Durum Wheat : A Potential New Crop For Western Australia, Alfredo Impiglia, Wal Anderson
Journal of the Department of Agriculture, Western Australia, Series 4
The export orientation of our grains industries and the current favourable position of durum wheat in the world trade make this an opportune time to examine the propsects for durum wheat in Western Australia. Alfredo Impiglia and Wal Anderson summarise the known requirements for consistant production of high quality durum that will lead to the establshment of a new industry in Western Australia.
Options For Pest Management In Pastures, Phil Michael, Mike Grimm, Mike Hyder, Peter Doyle
Options For Pest Management In Pastures, Phil Michael, Mike Grimm, Mike Hyder, Peter Doyle
Journal of the Department of Agriculture, Western Australia, Series 4
Redlegged eath mit, blue oat ite, lucern flea and aphids damage pastures across southern Australia, and it has been estimated that they cause annual losses to the Australian wool industry alone of over $200 million.
Redlegged earth mite is without doubt the most serious of the four pests. Peter DoPhil Michael, Mike Grimm, Mike Hyder and Peter Doyle discuss intergrated management options to control these pests.
New Control For Esperance Armyworms, G R. Strickland, G. D. Rimes
New Control For Esperance Armyworms, G R. Strickland, G. D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
Armyworms are periodically responsible for serious cereal crop damage in Australia, often causing up to 80 per cent crop loss.
Amajor outbreak at Esperance in 1975 resulted in some 14,200 ha requiring treatment.
This was the first serious outbreak of armyworm for nine years in Western Australia.
A major new problem in the control of armyworm outbreaks is that use of DDT has been restricted by residue and withholding period problems, especially with a crop such as barley in which the grain is unprotected by glumes.
The trial results suggest that trichlorfon is a suitable material to eradicate armyworms and …

Natural Control Of Insect Pests On The Ord?, P J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
Current trials conducted by the Department of Agriculture at Kununurra are indicating that there may be an important place for biological control of insect pests of the Ord River Irrigation Area.

Rapeseed. 2. Insect Control, J A. Button, D. L. Hardy
Journal of the Department of Agriculture, Western Australia, Series 4
RAPESEED crops are highly susceptible to attack from a number of insects and, in most cases, some crop protection measures will be necessary to achieve satisfactory yields.
This article discusses the insects that have been a problem in rapeseed crops in Western Australia to date.
Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael
Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
Results of two experiments at the Ord Irrigation area in 1968 indicate that farmers may be spending more than necessary to obtain economic control of cotton pests in some seasons.
One experiment clearly demonstrated the relationship between low insect numbers and improved cotton yields—the second indicated that a moderate but well timed spray schedule, especially during the early part of the season, can result in more economic insect control than an intensive spray schedule.
Early Spraying Esential For Webworm Control, J A. Button
Early Spraying Esential For Webworm Control, J A. Button
Journal of the Department of Agriculture, Western Australia, Series 4
Results of trials conducted during the last two seasons have emphasised the need for very early treatment of webworm infested crops.
Where heavy infestations occur every effort should be made to apply treatments during the first fortnight after crop emergence
Kimberley Research Station Progress Report, 1964 : Insect Pests And Insecticides, K T. Richards
Kimberley Research Station Progress Report, 1964 : Insect Pests And Insecticides, K T. Richards
Journal of the Department of Agriculture, Western Australia, Series 4
FOR the past four years, detailed studies have been carried out in regard to the identification, status, bionomics, and control of insects and mite pests attacking the various crops grown in the Ord River Irrigation Area.

Insect Pests Of Cotton In The Ord River Irrigation Area, K T. Richards
Journal of the Department of Agriculture, Western Australia, Series 4
COTTON is grown in the Ord Valley of north Western Australia, mainly as an annual, irrigated crop during the hot summer months of the "wet season".
It is usually planted in November-December and harvested March-May.
This period of growth corresponds closely to that of maximum insect activity.
Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins
Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins

ONE of the most important factors influencing Western Australian agriculture in the last 20 years has been the development of permanent pastures together with the associated practice of ley farming.
Although the increased use of pasture plants, and particularly subterranean clover, has increased the general fertility of many areas it has also accentuated various problems, including those relating to insect control.
Summer fallow was a strong deterrent to such pests as the red-legged earth mite, the lucerne flea, and webworm and these and several other creatures have shown a tendency to increase under new farming methods.
