Distribution, frequency and molecular basis of clethodim and quizalofop resistance in brome grass (Bromus diandrus)

The identification of target-site-based herbicide resistance in another polyploid weed species provides an opportunity for closer examination of how rapidly resistance evolves in these species under field conditions.

Early silique-shedding wild radish (Raphanus raphanistrum L.) phenotypes persist in a long-term harvest weed seed control managed field in Western Australia

This study introduces a wild radish population collected from Yelbeni in the Western Australian grainbelt that evolved an early silique abscission (shedding) trait to persist despite long-term harvest weed seed control (HWSC) use.

Pyroxasulfone metabolism in resistant Lolium rigidum: is it all down to GST activity?

Resistance to the herbicide pyroxasulfone is slowly but steadily increasing in agricultural weeds. The evolved resistance of one Lolium rigidum population has been attributed to…

Adaptations in wild radish (Raphanus raphanistrum) flowering time, Part 2: Harvest weed seed control shortens flowering by twelve days

This study investigated the effects of repeated HWSC on the evolution of R. raphanistrum flowering dates, using two methods: an adaptation of the SOMER model that included flowering genes (called SOMEF); and a mathematical calculation of the endpoints of flowering date evolution utilizing the relevant life-history equations

Adaptations in wild radish (Raphanus raphanistrum) flowering time, Part 1: Individual-based modeling of a polygenic trait

This study investigated replicating six generations of glasshouse-based flowering date selection in wild radish (Raphanus raphanistrum L.) using an adaptation of the population model SOMER (Spatial Orientated Modelling of Evolutionary Resistance).

Exploring chemical control of 2,4-D-resistant wild radish (Raphanus raphanistrum) with auxin-related compounds

Dr Danica Goggin

The aim of this study was to determine if compounds involved in auxin biosynthesis, transport and signalling are able to synergise with 2,4-D and increase its ability to control 2,4-D-resistant R. raphanistrum populations.
