Cucurbit production systems in Australia and biosecurity risks associated with viral pathogens

Abstract Viral infection is a key limiting factor to cucurbit production globally. The viral population within Australia differs from that elsewhere in the world it represented by relatively few pathogens small number of virus families. infections induce range physical deformities and discoloration on leaves fruit commodities. Typically, result decline marketable yield even plant death extreme cases. Identifying exotic issues analysis existing preparedness plans, surveillance programs diagnostic options are critical biosecurity strategies required mitigate introduction new into Australia. This review discusses threat viruses pose Australian systems inherent difficulties associated with managing pathogens.
