Abstract/Contents:States that within the Poa annua species, "there are true annual types and true perennial types, but to add to the confusion there are many intermediate biotypes that can act as either perennials or annuals, depending on environmental conditions." Describes how to differentiate between annual and perennial types, and why this differentiation is important. Emphasizes the importance of knowing the germination time of annual Poa annua types, as this affects the efficacy of chemical control. Provides data from a North Carolina State University research trial correlating herbicide (Ronstar™) application timings with percent Poa annua control.
