• 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.

• 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.

• 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.

• Silvery Thread Moss

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

• Creeping Woodsorrel

  Creeping woodsorrel is a spreading perennial weed with a reddish-purple color that frequently roots at the nodes.

• Large Crabgrass

  Large crabgrass is a common invader of manicured turf. Large crabgrass has hairs on all surfaces. It can be identified by its light green appearance and swollen, zig-zag nodes.

• Orchardgrass

  Orchardgrass is a competitive perennial grassy weed of cool-season turf. It has a very well developed fibrous root system and can be difficult to remove once established.

• 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).

• Summer Patch

  Summer patch first appears in the warm weather of summer as yellow to bronze-colored, irregular-shaped patches ranging from 6 in. to 3 ft (15.3 cm to 1 m) in diameter.

• Broadleaf Plantain

  Broadleaf plantain is probably the second most common broadleaf weed of turf after dandelion. It is extremely well adapted to most sites including dry or wet conditions, heavy soils and very low mowing heights.

• Prostrate Pigweed

  Prostrate pigweed is a native mat-forming summer annual weed that invades thin, damaged or under-fertilized lawns. It is common in areas with disturbed soils or neglected areas. Prostrate pigweed lacks the hairs common to redroot pigweed and has smooth leaves.

• Yellow Patch

  Yellow patch, also known as cool season brown-patch, is a Rhizoctonia pathogen similar to that of brown patch.

• Goosegrass

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

• Corn Speedwell

  Corn speedwell is an upright, clumping winter annual that produces small purple flowers in the spring. The lower, non-flower, portion of the plant has leaves that are round-to-oblong with rounded teeth on the margin in an opposite arrangement.

• 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.

• 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.

• Red Thread

  Red thread is a disease of slow growing turf. Red thread is easily recognized by the red to coral-pink fungal strands (stromata) produced on leaf blades and sheaths.

• Dollar Spot

  Dollar spot is characterized by round, bleached-out or straw-colored spots, ranging from the size of a quarter to the size of a silver dollar. Spots appear as sunken areas in the turf, especially low mown turfgrass.
