1. Synthesis of Eugenol-Fluorinated Triazole Derivatives and Evaluation of Their Fungicidal Activity
Eugenol (C10H12O2, 4-allyl-2-methoxyphenol) is a phenolic natural product that has several biological activities and possibilities of applications. It is herein described the synthesis of eugenol-fluorinated triazole derivatives and evaluation of their fungicidal activity. The reaction of eugenol with epichlorohydrin resulted in the preparation of (±)-2-((4

2. In vitro ovicidal and larvicidal activity of Carica papaya seed hexane extract against Strongyloides venezuelensis
ABSTRACT Strongyloidiasis is a human parasitic disease caused by the helminth Strongyloides stercoralis whose treatment is particularly difficult in immunosuppressed patients due to their low responsiveness to conventional therapy. Carica papaya and its isolated compounds benzyl isothiocyanate, carpaine and carpasemine are promising compound for the treatmen

3. Quitosana associada com extratos vegetais no controle pós-colheita de antracnose em mamão ‘formosa’
RESUMO O uso excessivo de produtos químicos na cultura do mamão (Carica papaya) coloca em risco a eficácia de fungicidas, em razão dos problemas de resistência dos patógenos a esses produtos, além da possibilidade de resíduos tóxicos colocarem em risco a saúde humana e o ambiente. Diante disto, o presente trabalho teve por objetivo avaliar a eficá

4. Uso combinado de radiación UV-C y biorecubrimiento de quitosán con aceites esenciales para el control de hongos en papaya Maradol
Abstract Anthracnose and soft rot cause deterioration of quality as well as large losses during post-harvest handling of papaya fruits. The single strategies for disease control is little efficient. We analyzed the effect of to integrate control strategies on the incidence of disease caused by the inoculation of spores of the fungi Colletotrichum gloeospori

5. Phenotypic characterization of papaya genotypes to determine powdery mildew resistance
Abstract In support of breeding of papaya (Carica papaya), the disease incidence and severity of powdery mildew (Ovulariopsis caricicola) were evaluated in papaya genotypes. Two experiments in complete randomized blocks were carried out, one in the field and the other in a greenhouse. In field experiments, the lowest mean disease incidence was observed on th

6. PROCESO DE INFECCIÓN DE ANTRACNOSIS POR Colletotrichum truncatum EN PAPAYA MARADOL
ABSTRACT Colletotrichum truncatum is a pathogenic fungus causing anthracnose in papaya fruit (Carica papaya L.) and responsible for losses on postharvest. The purpose of this workwas to induce the infection process of C. truncatum on fruit of papaya cv. Maradol under controlled conditions and to describe the disease progress by histopathological and light mi

7. Genetic diversity studies of Papaya meleira virus
Papaya (Carica papaya) is a fruit crop of great economic and social importance for Brazil and other papaya-producing countries. Brazil is the second largest producer in the world. The papaya sticky disease, caused by Papaya meleira virus (PMeV), has caused great losses in the major Brazilian papaya-producing states. In order to estimate the genetic diversity

8. The wild type of Momordica charantia is not infected by potyviruses that cause disease in papaya and cucurbit crops
In the present work, the susceptibility of wild and domesticated plants of Momordica charantia to viruses from the genus Potyvirus that cause diseases in papaya (Carica papaya) and cucurbit crops was evaluated. The plants were subjected to experimental and natural infection with Papaya ringspot virus types P and W (PRSV-P and PRSV-W) and Zucchini yellow mosa

12. Desenvolvimento de métodos de detecção precoce de infecções quiescentes de Colletotrichum spp. em mamão / Development of early detections methods of quiescent infections of Colletotrichum spp. on papaya fruits
The objetives of this study were to evaluate the methods, maturation age, temperature effect, distribution and sample size to detect quiescent infection of Colletotrichum spp. (Glomerella cingulata) on papaya fruits. At first, different methods to detect quiescent infections on immature fruits were assessed: sodium hipoclorite (1,5%), paraquat (6 ml/L a.i.),
