Mealybug management

  • Date: 2012-09-01
  • Author: Braybrook, David

Mealybugs are sap-sucking insects that live on a wide range of host plants. They can infest vines and affect grapes, producing honeydew, which encourages the growth of sooty moulds. Mealybugs have also been associated with the transmition of grapevine viruses.

Light brown apple moth

  • Date: 2012-07-01
  • Author: Braybrook, David

The light brown apple moth (LBAM, Epiphyas postvittana) is a native ‘leaf-roller’ that has a wide host range, including numerous broadleaf weeds, horticultural crops and native species. While this moth is found across Australia, its impact on grape production varies significantly between regions, vineyards and seasons, making it important to take a strategic approach to management.

Cover crops and plant-parasitic nematodes

  • Date: 2012-06-01
  • Author: Penfold, Chris and Collins, Cassandra

Nematodes are wormlike invertebrate animals that are unsegmented. They are cold-blooded, so their metabolic rate and activity are lower in cold conditions. Of the known nematode species, approximately 14 per cent are plant parasites and 25 per cent are free-living, feeding on fungi, bacteria or detritus (Westerdahl et al. 1998). In vineyards, many of the soilborne nematodes are desirable species, which add to the faunal biodiversity, but the plant-parasitic species can cause considerable damage to grapevines.

Phomopsis cane and leaf spot management

  • Date: 2012-06-01
  • Author: Rawnsley, Belinda

Phomopsis cane and leaf spot (Phomopsis) of grapevine is caused by the fungus Phomopsis viticola. Phomopsis infects grapevines grown in many viticulture regions of Australia but has not been reported in Western Australia.

This fact sheet provides information about managing botrytis bunch rot between pre-veraison and harvest.

Australian grapevine yellows

  • Date: 2011-07-01
  • Author: Constable, Fiona and Rodoni, Brendan

Australian grapevine yellows disease (AG Yd) is observed in many Australian grape growing regions from spring through to late summer and is associated with three phytoplasmas (simple bacteria): Candidatus Phytoplasma australiense (Australian grapevine yellows phytoplasma or CPa), Tomato Big bud phytoplasma (TBBp) and Buckland Valley grapevine yellows phytoplasma (BVGYp). The disease is named to distinguish it from grapevine yellows diseases that occur overseas and are associated with other phytoplasma species that have different biology and epidemiology to CPa, TBBp and BVGYp. A higher incidence of AG Yd occurs in the warmer inland districts of the Murray Valley in NSW and Vic, the Riverland in NSW and the Riverland in SA compared with other Australian grape growing regions.

Grapevine fleck and associated viruses

  • Date: 2011-07-01
  • Author: Constable, Fiona and Rodoni, Brendan

Fleck disease is named for the appearance of affected leaves on Vitis rupestris and is associated with grapevine fleck virus (GFkV). Many grapevine varieties and rootstocks infected by GFkV alone are symptomless although infection may be associated with graft incompatibilities.
