• Abstract

  Ratoon stunt (RSD), caused by Leifsonia xyli subsp. xyli (Lxx), is one major disease in many sugarcane-producing countries due to yield loss and difficulty of control. The use of clean seedcane is an important step towards successful control of RSD because contaminated propagating materials is the sole source of primary inoculum. Hot water treatment is the most employed method to eliminat…

• Abstract

  The gummosis caused by Phytophthora spp. is one major citrus diseases in the whole world. Planting of healthy seedling is one of most important means of disease control. The LAGEM of UFSCar is one of the licensed laboratories by the Ministry of Agriculture to carried out diagnostic service for Phytophthora detection on citrus seedling, in order to comply with the state law on citrus seddl…

• Abstract

  Ratoon stunt (RSD), caused by the fastidious bacterium Leifsonia xyli subsp. xyli (Lxx), is considered the main disease of sugarcane due to difficulty of identification in field, which hampers its control. Information on disease impact on sugarcane yield is limited in Brazil, even though it is disseminated in all states and host cultivars. The main measures of RSD control are diagnostic a…

• Abstract

  Blast is one major disease on all winter crops grown in Brazil. Wheat was the first host, succeeded by triticale, rye, barley, black oat and white oat. These diseases have called attention of the international scientific community because they had never been reported in nature as well as by the magnitude of the yield losses on all these cereals. Varietal resistance is the most recommended…

• Abstract

  The orange rust, caused by Puccinia kuehnii, is one major disease of sugarcane industry due to yield loss and economic impact, as observed in Australia. Soon after the disease reached Brazil in 2009 three varieties were identified as highly susceptible, abolished and replaced by resistant varieties. The use of resistant genotypes has been the ideal method to cope with this disease in ever…

• Abstract

  Resistant genotypes is the main strategy employed in Brazil to control orange rust of sugarcane caused by Puccinia kuehnii. This was the method employed with success to cope the first outbreak of this disease in the world, in Australia. The effectiveness of this strategy is dependent on the knowledge of pathogen diversity, which may be the cause for the different result between these two …

• Abstract

  Orange rust (Puccinia kuehnii) has been the most recent threat to sugarcane industry in Brazil. Due to yield loss it caused in susceptible varieties in other countries, they were soon identified and their multiplication interrupted all over Brazil. Nevertheless, orange rust continues to worry sugarcane pathologists since varieties with moderate resistance cover large areas and will not be…
