Large Plot Demonstrations in Commercial Nurseries
Four large-plot demonstrations were conducted in commercial nurseries to allow producers to compare available alternatives under their growing conditions.
In 2010-11, two additional demonstrations were conducted in a stonefruit tree nursery and a grapevine nursery. At the stonefruit site, methyl bromide, tarped Telone II, and a co-application of Telone II at 18 inches and chloropicrin at 26 inches (sealed with HDPE) were compared in 0.5 acre plots. At the grapevine nursery, methyl bromide, tarped Telone II, rotovate and roll, and an untarped dual Telone II application were compared in 0.75 acre plots.
