Ongoing surveillance of lupin crops for the disease within the zone and across NSW has found no re-occurrence of disease but  2020 seasonal conditions are similar to 2016 in many areas of NSW and there are many lupin crops that are reaching the stage now where symptoms may become obvious. Lupin anthracnose (Colletotrichum lupini) is a fungal disease of lupin plants. Most recently southern NSW crops were found with the disease in 2016, but the disease has been endemic in WA, SA and Victoria since the mid 1990’s. Some varieties of lupines are very susceptible to Lupine anthracnose, caused by the fungus Colletotrichum gloeosporioides. It is serious in Europe, South America, and, since 1996, Western Australia. foliar diseases 4 ˚˛˝˙ˆ˝ˇ˘ fi November 2017 Section 8 LUPIN 8.2 anthracnose (Colletotrichum lupini)figure 1: Anthracnose can devastate lupin plants in susceptible varieties but can be managed. lupini (Bondar) Nirenberg et al which infects all above ground parts of lupin plants and is a highly destructive disease of lupins and can cause complete crop losses in susceptible varieties. Colletotrichum . It is present in almost every country where lupins are grown and is considered the most important disease of lupins in Europe, North America and South America. Seeds can also be infected without showing visible symptoms. nose. sampled, where for every 25t of material in the consignment, 40 samples are taken, from which a 1.5kg sub-sample is obtained, tested and found free of lupin anthracnose; and; treated with a fungicide registered for the control of lupin anthracnose, at a rate specified on the label. “Last year inspections of 100 NSW lupin crops found no evidence,” Dr Lindbeck said.

In Chapter 4, anthracnose susceptibility and the disease development of lupin cultivars was assessed under natural infection of C. acutatum. White and Yellow lupins may also be tested for Bean Yellow Mosaic Virus (although this is currently rare in the UK). Lupin anthracnose is an established disease in Western Australia and South Australia, but had not been found in commercial lupin crops in NSW prior to this incident. The disease. Ongoing surveillance of lupin crops for the disease within the zone and across NSW continued for two growing seasons. The disease has potential to cause complete crop losses in susceptible varieties. Lupin anthracnose is a serious disease of lupins. How is it characterised? Lupin anthracnose has also been found in commercial lupin crops on the Eyre Peninsula and south east cropping regions of South Australia. Lupin anthracnose is established in Western Australia and has spread through wild populations of blue lupins (L. cosentinii). Lupin Anthracnose causes the stems of plants to twist and break and dead patches to appear on the leaves and pods. It is vital to ensure only seed free from anthracnose infection is used. Main stems and lateral branches can be affected, with similar symptoms also found on leaf petioles. Anthracnose is a serious disease of lupins caused by the fungus Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagendorn. However, only anthracnose produces bright pink to orange spores masses within stem lesions. NSW DPI and LLS rapidly implemented a response plan to eradicate the disease. Lupin anthracnose occurs in all lupin growing countries of the world. All notifiable plant pests and diseases must be reported within 1 working day. (SOURCE: SARDI) • Risk increases with rainfall, use of infected seed and disease The most obvious symptom in lupins is bending and twisting of stems, known as the “shepherds crook”, which is particularly noticeable when the crop is flowering (Figure 1). Accession I82 better combines anthracnose response and yield. Seed can be tested for the presence and quantity of anthracnose infection. You can report notifiable plant pests and diseases by one of the following methods: A full list of notifiable plant pests and diseases can be found in Schedule 2 of the NSW Biosecurity Act 2015. The disease can cause complete crop losses in susceptible varieties. The disease can be confused with frost injury, which can also cause collapse and premature death of the main stem. borne disease affecting stems and pods, named anthrac-. Phytophthora root rot of lupin can also result in sudden wilting and death of plants which can sometimes produce a collapsed stem. (SOURCE: SARDI) • Risk increases with rainfall, use of infected seed and disease The lesions cause the stems and lateral branches to weaken and collapse. However, only anthracnose produces bright pink to orange spores masses within stem lesions. Leaf blights that start with a half-circular brown spot at the edge of the leaf can develop into stem cankers. Anthracnose on cultivated lupins (Lupinus albus, L. angustifolius and L. luteus) was detected in Poland in 1995. Infected seeds can be malformed, and have brown lesions on the surface. For lupin, especially harmful are widely spread viruses of mosaic. Lupin anthracnose can also be spread by infected stubble through rain splash, and movement of spores by contaminated machinery, vehicles, people, animals and fodder between lupin crops and cropping areas. All lupin species are affected, but generally albus lupin (Lupinus albus) and yellow lupin (L. luteus) are more susceptible than narrow leafed lupin (L. angustifolius). Lupin anthracnose (Colletotrichum lupini) is a notifiable plant disease in NSW. A lupin anthracnose biosecurity management zone was established, restricting the planting of lupins within the zone during the eradication response. Infection of pods can lead to complete pod loss, and the production of infected seed. If infection occurs early in the season lesions can be found on seedlings. It has yet to spread in eastern Australia. Lupin anthracnose is a fungal disease of the leaves and stems. Lupin anthracnose is caused by the fungus Colletotrichum lupini, previously known as Colletotrichum... Notifiable status.

Anthracnose – Stems grow twisted and at strange angles, with lesions at the point of twisting. The fungus can survive over summer on infected stubble and spores can be splashed to re-infect seedling lupins planted into infected stubble. No reoccurrence of the disease has been found in NSW crops and it has officially been declared Absent: pest eradicated. NSW Department of Primary Industries (DPI) plant biosecurity director, Dr Satendra Kumar, said DPI had joined forces with Local Land Services and industry to kerb the disease and eradicate the fungus from NSW production areas. It is vital to ensure only seed free from anthracnose infection is used. Most recently an outbreak of the disease occurred in southern NSW in 2016, but the disease has been endemic in WA and SA since 1996. Anthracnose is a major disease of lupins in Western Australia (WA). Infected seeds can be malformed, and have brown lesions on the surface. Legislation, policy and permits. & Sacc. Anthracnose in lupins was first reported in commercial crops in Western Australia in September 1996. “This season’s surveillance is the third and final year of the operation to eradicate anthracnose from NSW following the 2016 outbreak, when the disease was found for the first time in NSW commercial lupin crops. Lupins cleared of anthracnose disease Grain Central, November 14, 2017 NEW South Wales lupin crops have been given the all clear for lupin anthracnose disease after a joint NSW Department of Primary Industries (DPI) and Local Land Services (LLS) biosecurity surveillance operation found no sign of the devastating disease. Symptoms of lupin anthracnose can be seen on all above ground parts of the host plant. It is spread from plant to plant by rain-splashed spores, and is therefore particularly damaging in wet weather. It is serious in Europe, South America, and, since 1996, Western Australia. NSW DPI and LLS rapidly implemented a response plan to eradicate the disease. Lupin anthracnose is a fungal disease of the leaves and stems. Phytopathogenic viruses, mycoplasmas and mycoplasma-like organisms have been detected or are suspected in all leguminous crops. Lupin anthracnose may lead to complete crop losses in susceptible varieties. Lupin Anthracnose update: September 2020 Update. Anthracnose is a serious disease of lupins caused by the fungus Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagendorn. Causative agents of lupin diseases are fungi, bacteria, viruses and nematodes, which cause different types of injuries: withering, decay, maculation, blotches, pustules, deformations, chloroses, etc. Affected plants are not usually killed, but can become very unsightly as a result of … The worst damage to lupin is caused by anthracnose, fusarium wilt, fusarium and other root rot, bacteria and viruses. Oval shaped lesions occur on the stem and eventually lead to collapse and bending of stems. Later in the season as the disease progresses, lesions can develop on the pods, distorting and twisting them. Lupin seed should be tested for germination and anthracnose disease (Colletotrichum gloeosporioides or C. acutatum). The current disease outbreak began in the 1980s and. Lupin anthracnose is a fungal disease causes by . It has yet to spread in eastern Australia. Restrictions have been in place since 1996 to stop whole lupin seed and plant material entering NSW from either of these states. Lupin Problems and Treatments. Lupin anthracnose has also been found in commercial lupin crops on the Eyre Peninsula and south east cropping regions of South Australia. The first is the main threat for lupin cultivation in Central and South America, whereas the latter is the cause of a disease called lupinosis in animals fed from the infected plant. Lesions produce an abundance of fungal spores which are spread through the crop by rain splash. If infection occurs early in the season lesions can be found on seedlings.
