Foliar Diseases Of Wheat, A. G. P. Brown
Foliar Diseases Of Wheat, A. G. P. Brown
Experimental Summaries - Plant Research
Leaf disease in the wheatbelt. Wheat leaf diseases were common north of Perth. They were severe in the Moora district and catastrophic in the northern wheatbelt. Yellow spot (Pyrenophora tritici-repentis) and glume blotch (Septoria nodorum) were the major pathogens in most areas with yellow spot exceeding glume blotch in area of leaf affected for the first time since surveys began in 1971. In the south dry conditions prevailed and diseases were hard to find. Figure 1 gives the distribution in the various zones for 1983 excluding the Esperance district which was not surveyed. Stress damage induced mostly by water stress …

Annual Medics For The Kalgoorlie Region And Adjacent Eastern Rangeland Zones, G Gintzburger
Experimental Summaries - Plant Research
Species selection and establishment methods Extensive overgrazing and burning of the dominant winter rainfall Goldfields pastoral zones have left large areas degraded with a poor annual vegetation cover of nearly no grazing value. Thus, more grazing pressure is exerted on shrubs and small trees accelerating the desertification process. Shrubs and trees are the main stabilising agent left in a rangeland plant community when alI annuals have been grazed out. In order to upgrade or regenerate some of these areas, conventional methods of grazing prohibition or deferred grazing can be used but often, improvement obtained are slow. It is hypothesized that …

Experimental Summaries - Plant Research
Residue Trials: Breakdown rates have been established for trifluralin at Wongan Hills and Avondale over the past two seasons. The decay curve follows a hyperbolic curve rather than the expected exponential curve with constant half life, probably due to the considerable loss of chemical by volatalization in the first few days, before biological decomposition takes over as the main breakdown factor.
