low-lying areas. Horsetail can survive in turf, but often will not persist with routine mowing.

• Chicory

  Chicory is a simple (unbranched) perennial with a jagged fleshy taproot. The coarsely-toothed basal leaves are 6-8" long and form a rosette.

• Pythium Blight

  Pythium first appears as circular reddish brown spots in the turf, ranging in diameter from 1 to 6 in. In the morning dew, infected leaf blades appear water soaked and dark and may feel slimy.

• Crown Rot Anthracnose

  Anthracnose can occur as both a foliar infecting and crown infecting disease.

• Silvery Thread Moss

  Silvery thread moss is the most common species found in turfgrass, usually appearing on putting greens and in shaded back yards.

• Yellow Rocket

  Yellow rocket is a rosette-forming winter annual that is usually associated with bare, disturbed soil or new establishments (prefers nutrient-rich, medium-textured soils).
