Turf Pest Control 3B Kansas
Turfgrass industry in Kansas includes:
home lawns, ins tu onal and industrial grounds, sod produc on, golf courses, athle c fields
and other recrea onal turf, parks, roadsides, airports, and cemeteries.
Turf management involves selec ng:
the right grass, proper mowing, watering, fer lizing, and controlling thatch.

is in the transi on 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 prac ces will help maintain overall turfgrass health and prevent disease
development.
Select appropriate turfgass species and varie es, provide adequate drainage, provide
appropriate fer lity, avoid compac on, 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 distribu on of the problem, iden fy the affected turfgrass species and
cul var (if possible), observe symptoms on individual plants, determine weather condi ons
before and during disease development, knowledge of weather condi ons will help you select
the right disease, determine poten al problems with soil structure or fer lity, determine the
history of cultural prac ces at the site, review pes cide management prac ces, use reference
materials
Common turfgrass diseases in Kansas include:
, brown patch, dollar spot, fairy ring, large patch of zoysiagrass, lef spot and mel ng out, necro c
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 fer liza on
Brown patch ini ally is
Purple-green but quickly fades to light brown
Management of brown patch includes:
Not fer lizing when brown patch is ac ve, avoid seeding rates greater than recommended rates
, do not irrigate in late a)ernoon or evening.

Adequate fer liza on 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 maFer and affect turf grass growth
In fairy ring a)er rain or heavy watering
Fungal frui ng structures (mushrooms or puHalls) May appear in the ring area. In addi on whit
spongy fungal growth maybe visible in the thatch or soil underneath the ring
Fairy ring symptoms include
