The work showed that Touchdown Broadacre Tm (TD- BA) offered ~96% control but another formulation of a Group M herbicide at comparable use rates only controlled 10% at 52 days after application (DAA)... A group M herbicide @ 2lt/ha followed by a double knock of Sprayseed Tm offered moderate improvement in control (61% control @ 52 DAA)... The summary of the results of this trial is shown in Graph 1 below...

Suitable and safe herbicides are limited in pulses, especially for the post emergent control of broadleaf weeds, with many registered herbicides only having a narrow safety margin... The project will use ethyl methane sulfonate (EMS) mutagenesis techniques, as used in pasture legumes, lentils and lupins previously in Australia, on PBA Flash lentil and Nura faba bean to develop lines with tolerance to at least one new novel herbicide, in each crop, offering increased weed control options... The spray chamber method while effective for PE is slow, expensive and is not ideally suited to post sowing pre-emergent treatments other methods are being explored to meet the criteria...

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...

Time is right to fight flaxleaf fleabane.. "When treated young, at one month or less, susceptible flaxleaf fleabane plants in fallow can be controlled with glyphosate quite often a glyphosate mixture or double knock is required for optimal control," Dr Widderick said... For rosette control in fallows Dr Widderick said the most consistently effective treatments were double-knocks (sequential application), particularly with glyphosate and Tordon 75-D followed seven days later with Spray...

Overall, 64-70% of the cultivar x herbicide combinations resulted in no significant yield losses at both recommended and double rates... 9-10% of the cultivar x herbicide combinations had significant yield losses at the recommended rate in one or more trials... In summary, 70% of the wheat x herbicide combinations and 64% of the barley x herbicide combinations had no significant yield losses at both the recommended and double rates...

The research highlighted that Northern Region (NR) wheat and barley varieties differed considerably in their sensitivity to these herbicides... The information generated from this project has the potential to save approximately 20 per cent crop income, as indicated by the 3 to 38 per cent significant yield losses measured for certain cultivars from registered herbicides at the recommended rates... The results from this and the previous projects have identified those cultivar x herbicide combinations that may cause significant yield losses at the herbicide recommended rate and timing...
