Control of Weeds in the Nursery by Chemicals

A number of new chemicals have come into the market in recent years which have greatly aided nurserymen in the control of weeds. Some, like methyl bromide and allyl alcohol, kill the weed seeds before they germinate. These are applied previous to seeding and require that a week or so elapse after their use before seeding of the tree crop can be safely done. Other chemicals, such as naphtha or mineral spirits, kill the weeds after germination without injuring the coniferous trees. The seed killers have a distinct advantage in that they largely solve the weed problem, for both conifer and broadleaf species during the critical 4 to 6-week-period after treatment. This is especially important for broadleaf species, since mineral spirits applied at dosages heavy enough to kill a high percent of the weeds are generally injurious or fatal to most broadleaves.
