Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham
Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham
Journal of the Department of Agriculture, Western Australia, Series 4
There is increasing concern that brown spot and root diseases may limit the long term viability of lupin cultivation in close rotations in the agricultural areas of Western Australia. Research has found several useful strategies to reduce the impact of brown spot and Pleiochaeta root rot so that losses can be kept to a minimum. Rhizoctonia has proved more difficult to combat. Although less widespread than Pleiochaeta, it has caused severe losses and appears to be increasing in incidence, particularly in the northern wheatbelt. Research has vastly expanded our knowledge of the strains of Rhizoctonia present in our soils and …
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Journal of the Department of Agriculture, Western Australia, Series 4
In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …
Economics Of Interceptor Drains : A Case Study, Andrew Bathgate, Ian Evans
Economics Of Interceptor Drains : A Case Study, Andrew Bathgate, Ian Evans
Journal of the Department of Agriculture, Western Australia, Series 4
This case study determines the most likely rate of return to capital invested in constructing seepage interceptor drains to reduce the effect of waterlogging on crop and pasture yields. The analysis of a farm in the Denbarker region, west of Albany, determined what increases were needed in pasture growth to justify the cost of constructing drains across four adjacent paddocks. The benefits of changing rotations to include lupins were also determined, as growing lupins was unprofitable before the construction of drains.
