weed control

Over the past two decades, feathertop rhodes grass has gone from being a minor cropping weed to a major problem for northern - and now some southern - growers... The only way to control fTr effectively is to use an integrated weed management (iWM) approach... The efficacy of herbicides against fTr drops rapidly when plants are larger than the early tillering stage or are moisture stressed, so spray as soon as possible after rain for best results...

Professor Powles said that under this technology, which is in the early stages of development, a mirror copy is made of a weed's DNA in which targeted genes can be turned on or off... "Whether or not BioDirect@" as a herbicide will come to commercial fruition is very difficult for me to judge, but I hope fervently that it does because we need all the tools we can muster to battle weeds and herbicide resistance," he said... Professor Powles said there was no doubt that the evolution of herbicide resistant weeds was a major threat to global food production, which needed to be able to feed nine billion people in coming decades...

At a Merredin Research Station field day, DAFWA researchers Dr Abul Hashem (left) and Mohammad Amjad explain the effects of lime on reducing annual ryegrass in a wheat/lupin/barley/barley rotation, four years after application of limesand... Western Australian research is showing that lime application not only helps to overcome soil constraints, but can also diminish weed burdens in low pH wheatbelt soils... The trials found the use of lime to achieve (even small) increases in pH significantly reduced the density of annual ryegrass, barley grass and wild radish in that timeframe...

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...

Crop weeds can most effectively be managed by integrating chemical and non-chemical control... Pre-plant application - herbicide is applied before the crop is planted and before rain allows weeds to germinate... Post-plant, pre-emergent application - herbicide may be applied to the seedbed after planting the crop, preferably before weeds and crop have germinated...

Increasing herbicide resistance in weeds, particularly to glyphosate, has had a significant impact on Western Australian grain growers in recent years, and it is now posing a threat to the northern grains industry.. "Northern growers need to learn from the west's weed-management failures and consider making important attitude and management changes," Mr Fosbery says... Speaking at the GRDC Grains Research Updates earlier this year, Mr Fosbery urged growers to avoid relying on single-hit control measures and to learn more about weeds and different ways they can be controlled...
