The nursery projects in the Pacific Area-wide Program for Integrated Methyl Bromide Alternatives differ from the production projects in that the end products are “plants for transplanting”. Highly specialized and intensive systems have evolved to produce the planting stock needed to support the field-scale planting of field, orchard, and vineyard crops as well as forestry systems. In most cases, the nursery stock is produced at very high planting densities by highly skilled horticulturalists and the harvested stock is utilized on hundreds or thousands more production acres.
Although some nursery stock can be produced in containers or soil-less media, many nursery producers utilize in-ground production systems due to scale or economic limitations. In-ground nursery operations have historically relied on preplant fumigation to provide broad spectrum pest control and, in some cases, to meet stringent phytosanitary requirements.
The nursery projects, all targeting in-ground operations, included: :
- Cut flowers and ornamentals
- Forest nurseries
- Perennial crop nurseries
- Raspberry nurseries
- Sweet potato hotbeds
