Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones
Tomato Spotted Wilt Virus And Its Management, Lindrea Latham, Roger Jones
Journal of the Department of Agriculture, Western Australia, Series 4
In 1993, western flower thrips, an important pest of horticultural crops, was found in Western Australia. Since then there has been an upsurge in damsging virus disease epidemics caused by tomato spotter wilt virus in horticultural crops. This has occurred because western flower thrips is a more effective vector of tomato spotted wilt virus than other thrips species. Lindrea Latham and Roger Jones outline the symptoms, spread and management of this serious virus disease in vegetables and ornamentals.

Western flower thrips (Franklinislla occidentalis Pergands) is a serious pest of floral and vegetable crops. From its original habitat in western USA it has now spread throughout North America, Mexico, New Zealand and Europe. David Cook, Ian Dadour, Ernis Steiner and Brett Scourse outline its biology and the control options available.
Choosing Shower Dips For Sheep Lice, Tony Higgs, Bob Love
Choosing Shower Dips For Sheep Lice, Tony Higgs, Bob Love
Journal of the Department of Agriculture, Western Australia, Series 4
The performance of all shower dip chemicals for sheep lice can vary depending on the active chemical and the conditions under which they are used.
Department of Agriculture trials have indicated that the wettable powders coumaphos and magnesium fluorosilicate were less effective at eradicating sheep lice than were synthetic pyrethroid and organophosphate dipping chemicals.
However, failure to eradicate sheep lice may be the result of several factors, many of them related to management.
Broadacre Pest Control After Ddt, P J. Michael
Broadacre Pest Control After Ddt, P J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
DDT may no longer be applied to broadacre crops grown in Western Australia. It is being replaced by other more effective chemicals and with new methods of pest control. DDT was the most effective chemical for the control of several major broadacre pests in this State and farmers may well wonder why this change was necessary and how they will manage without DDT.

Learning To Live With Spotted Alfalfa Aphid, M Grimm
Journal of the Department of Agriculture, Western Australia, Series 4
The spotted alfalfa aphid which can devastate lucerne crops and perhaps also medic pastures, has been established in Western Australia since early 1978. However several methods of control are being developed, which could allow continued production of lucerne.

New Policy Hits Hard At Sheep Lice, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
In March 1977 the regulation requiring compulsory routine dipping of all sheep within 30 days of shearing changed, and only infested flocks were required to be dipped. This change has allowed concentrated eradication efforts.
A New Approach To Grain Insect Control, G D. Rimes, M. T. Sexton
A New Approach To Grain Insect Control, G D. Rimes, M. T. Sexton
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian farmers now have a legal responsibility to control stored grain insects on their farms.
Ten species of insects, usually referred to collectively as 'weevils', have been 'declared' under the Agriculture and Related Resources Act.
In Western Australia, grain storage insects are not found in standing cereal crops. Thus, it should be possible to set up a clean delivery "pipeline" from the paddock to the C.B.H. bin.
Armyworm Control In Coarse Grain Crops, G D. Rimes
Armyworm Control In Coarse Grain Crops, G D. Rimes
Journal of the Department of Agriculture, Western Australia, Series 4
Investigations of armyworm infestations carried out in Western Australia during 976 have shown that a complex of three species is involved in the spasmodic outbreaks that may cause damage to course grain crops.
This article looks at the economics of control methods.
Cattle Fertility Not Harmed By Pour-On Insecticides, D J. Barker
Cattle Fertility Not Harmed By Pour-On Insecticides, D J. Barker
Journal of the Department of Agriculture, Western Australia, Series 4
Pour-on insecticides have been a feature of lice and fly control on cattle for many years and in many countries, but it seems that only in Western Australia have they been suspected of lowering fertility.
Frequent reports of this effect have been received by the Department of Agriculture since the first pour-on insecticide was marketed in W.A. in the late 1960's, culminating in the research work reported below.
The work clears pour-ons as a cause of reduced fertility in herds.
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 …
Chemicals For Argentine Ant Control, Clee Francis Howard Jenkins, P. N. Forte
Chemicals For Argentine Ant Control, Clee Francis Howard Jenkins, P. N. Forte
Journal of the Department of Agriculture, Western Australia, Series 4
The Argentine ant is one of the most serious ant pests in the world and as such, has been the subject of large-scale control campaigns in several countries.
Early control measures against the Argentine ant in Western Australia involved quarantine of infected areas and the use of arsenical baits, based mainly on the so-called U.S. Government formula.
Since this time the hunt has been on for a more effective chemical, without undesirable effects.
Effect On Bees Of Insecticides Used On Rape, A C. Kessell
Effect On Bees Of Insecticides Used On Rape, A C. Kessell
Journal of the Department of Agriculture, Western Australia, Series 4
Rapeseed could provide beekeepers in Western Australia with a valuable new honey crop—hut insecticidal spraying of rape at flowering time is a potentially serious threat to most commercial beekeepers.
There are indications that insect pollination may improve rapeseed yields, so both growers and beekeepers could gain from a co-operative approach to the problem. Spraying after sundown and preventing spray drift to nearby apiaries should avoid most losses.
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

Fruit Fly, D G. Shedley
Fruit Fly, D G. Shedley
Journal of the Department of Agriculture, Western Australia, Series 4
FRUIT fly control is compulsory! To obtain effective control of fruit fly it is necessary to combine strict orchard hygiene with bait spraying.
In addition, cover spraying with DIPTEREX will give extra protection to stone fruit and pears.
When the breeding powers of the fruit fly are considered it is easy to understand why home growers and orchardists need to fight a continual battle against this pest.
Fruit Fly Control With Rogor 40 And Lebaycid : Progress Report, D G. Shedley
Fruit Fly Control With Rogor 40 And Lebaycid : Progress Report, D G. Shedley
Journal of the Department of Agriculture, Western Australia, Series 4
THE Mediterranean fruit fly has been present in Western Australia for over 60 years and during that time many types of insecticides have been tested against the pest.
Traps and lures were amongst the earliest control measures adopted, but these gave way to sugar solutions poisoned with such materials as arsenic and sodium fluosilicate.
Cattle Lice : Spray Now For Prevention, F C. Wilkinson
Cattle Lice : Spray Now For Prevention, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH lice infestation can occur in any season of the year, the heaviest infestations are found during the winter.
This build up of lice infestation normally starts in the autumn but if the cattle are treated by spraying at this period, the majority of the lice are killed and the build up is prevented.
Thus the old saying "Prevention is better than cure" certainly applies with regard to cattle lice.
Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace
Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace
Journal of the Department of Agriculture, Western Australia, Series 4
THE red-legged earth mite, Halotydeus destructor (Tuck.), and the lucerne flea, Sminthurus viridis (L.), are at present controlled effectively, cheaply and safely by a combined DDT/malathion spray (Jenkins, 1956, 1957) and this continues to be the general recommendation for farmers.
However, this combination has some disadvantages. The DDT in the spray ensures some residual control of the earth mite but has the unfortunate property of toxicity to the bdellid mites which are useful predators of the lucerne flea.
The malathion in the spray assists the DDT to control the earth mite and provides a good, quick kill of the lucerne …
