Metribuzin resistance via enhanced metabolism in a multiple herbicide resistant Lolium rigidum population
Most Australian crop farm populations of the grass weed Lolium rigidum are multiple herbicide-resistant. Most resistant populations exhibit target site mutations (e.g. ACCase, ALS), as well as metabolic resistance due to cytochrome P450, catalysed by enhanced rates of herbicide metabolism.
DK‐RIM: Assisting Integrated Management of Lolium multiflorum, Italian Ryegrass
The bio‐economic decision support system, DK‐RIM (Denmark‐Ryegrass Integrated Management), was developed to assist integrated management of L. multiflorum in Danish cropping systems, based on the Australian RIM model. Find out more about this latest publication.
Herbicide Resistance in Plants
Herbicide resistance in weeds is perhaps the most prominent research area within the discipline of weed science today. Incidence, management challenges, and the cost of multiple-resistant weed populations are continually increasing worldwide.
Interactions between crop sequences, weed populations and herbicide use in Western Australian broadacre farms: findings of a six-year survey
Six years of survey data taken from 184 paddocks spanning 14 million ha of land used for crop and pasture production in south-west western Australia were used to assess weed populations, herbicide resistance, integrated weed management (IWM) actions and herbicide use patterns in a dryland agricultural system. Key findings were that weed density within crops was low, with 72% of cropping paddocks containing fewer than 10 grass weeds/m2 at anthesis.
StMADS11 Subfamily Gene PfMADS16 From Polypogon fugax Regulates Early Flowering and Seed Development
The evolution of herbicide resistance in weedy plants leads to various adaptation traits including flowering time and seed germination.
Quizalofop-p-ethyl resistance in Polypogon fugax involves glutathione S-transferases
Asiaminor bluegrass (Polypogon fugax) is one of the main weeds invading Chinese canola fields.
Cinmethylin controls multiple herbicide resistant Lolium rigidum and its wheat selectivity is P450-based
Cinmethylin is a new (old) herbicide being commercialised by BASF that is pre-emergent selective in wheat. Cinmethylin has been shown to be an inhibitor of acyl ACP thioesterase (Campe et al 2018).
Non-target site resistance to PDS-inhibiting herbicides in a wild radish Raphanus raphanistrum population
The paper “Non-target site resistance to PDS-inhibiting herbicides in a wild radish Raphanus raphanistrum population” is the work of AHRI PhD student Huan Lu.
Farming without Glyphosate?
With glyphosate currently under intense scrutiny worldwide from an environmental and health perspective, the paper’s authors contemplate possible scenarios of farming without our most important and popular herbicide.
