title: SH1248021.09FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

title: Technical and economic viability of a forecasting system for the management of onion downy mildew

description: ABSTRACT Onion downy mildew caused by tlid-translationPeronospora destructortlid-translation requires weekly spraying of fungicides for its control and, in order to reduce this number, the present study aimed to technically and economically evaluate a disease forecasting system and compare it with the conventional control system. A randomized block design with four replicates and four treatments was established in 2018 and 2019 in Rio do Sul City (Santa Catarina State, Brazil) with the onion cultivar Empasc 352 - Bola Precoce. For the conventional system, spraying started one week after transplanting and was weekly performed during the crop cycle with a treatment using protective fungicide and another treatment using systemic fungicide. For the forecasting system, spraying was performed after 30 days, adopting the system validated by Marcuzzo, when the disease severity value (DSV) reached twelve points and the same types of fungicides used in the conventional system for each treatment. The forecasting system had the protective fungicide reapplied when accumulated rainfall was 25mm. Area under the disease progress curve, final severity, disease progression rate and yield did not differ between treatments, but the reduction in the number of sprays for the protective fungicide in the forecasting system was 31% and 43% smaller than that in the weekly application system in 2018 and 2019, respectively, while such a reduction was 62% for the systemic fungicide in both years. The forecasting system allowed a reduction in the cost with systemic fungicide of R$ 3,000.00 and R$ 3,500.00/ha for the respective years, compared to the conventional system, while with the protective fungicide the cost reduction was R$ 210.00 and 480.00/ha for 2018 and 2019, respectively. The forecasting system has proven to be a viable tool for the management of onion downy mildew in Santa Catarina State, Brazil, and is available for the production chain at http://www.ciram.sc.gov.br/agroconnect/.

title: Temporal progress of maize diseases

description: ABSTRACT The aim of the present study was to evaluate the temporal progress of the diseases southern rust (Puccinia hpspolysorahps), Cercospora leaf spot (Cercospora hpszeaehpsatn-atnmaydis), white spot (Pantoea hpsananatishps) and spot blotch (Exserohilum hpsturcicumhps) in corn, as well as their correlation with climate variables. Experimental design was in complete blocks with random treatments. The monomolecular model best fit to the epidemics. Using the severity data from each disease, correlations were established with the climate variables (DFtemp-favorable days with temperatures between 18-28 ºC; DFumid-favorable days with relative humidity&gt;60%; PrecAcc-cumulative rainfall; PrecDia-precipitation/day, and Prec10- precipitation&gt;10 mm) observed during the evaluation period. After analyses, it was possible to infer that the variable cumulative precipitation was determinant for the occurrence of epidemics of the studied diseases.

title: Epidemiological aspects of Botrytis leaf blight in the region of “Alto Vale do Itajaí”, Santa Catarina State, Brazil

description: ABSTRACT With the aim of studying the epidemiology of Botrytis leaf blight, caused by Botrytis squamosa in the region of Alto Vale do Itajaí, Santa Catarina State, Brazil, an assay was conducted with naturally infected plants in 2017 and 2018 growing seasons. Every seven days, for 10 weeks, the population of conidia in the air was quantified, the environmental conditions were recorded and the severity in plants was evaluated. Even in an environment favorable to the disease, its onset occurred five weeks after sowing. The epidemic started one week after the first detection of inoculum in the air in 2018. The disease progress was represented by the Gompertz model y=0.51830*(exp(-5.95660*exp(-0.47392*x))). Fresh biomass production of seedlings was 1.68 and 2.8 grams per plant in the respective evaluation years. This epidemiological study can provide information about the beginning of the epidemic and will be useful in the validation of a forecasting system for Botrytis leaf blight in onion.

title: Elaboration and validation of a digrammatic scale to evaluate soybean bacterial pustule

description: ABSTRACT Bacterial pustule, caused by the bacterium Xanthomonas axonopodis pv. glycines, is considered one of the most important bacterial diseases affecting soybean. The aim of this study was to develop and validate a diagrammatic scale for assessing the severity of soybean bacterial pustule. To elaborate the scale, soybean leaflets with different severity levels were collected to determine the maximum and minimum values of disease severity, while intermediate levels were established according to Weber-Fechner law of visual stimulus. The values proposed for the scale were 1.4%, 3%, 6%, 9%, 20% and 29.5%. To validate the scale, eight evaluators, with no experience in bacterial pustule evaluation, assessed 39 photos of leaflets with different severity levels, without and with the aid of the scale. The results of severity estimated by the evaluators were related to the actual severity values (determined with Assess 2.0 software from digital images of leaves with symptoms) and analyzed with simple linear regressions to assess the accuracy of evaluators. The precision of evaluators was determined based on the coefficients of determination and the variance in absolute errors. Estimates using the proposed diagrammatic scale indicated a significant increase in the coefficient of determination and lower variance in absolute errors, providing greater precision and accuracy of evaluations, which could be adopted to assess the severity of soybean bacterial pustule.

title: Fungal diseases in grapevines cultivated in open field and under waterproof cover

description: ABSTRACT The use of protected cultivation in grapevines has increased with the aim of reducing the occurrence of fungal diseases. Therefore, an experiment was carried out with the cultivars ‘Isabel’, ‘Isabel Precoce’, ‘Bordô’ and ‘Concord’ produced in sequential summer and winter crop seasons and managed in open field and under waterproof plastic cover, without fungicide application. The aim of this study was to verify the severity of the major fungal diseases (downy mildew, anthracnose, leaf spot and grape vine rust) and defoliation under those conditions. The use of plastic cover, during both the summer and the winter crop seasons, reduces the severity of the main fungal diseases and defoliation for the evaluated grapevine cultivars. ‘Bordô’ showed higher tolerance to fungal diseases when compared to the other cultivars. Yield values for vines managed under protected cultivation were higher than those found for vines grown in open field.

title: Root and Stem Rot by Phytophthora sojae Kaufm. & Gerd. in the eastern high plains of Meta Department.

description: ABSTRACT The oomycete Phytophthora sojae has been reported to cause “Damping off” during pre and post-emergence, as well as root and stem rot in soybean crops worldwide. The increase in the soybean planted area in Colombia, in the region of eastern high plains of Meta Department, and the presence of highly favorable environmental conditions led to the appearance of seedling damage symptoms, which could be caused by a pathogen complex that includes P. sojae. This study aimed to identify the causal agent of root and stem rot in soybean crops in the region of Meta Department through microbiological and molecular diagnosis of 84 affected tissue samples. Morphological characterization of the causal agent and macroscopic characterization of colonies were performed in modified V8 medium. Molecular identification was done by amplification of the ITS region. Phylogenetic comparison employed ITS sequences reported in previous studies and deposited in the GenBank for different species of the genus Phytophthora, isolates of the species P. sojae from different geographical regions and the sequences of P. sojae obtained in this study. Of the 84 samples analyzed during 2015-2017, seven (7) samples corresponding to 8% showed typical symptoms of root and stem rot, which were attributed to P. sojae, confirming Koch’s postulates. The remaining 77 samples corresponding to 92% presented symptoms of the “Damping off” complex and were associated with Pythium spp. and Fusarium spp. This is the first report of the presence of P. sojae and its participation as a causal agent of root and stem rot in commercial areas of soybeans in the eastern high plains of Meta Department.
