Delaying The Development Of Herbicide Resistant Ryegrass By Using Alternative Weed Control Strategies, A. J. Diggle, G. S. Gill, J. E. Holmes

Biosecurity published reports

Alternative strategies to control ryegrass in wheat lupin rotations are worth approximately 15 dollars per hectare for each 50% reduction achieved in plant or seed numbers. This figure has been calculated for circumstances similar to those found at Wongan Hills, and it holds in all cases where ryegrass is still under control using standard herbicides.

Farmers should adopt any ryegrass strategy in addition to that normally practised, so long as the cost to control ratio is less than $15/ha/50% kill. This applies even where good control is being achieved using grass selective herbicides, regardless of the number of previous applications …

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis

Natural resources published reports

It is now some 33 years since the Ord River Regeneration Project, the largest and most ambitious of its kind in Australian rangelands, commenced.

During this time there have been a number of publications and miscellaneous reports about the project, but this publication is by far the most comprehensive produced to date. Although the field work was undertaken in 1981, the findings recorded here will stand in a good stead as a detailed account and reference work for years to come.

Much has changed within the Regeneration Reserve area since the project commenced. Cattle and feral donkey numbers have finally …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Managing Brome Grass In The Wheat:Lupin Rotation, Aik Hock Cheam, Gurget Gil, Christine Zaicou

Journal of the Department of Agriculture, Western Australia, Series 4

Some farmers and scientists are questioning the sustainability of the cereal:lupin rotation in the Western Australian wheatbelt.

Being a 'tight' rotation, its continuation is constantly under threat by disease, especially lupin root rots caused by Pleiochaeta (the brown spot organism) and Rhizoctonia fungi. To control disease, some farmers have lengthened the rotation to three years, such as wheat:wheat:lupins or wheat:barley:lupins. The longer cereal phase also helps to stabilise soil against wind erosion. However, such rotations can lead to a rapid buildup of brome grass during the two consecutive years of cereals. The implications of these rotations on the severity of …

There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.
