    Description

    Styrofoam container blocks (for example, Styroblock, fig. 1), hereafter "blocks," are a popular system for growing seedlings in greenhouse nurseries. They come in a variety of sizes and can be reused several times. They must be sterilized before reuse because they may harbor pathogens that can cause diseases to seedlings. Potential pathogens, such as Fusarium spp., live on residual organic matter and within the inner cavity walls of blocks. They also may colonize fragments of roots left on containers after the seedlings have been removed.
