Frost puts freeze on effectiveness of ryegrass herbicide.. "Ideally, spray small ryegrass plants under warmer and frost-free periods for the best results with clethodim on ryegrass," said Dr Gill when addressing a GRDC Grains Research Update in Campbell Town, Tasmania, on the topic of controlling herbicide-resistant annual ryegrass in canola crops... We want the ryegrass to be actively growing and stress-free for clethodim to do the best job, so growers need to watch the weather forecasts closely to determine the best time to spray," Dr Gill said...

In summary, it could be argued that none of the currently available preemergence herbicides have the required stability in efficacy to become viable alternatives to postemergence group A or imidazolinone herbicides... Overall, 2012 seasonal conditions tended to favour early and mid flowering and maturing varieties...

1.1) Fitness costs of herbicide resistance in a multiple-resistant L. rigidum biotype The L. rigidum biotype SLR31 exhibits multiple herbicide resistance due to the possession of two mechanisms; an insensitive ACCase target site and enhanced metabolic activity of the detoxifying P450 enzyme family... It is essential that alternate herbicide chemistries are evaluated for their potential to control annual ryegrass and wild radish... As it is likely that the capacity of harvesters will continue to increase, a logical approach to developing an effective weed seed # refer to 'Report disclaimer' grinding system was to focus on processing only the weed seed containing fraction of the chaff...

Frost in the few days after clethodim application reduces activity of the herbicide on annual ryegrass.. The best management for clethodim resistant annual ryegrass in break crops is a pre-emergent herbicide followed by a mixture of clethodim plus butroxydim on small ryegrass plants.. Surveys across South Australia and Victoria from 2005 show an increase in incidence of resistance to herbicides in annual ryegrass populations (Table 1)...

University of Adelaide research associate Dr Sam Kleemann has conducted trials on the Koch family's property on the Victorian side of the border at Frances, SA, looking at herbicide strategies to control clethodim-resistant ryegrass... The research, by the University of Adelaide along with the MacKillop Farm Management Group, indicates that using an appropriate herbicide regime involving Roundup and triazine-tolerant (RT) canola (Table 1) followed by wheat in the second year improved control over resistant ryegrass by up to 70 per cent compared with standard grower practice strategies (first row in Table 1 - simazine incorporated by sowing (IBS) followed by atrazine and clethodim post-emergence)... University of Adelaide researcher Dr Sam Kleemann says it was unsurprising that the standard grower treatment during the canola phase gave poor ryegrass control...
