This poster was produced as part of HAL project VG06092 “IPM Gap Analysis for Vegetable Pathology”.

In 2007 a series of industry workshops was conducted to identify pathogens of importance, their economic impact and assess the need for new integrated pest management strategies in the Australian vegetable industry.

Priority pathogens :

Sclerotinia and viruses were consistently identified as the most important vegetable pathogens, with Sclerotinia the most highly ranked in Vic, Tas and WA, and viruses in Qld and NSW.

Of the viruses, Tomato Spotted Wilt Virus was the most predominant.

Other pathogens of importance, in order of priority, were Downy Mildew, Fusarium, Pythium, Powdery Mildew and Rhizoctonia.

Australian vegetable growers estimated total annual crop losses due to vegetable pathogens of up to $150,000 and $54,000 for greenhouse and outdoor vegetable crops respectively.
