    Efficacy of two herbicide trials Kingsclear and Lawrencetown
    (University of New Brunswick, 1986) Wren, Kathlen C.; I. Methven
    Weeds often create problems for forest-nursery managers. Weeds can cause direct or indirect reductions in crop growth, quality and survival. Chemical methods of weed control have become an economic alternative to costly manual and mechanical methods. This report examines four pre-emergent herbicides, Napropamide, DCPA, Diphenamid (grass control) and Propazine (broadleaf control) applied in varying rates and combinations at Kingsclear, N.B. and Lawrencetown, N.S. to discover their effectiveness in reducing weed species (broadleaf and grasses) and their tolerance to coniferous crops.
