Catalogue: Broadacre Field Crops DAFF QLD
Publication description: Includes cultivar response tables.. Research in southern Queensland has shown that herbicide tolerance differed among the barley and wheat cultivars grown in the Northern Region... Field experiments were at weed-free sites, where yields were compared between those sprayed with registered herbicides at the recommended and double rates with untreated controls for each cultivar...

Evaluation of the environmental and economic impact of Roundup Ready canola in the Western Australian crop production system James Fisher and D sir e Futures, York, Western Australia, james@desireefutures.net.au Peter Tozer, PRT Consulting, Armidale NSW, prt_consulting@live.com.au.. Overall, the analysis suggests that Roundup Ready canola could be as profitable or more profitable than triazine tolerant canola with a reduced environmental impact and slightly reduced fuel use... Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 176..

For 30 years northern growers and agronomists have relied on Group A herbicides to control wild oats in winter crops; the days are numbered for chemical control as herbicide resistance becomes more widespread across the region.. Many agronomists concerned about the Group A resistance status of wild oats will mix haloxyfop with a 'dim' herbicide [most commonly clethodim]," Mr Cook says. ".. Factor (butroxydim) was not effective as a knockdown for wild oats in chickpeas by itself or when combined with Verdict (haloxyfop); 500 millilitres/ha of Status (clethodim) or mixtures of Verdict (haloxyfop) plus Status proved the most effective combination for knockdown control of wild oats; and..

Well managed weed control plays a vital role in the production of profitable winter crops as weeds can have a significant impact on yield by competing for moisture, nutrients, space and light as well as harbouring diseases... Most growers understand that weed control needs to be considered on a whole-of-farm basis, being particularly conscious of the cropping and chemical rotations where residual herbicides are applied... Residual herbicides are applied to the soil in order to kill weeds by root/shoot uptake and can remain active in the ground for a few weeks up to a few years...

Most growers understand that weed control needs to be considered on a whole-of-farm basis, being particularly conscious of the cropping and chemical rotations where residual herbicides are applied... Before deciding on whether or not to include a herbicide in a control program, growers need a thorough knowledge of the target weed including weed identification, biology and susceptible growth stages; the herbicide including its mode of action (chemical grouping) and application methodology; and site conditions such as soil moisture, surrounding plants, weather conditions and soil characteristics...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, yields were generally greater for those plots with effective control of weeds and lower weed biomass at anthesis (Tables 1 and 2)... In summary, metribuzin shows some promise for use pre-emergent in lupins but is not currently registered at this timing...

The benefits improve crop health and crop competitive ability against weeds and the effectiveness of pre-emergent herbicides... When used as a post-emergent product, little of the herbicide gets to the roots and the control of established weeds is often very poor... benefits arise when the weed is prevented from setting seed as there are no increases to the seedbank and, as a consequence, fewer weeds in the future...
