Resource can help growers plan for summer spraying.. "Often the most important factor in summer weed control is getting the timing right and using a robust rate of product," Dr Hughes said... Dr Hughes said that with legal pressure on night spraying - due to the presence of surface temperature inversions - South Australian trials tested the control of 'tough weeds' in less than favourable conditions during summer daytime spraying...

Grain growers are urged to have the sprayer ready to go and to spray summer weeds early in order to conserve moisture and increase the yield potential of future crops... A new Grains Research and Development Corporation (GRDC) fact sheet, Summer Fallow Spraying, gives growers and advisers the latest information for spray application and quality resulting from GRDC-funded research... Choose the coarsest spray quality that will provide efficacy with the products selected...

PestFacts South Australia and Western Victoria co-ordinators say that cultural practices have a significant impact on insect populations in field crops and a number of basic steps over the summer and pre-sowing period can help increase the chances of a successful start next season... Summer weeds provide a 'green bridge' for pests such as aphids, mites, snails and diamondback moth to survive on over the hot summer months," said Mr Perry, whose work is supported by growers and the Australian Government through the Grains Research and Development Corporation's (GRDC) investment in the National Invertebrate Pest.. Mr Perry recommends that growers identify paddocks at higher risk of pest pressure and carefully monitor them in the autumn prior to sowing susceptible crops...

Opportunities for growers to broaden weeds approach.. Opportunities exist for grain growers in the southern cropping region to more effectively manage weeds in retained stubble systems, according to new research conducted by the CSIRO and funded by the Grains Research and Development Corporation (GRDC)... Caption: CSIRO Senior Research Scientist (Farming Systems) Dr Rick Llewellyn says a new study has highlighted just how costly weed management has become and where there are opportunities to reduce further cost increases...

Opportunities exist for grain growers in the southern cropping region to more effectively manage weeds in retained stubble systems, according to new research conducted by the CSIRO and funded by the Grains Research and Development Corporation (GRDC)... "The data shows very large differences between regions for practices like harvest weed seed control, crop topping and double knockdown which reflects past differences in the levels of herbicide resistance, but we're now seeing resistance issues becoming much more important in all cropping regions," Dr Llewellyn said...

Feathertop Rhodes grass has a short seed life, so focused control measures over two years could bring the weed in check... Pre-emergent herbicides have a role to play as part of an integrated weed management (IWM) strategy to control feathertop Rhodes grass (FTR), but they are not a standalone solution... While residual herbicides are far from the solution, Mr Daniel says, they are one of the critical tools in controlling a range of weed species, including FTR...

Tighter fallow management gives wheat best chance.. Photo of two men inspecting wheat.. While June was wet, with 100mm of rain recorded, July and August turned dry, and Graham says the crop appeared to "turn blue", or die, because of a lack of moisture...

Research funded by the Grains Research and Development Corporation (GRDC) shows that early control of fallow weeds can lead to significant increases in the levels of stored plant-available water and increased availability of nutrients (especially nitrogen), benefiting crop yield and grain quality... Mr Cameron, who co-authored the GRDC's Summer Fallow Weed Management manual, said soil water saved by killing fallow weeds was often stored deep in the profile and its value is often far higher than that of in-crop rainfall... In the right soil, deep stored soil water can have a water use efficiency of up to 60 kilograms of grain/millimetre of stored water...
