Glyphosate Resistant Weeds - Beat Them Before They Beat You, Sally Peltzer Jan 2014

Glyphosate Resistant Weeds - Beat Them Before They Beat You, Sally Peltzer

Grain and other field crops published reports

Herbicide resistance develops if the weeds exist in the population and set fertile seed. Being vigilant, keeping weed populations low and stopping seed set is the best way to prevent glyphosate resistance development:

  • know the herbicide use history of each paddock. If glyphosate has been the dominant knockdown and spray-topping product used, it's time to change
  • conduct herbicide resistance testing to determine what herbicides are effective on key weeds
  • aim for maximum control
  • establish a more diverse rotation to increase the number of control tactics available
  • use non-herbicide control tactics at every opportunity
  • always monitor the success of each control …


Report Card On Sustainable Natural Resource Use In Agriculture : Status And Trend In The Agricultural Areas Of The South-West Of Western Australia, Department Of Agriculture And Food, Western Australia Sep 2013

Report Card On Sustainable Natural Resource Use In Agriculture : Status And Trend In The Agricultural Areas Of The South-West Of Western Australia, Department Of Agriculture And Food, Western Australia

Books & book chapters

This report card summarises our current knowledge of the status and trend in the natural resource base in the agricultural areas of the south-west of Western Australia (WA) and provides a discussion of the implications for agricultural industries.

The condition of our natural resources is a complex interaction of numerous processes. In simple terms however, the performance of the land is driven by three primary factors: climate, land characteristics and land management. The first two factors are largely out of the control of land managers, and in a drying and variable climate, land management practices need to be able to …

Irrigated Agricultural Development in the North

The Western Australian Government is developing additional land for irrigated agriculture adjacent to the existing Ord River Irrigation Area (Ord Stage 1), in the Kimberley region of Western Australia. The expansion, referred to as greater Ord Stage 2 has identified land along the lower Ord (Packsaddle, West Bank, Carlton Station and Mantinea), the Cockatoo Sands, as well as the Weaber, Keep River and Knox Creek Plains as suitable for development. The current development of the Weaber and Knox Creek Plains, referred to as the M2 Supply Area, will increase the current area under irrigation from 14,000 to potentially 30, 500 …


Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey Aug 2013

Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey

Bulletins 4000 -

Applying agricultural lime is the most economical way of ameliorating low soil pH in broadscale agriculture in Western Australia (WA). In WA, agricultural lime is usually limesand from coastal sand dunes, crushed limestone from coastal deposits or crushed dolomitic lime (usually marketed as dolomite) from old lake and inland drainage systems. Other sources are Cretaceous chalk and lake bed marls.

WA agriculture is well serviced by lime suppliers, although the quality of lime varies markedly around the State, and cost does not always reflect quality as measured by neutralising value and fineness. Neutralising value and particle size distribution (fineness) are …


West Coast Demersal Scalefish Allocation Report., Integrated Fisheries Allocation Advisory Committee. Jul 2013

West Coast Demersal Scalefish Allocation Report., Integrated Fisheries Allocation Advisory Committee.

Fisheries Management Papers

Integrated Fisheries Management (IFM) is an initiative aimed at addressing the issue of how fish resources in WesternAustralia can be best shared between competing users within the broad context of “Ecologically Sustainable Development”, or ESD, so that they can be managed on a sustainable basis.

The Minister for Fisheries established the Integrated Fisheries Management Allocation Advisory Committee (the Allocation Committee), under Section 42 of the Fish Resources Management Act 1994 (FRMA), in 2004 to investigate IFM resource allocation issues and make recommendations to him on optimal resource use.


Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia. Jul 2013

Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia.

Fisheries Management Papers

The practice of releasing hatchery-reared fish into existing populations to augment fishing (stock enhancement) or restore depleted spawning biomass (restocking) has occurred around the world for decades with varying degrees of success. The underpinning concept is to produce and release fish into wild populations to increase their abundance, catch rates and/or fishery yields

If restocking and stock enhancement activities are to be successful, they should have clear objectives and be well planned and targeted at situations where there is a reasonable expectation of having a beneficial effect.

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia Oct 2012

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia

Fisheries Management Papers

The Department of Fisheries (Department) is proposing a new simplified management approach which focuses on fishing as the core criteria in the new licensing framework. Given the low level of impact of aquatic eco-tours and shore-based fishing, consideration is being given to removing the need for these activities to be formally licensed. The Department is of the view that these activities can be adequately managed by regulations that have broader application across the community.

The current management, licensing and fee structures are complex and provide limited business flexibility. A simplified management approach will also improve the Department’s capacity to monitor …

The purpose of this report has been to investigate potential reallocation mechanisms for the transfer and/or adjustment of catch shares between sectors and the requirements to allow for their implementation, with particular reference to their application in the Western and South Australian rock lobster fisheries. While the report focuses on the commercial and recreational sectors of these fisheries, potentially all non-commercial fishing sectors could be included under a given mechanism in the same manner as that outlined for the recreational sector, subject to the appropriateness of allowing the sector’s allocation to be transferable


Are Western Australian Waters The Least Productive Waters For Finfish Across Two Oceans? A Review With A Focus On Finfish Resources In The Kimberley Region And North Coast Bioregion, B. W. Molony, S. J. Newman, L. Loll, R C J Lenanton, B. Wise Apr 2011

Are Western Australian Waters The Least Productive Waters For Finfish Across Two Oceans? A Review With A Focus On Finfish Resources In The Kimberley Region And North Coast Bioregion, B. W. Molony, S. J. Newman, L. Loll, R C J Lenanton, B. Wise

Fisheries Research Articles

The marine ecosystems of Western Australia, including those in the Kimberley, are classified as being of moderate to low productivity. This is primarily a consequence of the influence of the Leeuwin Current, the eastern boundary current that flows poleward delivering warm, low nutrient waters, and only sporadic short-term upwelling events to shelf habitats off the Western Australian coast. This, coupled with little riverine inflow from old weathered terrestrial systems, results in low levels of primary and secondary production in habitats along most of the coast. The consequence is that finfish fisheries in the Kimberley and throughout the State typically land …


Native Vegetation In Western Australia Is Actively Involved With Soil Formation, Doug Sawkins, William H. Verboom, John S. Pate Mar 2011

Native Vegetation In Western Australia Is Actively Involved With Soil Formation, Doug Sawkins, William H. Verboom, John S. Pate

Bulletins 4000 -

Many adverse situations in Western Australian agriculture have arisen because in the past we cleared native perennial vegetation below safe ecological limits in order to grow annual crops and pasture. In retrospect, we did not fully understand the functioning of the native ecosystems concerned and thus did not foresee the long-term consequences. Research into the survival techniques of native species provides important lessons for future farming. By understanding the behaviour of plants and soils we can maximise their use in a sustainable way. Knowledge of the water acquisition and storage strategies of native plants in seasonally dry areas may be …
