Wild radish warrants radical response.. Successful long-term management of wild radish involves driving down its seedbank to very low levels and doing 'whatever it takes to stop a weed seed blow-out'... Many Western Australian growers have only one effective herbicide mode of action remaining that they can use to control wild radish - one of the most widespread and competitive weeds of grain cropping...

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...

While winter conditions have now arrived in the north, an unusually warm June prompted a rapid growth response in wheat crops and weeds, forcing growers to implement weed control strategies early and effectively to avoid problems as the season progresses... Planning a coordinated and effective in-crop strategy to control weeds, particularly problem grassy weeds like wild oats, will help growers maximise crop yields while reducing the likelihood of developing a herbicide resistance problem on-farm... In cases where resistance status of weed outbreaks is known or there have been problems in the past with the efficacy of Group A chemicals, growers should consider rotating to a 'den' Group B herbicide or a combination of Groups A and B herbicides, with the aim of using only one Group B chemical within three years...

The agronomist from Dubbo, New South Wales, says two years of survey data show herbicide resistance is increasing at an alarming rate across the central western NSW cropping belt and growers need to change tactics urgently to develop effective, long-term weed-management strategies... "In the GOA surveys both ryegrass and black oats demonstrated a high incidence of resistance, with 100 per cent of the ryegrass and 86 per cent of black oats showing resistance to at least one herbicide," Mr Street says... Before growers and agronomists decide on a course of action, Mr Street says it is critical they start testing survivor weed samples so they can map the resistance status of individual farms and paddocks as part of the process to develop effective long-term strategy for the management of hard-to-kill weeds...
