Applying virtual fencing technology for grazing and crop management: three case studies with cattle in southern Australian mixed farming systems

Jackie Ouzman, Dana L. M. Campbell, D. J. MOWAT, Jim M. Lea et autres

Context Advancements in agricultural technologies for animal management such as virtual fencing have applications in crop–livestock mixed farming systems. Targeted control of grazing cattle could, for example, improve weed management or optimise groundcover to mitigate erosion risk. Aims This research applied the …

Within-field extrapolation away from a soil moisture probe using freely available satellite imagery and weather data

R. G. V. Bramley, Eileen M. Perry, Jonathan Richetti, André Freitas Colaço et autres

Abstract Recognition of the importance of soil moisture information to the optimisation of water-limited dryland cereal production has led to Australian growers being encouraged to make use of soil moisture sensors. However, irrespective of the merits of different sensing technologies, only a …

Automated Virtual Fencing Can Effectively Contain Sheep: Field Trials and Prospects

Dana L. M. Campbell, Sue Belson, Jim M. Lea, Jackie Ouzman et autres

Virtual fencing technology uses on-animal devices to communicate boundaries via a warning audio tone and electrical pulse signals. There is currently limited validation work on sheep. This study used modified cattle eShepherd® virtual fencing neckbands on reduced-wool sheep with clipped necks to …

Monitoring of Plutella xylostella adults by pheromone traps — A report of a collaborative trial

Jan Theunissen, J. Freuler, Martin Hommes, D. J. MOWAT et autres

Plutella xylostella is a member of the lepidopterous pest complex in cabbage crops in western Europe. The species can reach damaging population levels in warm and dry summers but in adverse weather conditions its populations remain small. Because this potential pest does …

The control of cabbage root fly, Delia hrassicae (Wied.), in transplanted brassicas by insecticide application to the seedbed — A report of collaborative work

D. J. MOWAT

A research programme was initiated to confirm the effectiveness of, and extend familiarity with, a method of cabbage root fly control which involves minimal use of insecticide. Several workers throughout Europe co-operated. The method requires the application of chlorfenvinphos or chlorpyrifos to …

Emergence of cabbage root flies from puparia collected throughout northern Europe

S. Finch, B. Bromand, Étienne Brunel, ROSEMARY H. COLLIER et autres

The patterns of cabbage root fly emergence throughout the mainland of northern Europe were equally as variable as those recorded in the United Kingdom. Only the populations from Denmark were as early-emerging as the Wellesbourne flies. In the remaining populations between 15% …

Virtual Fencing Technology Excludes Beef Cattle from an Environmentally Sensitive Area

Dana L. M. Campbell, Jackie Ouzman, D. J. MOWAT, Jim M. Lea et autres

The eShepherd® virtual fencing system being commercialized for cattle has the potential to exclude cattle from environmentally sensitive areas. Animals are given audio cues to indicate a fence line via a neckband device. An electrical pulse is administered if the animal continues …

Measuring and Modeling the Water Balance in Low-Rainfall Cropping Systems

Anthony Michael Whitbread, Munir Paul Hoffmann, Christopher W. Davoren, D. J. MOWAT et autres

Abstract. In low-rainfall cropping systems, understanding the water balance, and in particular the storage of soil water in the rooting zone for use by crops, is considered critical for devising risk management strategies for grain-based farming. Crop-soil modeling remains a cost-effective option …

Oviposition and hatching of the clover weevil Sitona lepidus Gyll. (Coleoptera: Curculionidae)

D. J. MOWAT, Sam Clawson

Abstract The phenology and some aspects of the biology of the clover weevil Sitona lepidus Gyll. were studied in the field and the laboratory. Oviposition and hatching were temperature dependent. Most eggs were laid in September and October, although there was also …
