Emergence and epidemics of a new disease in araguaia valley: anthracnosis of co...
Juliatti, Fernando Cezar; Juliatti, Fernanda Cristina; Juliatti, Breno Cezar Marinho; Paula, Cristiane Aparecida deCotton culture (Gossypium hirsutum L.) is trending in an upward expansion amidst Brazilian “cerrado”. Due this growth, new pathosystems are growing in incidence on tropical fields in the region of Araguaia Valley - MT. Surveys and material collection were conducted out in production areas on two counties (Bom Jesus - MT and Canarana – MT), both regions represents a total amount of 50.000 hectares of cultivated ...
Association of "green spot" and defoliation to Tenuipalpus heveae incidence and...
Cezar Juliatti, Fernando; Inácio da Fonseca, Héloi; Carneiro, Maria Angélica Barcelos; Juliatti, Breno Cezar Marinho; Santos Nascimento, Lucas dosAccording to IBGE data, in 2016, Brazil produced closer to 56 thousand hectares of rubber tree generating a total latex production of 315.62 tons in commercial areas and 1.6 thousand tons in native forests. But this growth in crop production is related to the raise of economic losses generated by foliar and bark (panel) diseases caused by Phytophthora spp, Colletotrichum sp., Lasiodiplodia spp., Colletotrichum ...
Evaluation of the gelatin technique for the preservation of phytopathogenic fungi
Beloti, Igor Forigo; Juliatti, Breno Cezar Marinho; Juliatti, Fernando CezarThe preservation methods for fungi have great importance in ex situ collections, representing important biological heritage, useful for mycologists and plant pathologists in several scientific works. However, there is a lack of studies for a suiTable and efficient preservation method for the different groups of fungi. Although, the most appropriate is the one that maintain, even after long periods, the original...
Sensitivity of two isolates of Phakopsora pachyrhizi to dithiocarmamate, chloro...
Juliatti, Fernando Cezar; Polloni, Lorraine Cristina; Prado, Tâmara Morais; Zacarias, Nadia Romina Shneider; Silva, Erick AraújoAsian soybean rust (ASR), caused by the phytopathogen Phakopsora pachyrhizi Sydow & Sydow, is a worldwide distributed fungal disease responsible for causing damages in soybean crops [Glycine max (L.) Merril] of up to 90% of its productive potential. So far, due to limited availability of resistant varieties, fungicide application is the most widely used strategy for ASR control, although some populations of...
Análise de genótipos de soja quanto à resistência ao nematoide do cisto
Juliatti, Breno Cezar MarinhoThe nematodes are very abundant, as they represent 80% of individuals in the kingdom Animalia. The soybean cyst nematode (SCN), Heterodera glycines, is a great problem for soybean cultivation and it is present in about ten states of Brazil. Some species or soybean cultivars have the characteristic of resistance or alteration in survival skills and perpetuation of nematodes (female index FI), which process is ac...
Eficácia da associação de fungicidas e antibióticos no manejo da mancha branca ...
Juliatti, Fernando Cezar; Beloti, Igor Forigo; Juliatti, Breno Cezar Marinho; do Crato, Fausto FernandesA mancha branca do milho apresenta ampla distribuição pelas áreas produtoras de milho no Brasil, sendo uma das principais doenças da cultura, ao ponto de ter se tornado um entrave para a sua expansão. A doença é ocasionada por um complexo de patógenos, dificultando seu manejo pelo produtor. O presente trabalho objetiva avaliar a eficácia da combinação de diferentes fungicidas com antibióticos, no manejo da doen...
Escala diagramática para avaliação da severidade de mofo branco em soja
Juliatti, Fernando Cezar; do Crato, Fausto Fernandes; Juliatti, Fernanda Cristina; Couto, Karla; Juliatti, Breno Cezar MarinhoO patógeno Sclerotinia sclerotiorum (Lib.) De Bary ocorre em sistemas de cultivo no Brasil por décadas, mas a avaliação da severidade da doença no campo ainda não foi devidamente estabelecida com o uso de escalas diagramáticas para avaliação de fungicidas em campo, produtos biológicos e resistência de germoplasma em programas de melhoramento ou cultivares. Este trabalho teve como objetivo propor uma escala diag...
