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...

Amira seems to have low crop safety margin for pre-emergent simazine 2 L/ha and post-emergent Lexone , Brodal + Lexone and Brodal + simazine at the label rates... Outlook (dimethenamid-P) - a new pre-emergent herbicide at the label rate caused significant yield loss in Amira... Brodal + Lexone during 2010 and 2011 at both the rates caused significant yield loss in Andromeda, whereas only the higher rate in these two years reduced the yield of Amira...

" Print the page Field studies on glyphosate-resistant barnyard grass by New South Wales Industry & Investment indicated that: the double knock tactic could be effective in controlling resistant biotypes a high rate of glyphosate applied alone to small (2-3 leaf) resistant plants could still provide adequate control... Two pot experiments were conducted in a greenhouse during the 2008/09 and 2009/10 summers to test the efficacy of the double knock tactic (glyphosate followed by paraquat) and to assess the level of control with glyphosate and paraquat alone... Results have shown that the double knock tactic is the only tactic that consistently provided effective control across environments...

Controlled release urea - there is considerable interest in North America with the new controlled release urea (CRU) released by Agrium into the broad acre crop market... The product has a long history, starting originally in the golf course, turf and vegetable market, where long-term N release has great economic value... Further refinement of the coating thickness for field crops has provided products which release their N after 30-60 days post-application...

The experiments are run over 4 years to test the water use efficiency, productivity and riskiness of: (i) a range of continuous cereal systems and the decisions around inputs, timing and agronomy; and (ii) potential break crop systems; across soils of differing potentials... Comparison with the non N-limiting yield potential estimated using the APSIM model of 5.05 t/ha in the swale, 6.06 t/ha in the mid-slope and 5.12 t/ha in the dune, suggests the actual yields are very close to potential yield in the wheat following pasture in the swale but well below for all treatments in the dune and mid-slope (Figure 3)... A build-up of fertility in the swale where fertilizer applications have been uniform across soil types in the past and the swales have under-performed in the dry years has meant that N was not limiting in this soil type and potential yield was attainable in the wheat following pasture where a disease break had been provided...

Varieties listed in the paper are covered by PBR Background This trial forms part of a continued GRDC funded tri-state project (DAV00138, previously DAV00104) involving NSW DPI and SARDI... Recovery from locust grazing was poor, as a result, the emergence and biomass data collected from the affected plots was removed from the analysis... At Culgoa, delaying N until mid-tillering increased grain yields of each variety compared with if it was applied at sowing (P=0.002, LSD 0.26t/ha, c.v. 5.7%) (Figure 5)...
