The Use of Dazomet for Partial Sterilization of Forest Nursery Soils
Forestry Commission, Northern Research Station
Experiments in Scottish and English forest nurseries compared dazomet with formalin as partial soil sterilants for conifer seedbeds. In most cases, the more easily handled dazomet not only proved to be an acceptable alternative to formalin for improving seedling growth and yield but also gave excellent weed control. Results from a large-scale trial in a Scottish nursery confirmed these findings and showed that the higher chemical cost of dazomet sterilization could be offset by reduced weeding costs. Dazomet treatment recommendations have been derived from the trials.
