13. Asian Rust control and performance of two soybean cultivars submitted to different fungicides and application time / Controle de ferrugem asiática e desempenho de duas cultivares de soja submetidas a diferentes fungicidas e épocas de aplicações
Phakopsora pachyrhizi Syd. &Syd. is the worst threat for soybean crop in the main producers regions around the world, where significant loses has been observed. Many variables in the quantification of damage of this disease have to be studied, such as area under the disease progress curve (AUDPC), healthy leaf area absorption (HAA), healthy leaf area duratio

14. NOVAS ABORDAGENS ANALÍTICAS PARA A DETERMINAÇÃO DE CICLOFENIL POR FLUORIMETRIA APÓS DERIVAÇÃO FOTOQUÍMICA E PARA AS DETERMINAÇÕES VOLTAMÉTRICAS DE ESTROBILURINAS UTILIZANDO O ELETRODO DE MERCÚRIO E DE CD (II), CU (II) E PB (II) UTILIZANDO O ELETRODO DE FILME DE BISMUTO / NEW ANALYTICAL APPROACHES FOR SPECTROFLUORIMETRIC DETERMINATION OF CYCLOFENIL AFTER PHOTOCHEMISTRY DERIVATION AND FOR STROBILURIN VOLTAMMETRIC DETERMINATION USING MERCURY ELECTRODE AND CU (II) VOLTAMMETRIC DETERMINATION USING BISMUTH FILM ELECTRODE
In this work, analytical approaches for the selective determinations of cyclofenil, stroblilurins (azoxystrobin and dimoxystrobin) and Cu (II) have been developed. The determination of cyclofenil was made by taking advantage of their fluorescent photoderivative. In order to achieve maximum fluorescence (250/410), the best conditions for derivatization and fo

15. Partial resistance and fungicides on soybean asian rust control / Resistência parcial e fungicidas no controle da ferrugem asiática da soja
Soybean asian rust, caused by the fungus Phakopsora pachyrhizi, is one of the major pest problems in the crop. Disease control has required a combination of cultural practices to minimize losses. Among the control methods, chemical control with fungicides, has been the only one available. Control strategies, such as the use of cultivars with partial resistan

17. A Strobilurin Fungicide Enhances the Resistance of Tobacco against Tobacco Mosaic Virus and Pseudomonas syringae pv tabaci1
The strobilurin class of fungicides comprises a variety of synthetic plant-protecting compounds with broad-spectrum antifungal activity. In the present study, we demonstrate that a strobilurin fungicide, F 500 (Pyraclostrobin), enhances the resistance of tobacco (Nicotiana tabacum cv Xanthi nc) against infection by either tobacco mosaic virus (TMV) or the wi

18. Role of the PDR Gene Network in Yeast Susceptibility to the Antifungal Antibiotic Mucidin
Yeast strains disrupted in the PDR1, PDR3, or PDR5 gene, but not in SNQ2, exhibited higher sensitivity to mucidin (strobilurin A) than did the isogenic wild-type strains. Different gain-of-function mutations in the PDR1 and PDR3 genes rendered yeast mutants resistant to this antibiotic. Mucidin induced PDR5 expression, but the changes in the expression of SN
