Fungicidal Control Of Wheat Leaf Diseases, A G P Brown

Experimental Summaries - Plant Research

In a further experiment on fungicides to protect wheat during flowering and grain fill from Septoria nodorurn at Badgingarra Research Station, rates below 1 litre and lower carrier volumes were compared for the fungicide Tilt applied at Zadoks stage 50. A few other fungicides were also included. At spraying there was a moderate infection by Septoria nodorurn (85% of leaf damage), Septoria tritici (10%) and Pyrenophora tritici-repentis (5%). Good control was obtained with most treatments (Table 1) with only Benlate at 1 kg/ha appearing ineffective when percentage disease was rated on October 10, 1985. At October 17 disease scores differed …

Foliar Disease Of Wheat, A. G. P. Brown

Experimental Summaries - Plant Research

Wheat leaf diseases were at much reduced levels in 1984. This may have been caused by prolonged summer rain prematurely setting off dispersal of spores and also initiating microbiological breakdown of stubble residues. No survey was carried out in 1984 but a good indication of the seasonal effect can be gained by noting that in the spray-timing experiment at Badgingarra disease levels were extremely low until the end of August some 90 days after sowing. Timing of fungicide for Septoria and Yellow Spot control. 84BA32, 84GE59. Effect of Yellow-spot at Merredin (with S. Trevenen) 84ME57. Yellow-spot is common though not …

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 …
