,When do problems develop with turfgrass? Answer - When the grass is unable
to withstand environmental stress or when good management cannot offset
the effects of environmental stress
What are the steps of diagnosing a problem in turfgrass? (5) Answer -
Determine the kind of grasses involved
Find out why, if possible, the problem occurred
Determine if it can be corrected by management practices, soil modification, or
pesticides
Check to see if a chemical is labeled for both the species and the problem
Recommend good cultural practices that will assist in recovery
What is IPM? Answer - Integrated pest management
An approach to pest management that relies on a combination of common-
sense practices.
Does IPM aim to eliminate all pests? Answer - No
Maintain them at tolerable levels
What are the five steps of IPM? Answer - Education
Monitoring
Prevention
Intervention/Control
Evaluation and Planning
What is an action threshold? Answer - A point at which pest populations or
environmental conditions indicate that pest control action must be taken
,What are the two types of action thresholds? Answer - Economic
Aesthetic
What is an economic action threshold? Answer - Point at which pest
populations or environmental conditions indicate that pest control action must
be taken to prevent an economic loss
What is an aesthetic action threshold? Answer - Point at which pest
populations or environmental conditions indicate that pest control action must
be taken to prevent an aesthetic loss
Example of a highly targeted chemical approach? Answer - Pheromones to
inhibit reproduction in insects
Soil management Answer - Very important in turfgrass management. pH of 6-7
is desired. Need adequate water and oxygen.
Issues with soil management (7) Answer - Excessively wet
Excessively dry
Excessively acidic
Excessively alkaline
Prone to compaction
Impenetrable
Full of debris

Nitrate
What is fertilizer rate expressed as? Answer - lbs of N per 1,000 sq. ft.
How much N should be applied per acre per application? Answer - .5-1 lb
What other element (besides N-K-P) do Colorado lawns need? Answer - Due to
high pH soils here, Iron (Fe) is needed in fertilizer applications
