herbicide cost

Categorised under:

Catalogue: GRDC Updates
Growers that have the weed seed bank under control will save herbicide costs; be able to use diverse tactics that would otherwise be cost prohibitive; and, by reducing the frequency of herbicide applications, will delay the onset of herbicide resistance... With any discussion on managing resistance we need to start with the basics and understand why we have the problem in the first place... Registration of high application rates by this technique may allow the control of resistant weeds that have survived a preceding application of a different mode of action...

The results of the experiments have given Jeff the confidence to realise that he does have a viable, cost-effective alternative knockdown herbicide to glyphosate... Double knockdown (T 2.2b, page 128) Weather permitting, a double knockdown is implemented on resistant ryegrass paddocks prior to sowing using two non-selective herbicides (glyphosate followed by paraquat + diquat or paraquat, the choice being dependent upon the range of weeds present)... Helpful advice The Grays still enjoy the challenges and can see that they have made enough progress to feel they are being successful in managing a serious annual ryegrass problem...

With 'single knocks', 'double knocks' and residual herbicides, growers in the northern region are successfully fighting back against fleabane.. Fleabane is a wind-borne, surface-germinating weed that thrives in areas of low competition and which proliferated in the northern region as growers moved towards reduced and no-till farming... Fleabane proliferated in the northern region but has spread south and west as more growers adopt no-till and reduced-till farming...

Untreated: no fungicide SD: seed dressing applied just prior to sowing V early: foliar applied at time of herbicide application: 2 to 3 tillers Early: foliar applied timed to protect the flag leaf: flag leaf just visible Late: foliar applied after flag leaf fully emerged: early heading SD+T1+T2+T3: all the above treatments Seed dressing (SD): fluquinconazole 167 g /L: 4.5 L / tonne seed Foliar sprays: tebuconazole 430 g / L: 290 mL / ha.. A foliar spray timed to protect the flag leaf produced a greater yield benefit...

Brome grass is becoming an increasing problem... Both species are commonly referred to as ripgut brome often resulting in confusion over correct identification... Recent research has shown that seed collected from field populations of both species are showing longer dormancy which appears to be under hormonal control within the seed embryo...

" Genetically improving wheat's ability to outcompete weeds.. The cost of weeds to Australian agriculture is estimated at an annual $4 billion through crop yield loss and seed contamination... The aims of the project are to develop: (1) a robust and repeatable screening methodology for improved weed competitiveness for use in commercial breeding programs; (2) understanding of those morphological/physiological factors contributing to improved competitiveness; and (3) development and release of elite spring wheat germplasm containing traits with improved competitiveness for use as parents in breeding of new weed-competitive varieties...
