ANSWERS
The following practices will help maintain overall turfgrass health and
prevent disease development: ---------CORRECT ANSWER-----------------
Select appropriate turfgrass species and varieties, provide adequate
drainage, provide appropriate fertility, avoid compaction, prevent excessive
thatch, use appropriate mowing heights, and improve airflow and light
availability
Provide appropriate turfgrass species and varieties: ---------CORRECT
ANSWER-----------------Use quality seed and plant at recommended seeding
rates. Do not plant grasses that are not adapted to your area
Provide adequate drainage: ---------CORRECT ANSWER-----------------
Excessive moisture can damage roots and affect overall plant health
Provide appropriate fertility: ---------CORRECT ANSWER-----------------Soil
samples. It is essential to find a balance and to fertilize at the appropriate
time of the year. Some diseases thrive when fertility is too low, and some
thrive when fertility is too high.
Avoid compaction: ---------CORRECT ANSWER-----------------Core-aerate
compacted areas. Compacted soil decreases the oxygen supply to roots
and interferes with water movement, reducing plant health.
,Coring: ---------CORRECT ANSWER-----------------A form of cultivation in
which a machine with hollow tines is used to remove soil cores
Prevent excessive thatch: ---------CORRECT ANSWER-----------------Overly
thick thatch is a common problem in turf stands with symptoms that can be
confused with diseases
Use appropriate mowing heights: ---------CORRECT ANSWER-----------------
Mowing to high reduces green tissue, reducing the plants ability to conduct
photosynthesis.
Mow grass frequently so that no more than ______ to ______ of the leaf
area is removed at any one time. ---------CORRECT ANSWER-----------------
1/4, 1/3
Mowing heights for tall fescue or Kentucky bluegrass lawns: ---------
CORRECT ANSWER-----------------2 to 3 1/2 inches is recommended
Mowing heights for zoysiagrass or bermudagrass: ---------CORRECT
ANSWER-----------------1 to 2 inches is recommended
Improve airflow and light availability: ---------CORRECT ANSWER-------------
----Thinning or removal of surrounding shrubs and trees allows sunlight to
penetrate and increases air flow
, The first step in control of turfgrass problems: ---------CORRECT ANSWER-
----------------Accurate diagnosis
To diagnose turfgrass problems follow these steps: ---------CORRECT
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, have knowledge of weather conditions,
determine potential problems with soil structure and fertility, determine the
history of cultural practices at the site, review pesticide management
practices and use reference materials.
Streaks, bands, straight lines or perfect circles are more likely to be caused
by: ---------CORRECT ANSWER-----------------Environmental, non-living
factors
Clumps, patches or random patterns are more likely caused by: ---------
CORRECT ANSWER-----------------A disease or other living organisms
Brown patch: ---------CORRECT ANSWER-----------------Caused by the
fungus Rhizoctonia solani. The most common and important disease of tall
fescue in Kansas. Also problematic on creeping bentgrass and perennial
ryegrass.
Brown patch is: ---------CORRECT ANSWER-----------------A summer
disease, when nighttime temperatures remain above 70 degrees, and
during extended periods of high relative humidity and leaf wetness
