Kentucky bluegrass |
- one of the three "cool-season"
turfgrasses
commonly
grown in colder parts of the
United States. It spreads
by rhizomes and results in a "carpet" looking lawn.
Kentucky bluegrass is
commonly combined with

cool-season grass seed mixtures for the home landscape
in temperate regions. |

Koch’s postulates |
- a technique for determining if a specific organism is
causing a disease. It consists of isolating the

plant with the pathogen, observing the same symptoms as
on the original infected plant and then re-isolating the
pathogen from the second plant. |
