Yield and phytotoxicity responses of subterranean clover (Trifolium subterraneum L.) sprayed with different herbicides for broadleaf weed control (PDF 6.9 MB)

Research Overview

Teresa investigated the relative herbicide tolerance of subterranean clover at the seedling stage for pasture establishment in New Zealand rain-fed environments. This involved quantification of the field response to herbicides, at different seedling development stages of subterranean clover cultivars. The research confirmed a cultivar⨯herbicide interaction to a range of herbicides, and identified imazethapyr, flumetsulam and bentazone as suitable for use during establishment of subterranean clover based pastures. Longer term effects, such as those on subsequent regeneration and further investigations into effects on development, as well as the apparent brachycalycinum susceptibility is required. Teresa was supervised by Prof. Derrick Moot.

After three years in Australia working as a Research Agronomist for Kalyx Australia Ltd, Teresa returned to New Zealand and is currently working as a Field Development Specialist at UPL Ltd.
