delivery postcode classifications, Methyl Major genes have been mapped for flesh, skin and flower colour, for tuber shape and eye depth, and for resistances to late blight, nematodes, viruses such as potato virus (PV)X, PVY, PVA, PVM and PVS and wart. animals and reproductive material, Motor vehicles, aldicarb and fozthiazate) are incorporated immediately prior to planting as part of seedbed preparation using bed-tilling machinery to provide partial control of free-living nematodes and PCN as well as wireworm larvae (Agriotes spp.). Biofumigant species for potato cyst nematode management Several seed companies supply biofumigant species. PCN control is difficult because of their biology, long survival in the absence … We acknowledge the Traditional Owners of country throughout Australia and recognise their continuing connection to land, waters and culture. Having used the system, the grower is then much more aware of the roles of resistance and tolerance to PCN, nematicides and length of rotation on managing the pest. Potato cyst nematodes can be divided into the yellow (G. rostochiensis) and the white (G. pallida) potato cyst nematode. small exporters, Exporter Both analyses are required as clustering based on molecular markers can be different to that based on pedigree (Sun et al., 2003). Several independent reviews concluded that such intense early-generation visual selection was very ineffective (Tai and Young, 1984; Caligari, 1992; Tarn et al., 1992; Bradshaw and Mackay, 1994). Also, it should be noted, infected plants take up less water (Haverkort et al., 1991) depleting soil water at a lower rate than controls. Africa (1990a) and Bowden and Rouse (1991) studied the interaction between drought and effects of Verticillium dahliae (causing ‘wilting disease’). Idaho potatoes Irrigation is widely practised both to increase yield and to improve the quality of potatoes. dwarfing of the plant and fewer crops yellow or golden potato cyst nematode (Globodera rostochiensis) is present in some areas of Victoria. Potato cyst nematode can cause complete crop failure if not controlled, and if it established in Australia, our trading partners would be likely to reject exports of any produce that could carry the pest. Industry Advisory Council (FIAC), Information In many other countries, levelling and cultivating to c. 30 cm suffice prior to planting (Stalham et al., in press). Significant damage below the ground can be done before symptoms are even visible above ground. Biosecurity measures and quarantine restrictions are in place to ensure it does not spread. Faced with the highly polyphagous Meloidogyne species, control must favour biological antagonists such as B. penetrans integrated with the use of resistant cultivated plants. 46 potato nematode) and Globodera pallida (pale potato nematode) cause major losses in potato 47 (Solanum tuberosum L.) crops [3], and are also considered as official control pests in many 48 countries [4]. Potato Cyst Nematode (PCN) is the primary pest of potato within the UK and infestation can result in tuber yield losses which exceed 80%.Overall, the pest is estimated to cost the UK potato industry about £50 million annually. Cargo This can reduce severe tuber damage during harvest by up to 50% and allow up to a 40% increase in the spot rate of harvesting (Whitney and McRae, 1992), although mechanisms for separation have improved on modern harvesters. motorcycles and machinery, Plants and plant Potato accessions rated as resistant/highly resistant (or hypersensitive/immune for virus resistance) are included in the table. A second method of parasite neuropeptide discovery relied on the identification of predicted peptides from cloned and sequenced gene transcripts. These mapping endeavours have led to several successful attempts to isolate potato genes using a map-based approach, with most of these being aimed at the isolation of major genes for resistance to the more serious pests and pathogens of potato, the late blight pathogen Phytophthora infestans (Mont.
