brown

brown patch is active, avoid seeding rates greater than recommended rates ,
do not irrigate in late afternoon or evening.

grown in Kansa
16.Dollar spot symptoms - ANSWER Small roughly circular bleached patches.
2-6" diameter in lawn turf grass. 1-2" on putting greens

program a severe damage is prevalent in nitrogen deficient turf
18.Fairy ring is caused by: - ANSWER Fungi in group of basidiomycetes and
can occur in all species of turf
19.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
20.Fairy ring symptoms include - ANSWER Three categories.
21.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
22.Type 2 Fairy ring - ANSWER Display a ring of lunch dark green turf and
May or may not have fungal fruiting structures
23.Type 3 fairy ring - ANSWER Develop a ring of fruiting bodies with no
visible effect on the turf grass. May range in diameter from a few inches to
50 feet or more and they can expand overtime.
, 24.Fairy ring management includes - ANSWER No management needed as
they symptoms are temporary .
25.Leaf spot and melting out is caused by - ANSWER Several different fungi.
Most common on Kentucky blue grass and tall fescue
26.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.
27.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.
28.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
29.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.
30.Moss - ANSWER Like algae, moss occurs where turfgrass has been thinned
due to one or more site or environmental factors.
31.Animal Urine injury - ANSWER Injury from dog or other animal urine may
resemble brown patch or dollar spot.
