Strawberry Root And Crown Rot Disease Survey 2005 And 2006 Seasons, Dennis Phillips, Hossein Golzar

Bulletins 4000 -

Reports of unusually high numbers of plant deaths in strawberry crops from growers in Western Australia prompted a survey to identify the cause. Plant and soil samples were taken from a range of growers and runner sources over a two-year period and tested for plant pathogens.

Fusarium oxysporum f. sp. fragariae was identified as the predominant pathogen, the first recording of this in Western Australia. Further work is planned to clarify the epidemiology of this pathogen and evaluate suitable methods of control. Patches

Root Disease Under Intensive Cereal Production Systems, Bill Macleod, Vivien Vanstone, Ravjit Khangura, Ciara Beard

Bulletins 4000 -

This Bulletin describes symptoms and control methods for the most commonly encountered cereal root diseases in Western Australia:

• rhizoctonia bare patch

• root lesion nematode

• take-all

• fusarium crown rot

• cereal cyst nematode

• common root rot

• pythium root rot

Diseases caused by pathogenic micro-organisms can significantly reduce the yield of cereals. Some of these diseases are uncommon while others occur over a large area of the Western Australian wheatbelt every year. The most prevalent root diseases of cereals in Western Australia are rhizoctonia bare patch, root lesion nematode and take-all. Less widespread are fusarium crown rot, cereal cyst nematode, common root rot …
