The cold months of winter are the ideal time to clean empty grain silos to eradicate insects harbouring in grain residues, according to grain storage specialist Chris Newman... "Now, while it is cold, is an excellent time to remove grain residues - which provide a source of food for insects - from silos and surrounding areas," he said...

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...

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...

Growers using integrated weed management (IWM), including the strategic use of herbicides, can control ryegrass, despite high levels of resistance, researchers from the WA Department of Agriculture at Geraldton have found... "Growers who added IWM techniques such as a pasture phase, crop-topping and windrow burning (or chaff cart) generally managed to erode a ryegrass seed bank, reducing weed competition with the crop and reducing the selection pressure placed on trifluralin and other herbicides... Mr Newman says results give growers, researchers and agribusiness confidence that IWM works in real-life situations. "..

Twelve years of monitoring 30 commercial cropping paddocks containing herbicide-resistant annual ryegrass ( Lolium rigidum ) has convinced Australian Herbicide Resistance Initiative communications manager Peter Newman that an integrated weed management approach is the only way to get on top of herbicide resistance... "Put simply, growers should use a combination of herbicide and non-herbicide weed control for long-term success," he said... Mr Newman said that when growers focused on holistically managing herbicide-resistant annual ryegrass, they achieved a 98 per cent reduction in ryegrass numbers over 12 years...

High nitrogen atmosphere to control pests in storage.. By controlling the atmosphere in grain storage, growers can potentially capitalise on the benefits of using a non-insecticide alternative to phosphine, according to Murdoch University's laboratory business and industry liaison manager, James Newman... "I think the idea of using nitrogen for storing grain on-farm will gain momentum over the next few years," he said...

Weeds compete against crops for valuable moisture, light and nutrients, but growers can take steps in coming weeks to help their wheat crops fight back and stop the weeds winning... Mr Newman said the seed size of wheat varieties varied considerably and growers should take this into account when calculating seeding rates and plant density... "In the eighth year of using this practice, these growers had no ryegrass in their focus paddocks and have averaged fewer than 1.5 ryegrass plants per square metre ever since," Mr Newman said...
