Turf Pest Control 3B Kansas
Turfgrass industry in Kansas includes:
home lawns, institutional and industrial grounds, sod production, golf courses, athletic fields
and other recreational turf, parks, roadsides, airports, and cemeteries.
Turf management involves selecting:
the right grass, proper mowing, watering, fertilizing, and controlling thatch.
Geographically, Kansas is
is in the transition zone between the northern cool-season grass range and the southern warm-
season grass range.
Cool season grasses include
bluegrass, tall fescue and ryegrass
Warm season grasses include
bermudagrass, zoysiagrass and buffalograss
The following practices will help maintain overall turfgrass health and prevent disease
development.
Select appropriate turfgass species and varieties, provide adequate drainage, provide
appropriate fertility, avoid compaction, prevent excessive thatch, use appropriate mowing
heights, improve airflow and light availability
The first step in control of turfgrass problems is
accurate diagnosis
To diagnose turfgrass problems follow these steps:
Determine the overall distribution of the problem, identify the affected turfgrass species and
cultivar (if possible), observe symptoms on individual plants, determine weather conditions
before and during disease development, knowledge of weather conditions will help you select
the right disease, determine potential problems with soil structure or fertility, determine the
history of cultural practices at the site, review pesticide management practices, use reference
materials
Common turfgrass diseases in Kansas include:
, brown patch, dollar spot, fairy ring, large patch of zoysiagrass, lef spot and melting out, necrotic
ringspot, pin snow mold/microdochium patch, powdery mildew, plythium foliar blight, rusts,
spring dead spot, slime molds, andsummer patch
Brown Patch
Rhizoctonia salami most common and important disease of tall fescue in Kansas
Brown patch is a
Summer disease
Brown patch is more severe on
Turf grasses under high nitrogen fertilization
Brown patch initially is
Purple-green but quickly fades to light brown
Management of brown patch includes:
Not fertilizing when brown patch is active, avoid seeding rates greater than recommended rates
, do not irrigate in late afternoon or evening.
Dollar spot
Sclerotina hooeocarpa occurs on all turf grasses grown in Kansa
Dollar spot symptoms
Small roughly circular bleached patches. 2-6" diameter in lawn turf grass. 1-2" on putting greens
Management of dollar spot includes
Adequate fertilization program a severe damage is prevalent in nitrogen deficient turf
Fairy ring is caused by:
Fungi in group of basidiomycetes and can occur in all species of turf
Fairy ring fungi grow in the soil or thatch consuming organic matter and affect turf grass growth
In fairy ring after rain or heavy watering
Fungal fruiting structures (mushrooms or puffballs) May appear in the ring area. In addition whit
spongy fungal growth maybe visible in the thatch or soil underneath the ring
Fairy ring symptoms include
