The population structure of Hemileia vastatrix in Brazil inferred from AFLP
Maia, T. A.; Caixeta, E. T.; Mizubuti, E. S. G.; Zambolim, L.; Maciel-Zambolim, E.Efforts to obtain durable resistant cultivars to coffee leaf rust have a long history of disappointment because of the lack of information on the Hemileia vastatrix evolutionary potential. In this study, the AFLP marker was used to analyze the genetic structure of a field population of H. vastatrix from different coffee genotypes cultivated in a wide geographic region of Brazil’s main production areas. A total ...
Coffee bacterial diseases: a plethora of scientific opportunities
Badel, J. L.; Zambolim, L.Coffee is a very important crop for several tropical countries across different continents. The diseases bacterial halo blight (BHB), bacterial leaf spot (BLS), bacterial leaf blight (BLB) and coffee leaf scorch (CLS), caused by the bacterial pathogens Pseudomonas syringae pv. garcae (Psgc), P. syringae pv. tabaci (Psta), Pseudomonas cichorii (Pch) and Xylella fastidiosa subsp. pauca (Xfp), respectively, cause ...
The field resistance of potato cultivars to foliar late blight and its relation...
Duarte, H. S. S.; Zambolim, L.; Mizubuti, E. S. G.; Pádua, J. G.; Ribeiro Júnior, J. I.; Nogueira Júnior, A. F.; Carmo, E. L.The use of resistant cultivars is the preferred control method for plant diseases. This approach is attractive owing to its high efficacy, low cost, and ease of implementation. This work aimed to assess the resistance of potato cultivars to foliar late blight (Phytophthora infestans) under different environmental conditions. It further aimed to assess the relationships between resistance to foliar late blight a...
Climate favourability to leaf rust in Conilon coffee
Capucho, A. S.; Zambolim, L.; Cabral, P. G. C.; E. T. Caixeta; Maciel-Zambolim, E.The Brazil is the second largest producer of Conilon coffee (Coffea canephora), being the state of Espírito Santo responsible for producing 9.7 million bags of Conilon coffee. The biology of Hemileia vastatrix, etiologic agent of leaf rust, the main disease of this culture, is not well understood under the environmental conditions of Espírito Santo, Brazil. This study determined the ideal temperature and leaf w...
Insecticide use and organophosphate resistance in the coffee leaf miner Leucopt...
Fragoso, D. B.; Guedes, R. N. C.; Picanço, M. C.; Zambolim, L.Increasing rates of insecticide use against the coffee leaf miner Leucoptera coffeella (Guérin-Méneville) and field reports on insecticide resistance led to an investigation of the possible occurrence of resistance of this species to some of the oldest insecticides used against it in Brazil: chlorpyrifos, disulfoton, ethion and methyl parathion. Insect populations were collected from ten sites in the state of M...
Photosynthetic and antioxidative alterations in coffee leaves caused by epoxico...
Honorato Júnior, J.; Zambolim, L.; Aucique-Pérez, C.E.; Resende, R.S.; Rodrigues, F.A.Coffee leaf rust (CLR), caused by Hemileia vastatrix, is a major disease affecting coffee production worldwide. In this study, an in-depth analysis of the photosynthetic performance of coffee leaves challenged or not with H. vastatrix and sprayed with either epoxiconazole (EPO) or pyraclostrobin (PYR) was performed by combining chlorophyll a fluorescence images, photosynthetic pigment pools and the activities o...
Influence of leaf position that correspond to whole plant severity and diagramm...
Capucho, A. S.; Zambolim, L.; Duarte, H. S. S.; Parreira, D. F.; Ferreira, P. A.; Lanza, F. E.; Costa, R. V.; Casela, C. R.; Cota, L. V.The main objective of this research is to determine the influence of leaf position on corn plants with white spot caused by Pantoea ananatis, which better represents the infection on the whole plant. A diagrammatic scale to quantify the severity of the disease was elaborated and validated. For scale elaboration, the minimal and maximal limits of the disease severity observed in the field were considered, and in...
The Híbrido de Timor germplasm: identification of molecular diversity and resis...
Silva, R. A.; Zambolim, L.; Castro, I. S. L.; Rodrigues, H. S.; Cruz, C. D.; Caixeta, E. T.The main phytosanitary problems affecting global coffee production are the fungal diseases known as rust, caused by Hemileia vastatrix Berkeley and Broome, and coffee berry disease (CBD), induced by Colletotrichum kahawae Waller and Bridge. The main disease control strategy is the use of resistant coffee cultivars. Híbrido de Timor is the most important source of resistant varieties used in breeding programs wo...
Persistência do fungicida triadimenol em solos
Albuquerque, M. A.; Schaefer, C. E. R.; Loures, E. G.; Zambolim, L.O grau de persistência do fungicida triadimenol, que é utilizado intensamente no controle da ferrugem do cafeeiro, foi avaliado em amostras de duas classes de solo, Podzólico Vermelho-Amarelo câmbico (PV) e Latossolo Vermelho-Amarelo variação Una (LU) da região de Viçosa, MG, com e sem adição de composto orgânico. Utilizou-se a técnica de bioautografia em camada fina. O triadimenol foi adicionado a 375 mg kg-1 ...
