dc.description.abstract Manuka oil (MO) is an essential oil derived from Leptospermum scoparium, a member of the Myrtaceae family. The active compound, leptospermone, exhibits pre (PRE) and post-emergent (POST) herbicidal activity. The objective of this project was to explore the PRE and POST efficacy of MO and investigate ways of enhancing its efficacy via tank mixes with adjuvants and/or surfactants or other organic herbicides. Field experiments were conducted on two morphologically different crops, at two different locations, and two planting dates. Efficacy was measured on the basis of visual efficacy and crop injury ratings, weed biomass, and crop yields. Growth room experiments were conducted to analyze the PRE efficacy of MO on green pigweed and large crabgrass. MO was tank mixed with surfactants to create four different herbicide combinations tested under different rain conditions. Weed emergence and weed biomass values were measured to determine efficacy. Results determined that MO had limited efficacy. en_US
