Residual Napropamide and its effect on Western Larch at the Coeur D' Alene Nursery

The success ratio for producing shippable 1-0 western larch (8cm, height and 2mm, caliper) at the Coeur d'Alene Nursery is about 50,.. In an attempt to increase this success ratio, trials were initiated to determine if increased growth could be gained by manipulating the following: 1) the length of time between fumigation and sowing, 2) land use between fumigation and sowing, or 3) use or non use of diphenamid (the mildest preemergence herbicide currently in use at this nursery). This is how the study began, however, there was an unexpected result.
