Water quality characterization of storm and irrigation runoff from a container nursery.

Commercial nurseries grow specialty crops for resale using a variety of methods, including containerized production, utilizing soilless substrates, on a semipervious production surface. These "container" nurseries require daily water application and continuous availability of mineral nutrients. These factors can generate significant nutrients [total nitrogen (TN), and total phosphorus (TP)] and sediment [total suspended solids (TSS)] in runoff, potentially contributing to eutrophication of downstream water bodies.

Host responses and impact on the boxwood blight pathogen, Calonectria pseudonaviculata.

Boxwood leaves are more susceptible to Calonectria pseudonaviculata (Cps) and better suited for Cps reproduction than those of pachysandra and sweet box. Passages through a non-boxwood host may alter Cps ability to sporulate. Calonectria pseudonaviculata (Cps) infects boxwood and its two common companion plants-pachysandra and sweet box.
