Herbicide sequences target radish control.. Trials in Western Australia's northern agricultural region in 2012 showed that older herbicides are still effective against wild radish and continue to play an important role in controlling this costly weed... "Given we set out to target really tough populations of radish, this result was a surprise and should give growers and agronomists a lot more confidence in continuing to use some of the older, cheaper herbicide chemistry for a least one spray in a two-spray strategy," he says...

Two sprays tackle stacked resistant radish.. Treating wild radish ( Raphanus raphanistrum L. ) early in the growing season in the northern wheatbelt as part of a two-spray strategy - using robust herbicide rates and excellent application - can boost wheat yields by 0.5-1 tonne/hectare... His results backed-up the 2012 RCSN project findings that - for such resistant populations - the best practice management was early spraying, followed by a quick and timely second spray using robust herbicide rates...

Wild radish causes severe crop yield losses or forced non-crop phases if uncontrolled and has developed multiple herbicide group resistance, most recently to glyphosate... Research conducted in the Northern Agricultural Region and supported by the Grains Research and Development Corporation (GRDC) Regional Cropping Solutions Networks (RCSNs) initiative has identified best practice herbicide management for wild radish with multiple herbicide resistance... "The trials found that best practice revolved around early spraying of small plants (about the size of the top of a beer can) with excellent application (including adequate water rates) - followed by a quick and timely second spray of a herbicide with a different mode of application," Mr Newman said...

Research reveals keys to wild radish control.. "Given growers need a diverse range of herbicide options for wild radish control, two sprays are best," he said... Mr Newman said there were a number of effective combinations in the trials that used older herbicides as part of the two-spray strategy, and would pave the way for farmers to reduce reliance on newer chemistries...

Efforts to eradicate wild radish have intensified on the property of Simon and Dahnie Smart at Chapman Valley, near Geraldton, as costs to control this scourge escalate to about $50 per hectare... Shaun Earl manages the Smarts' farm and says the family is closely monitoring wild radish resistance and implementing a range of chemical and non-chemical strategies to combat this problem... "We know there is partial radish resistance on this property to all chemicals but we don't have plants with full resistance," he says...
