Exam Questions Fully Solved .
Turfgrass industry in Kansas includes: - Answer 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: - Answer the right grass, proper mowing, watering,
fertilizing, and controlling thatch.
Geographically, Kansas is - Answer is in the transition zone between the northern cool-season
grass range and the southern warm-season grass range.
Cool season grasses include - Answer bluegrass, tall fescue and ryegrass
Warm season grasses include - Answer bermudagrass, zoysiagrass and buffalograss
The following practices will help maintain overall turfgrass health and prevent disease
development. - Answer 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 - Answer accurate diagnosis
To diagnose turfgrass problems follow these steps: - Answer 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: - Answer 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 is more severe on - Answer Turf grasses under high nitrogen fertilization
Brown patch initially is - Answer Purple-green but quickly fades to light brown
Management of brown patch includes: - Answer Not fertilizing when brown patch is active,
avoid seeding rates greater than recommended rates , do not irrigate in late afternoon or
evening.
Dollar spot - Answer Sclerotina hooeocarpa occurs on all turf grasses grown in Kansa
Dollar spot symptoms - Answer Small roughly circular bleached patches. 2-6" diameter in lawn
turf grass. 1-2" on putting greens
Management of dollar spot includes - Answer Adequate fertilization program a severe damage
is prevalent in nitrogen deficient turf
Fairy ring is caused by: - Answer 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
- Answer
In fairy ring after rain or heavy watering - Answer 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 - Answer Three categories.
Type 1 fairy rings - Answer Include turf death and are most common on sand based putting
greens. Has been associated with high salt content and hydrophobic conditions in the soil
caused by fungi
Type 2 Fairy ring - Answer Display a ring of lunch dark green turf and May or may not have
fungal fruiting structures
, Fairy ring management includes - Answer No management needed as they symptoms are
temporary .
Leaf spot and melting out is caused by - Answer Several different fungi. Most common on
Kentucky blue grass and tall fescue
Nutrient Deficiency - Answer Areas or all of the turf may become yellowed and stunted.
Chlorosis (yellowing) is usually caused by nitrogen deficiency or iron deficiency.
Buried Debris - Answer A thin layer of soil over buried rocks, lumber, bricks, plaster, or
concrete dries out rapidly in dry summer weather and may resemble disease.
compacted areas - Answer Thin turf or bare spots appear in heavily used areas. Waterlogged
and heavy-textured (clay) soils become compacted especially in areas with frequent foot or
vehicle traffic
Algae - Answer A green to blackish algae slime may form on bare soil or thinned turf in low,
wet, shaded or heavily used and compacted areas. The slimy mass of algae dries to form a thin,
black crust that later cracks and peels.
Moss - Answer Like algae, moss occurs where turfgrass has been thinned due to one or more
site or environmental factors.
Animal Urine injury - Answer Injury from dog or other animal urine may resemble brown
patch or dollar spot.
Thatch - Answer Thatch is a tightly intermingled layer of decomposing stems and roots that
develops between green vegetation and the soil surface.
To plan a good weed control program, you must: - Answer identify the desirable turfgrass,
•
identify the existing weeds, and
•
combine pest control with good management practices.
