Catão, Hugo Cesar Rodrigues Moreira; Castilho, Ítala Menegon; Caixeta, Franciele; Tebaldi, Nilvanira Donizete; Freitas, Pâmela Gomes Nakada [UNESP]Made available in DSpace on 2022-04-28T19:50:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-12; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Gherkin seeds usually show irregular physiological quality. Seed production requires fast and reliable tests to evaluate seed quality. Germination test is considered a recognized analysis method; however, seed technology has pursuit th...
Chemical control of phytophthora wilt in tomatoes
Mendonça, Laís Barbosa Prazeres; Coelho, Lísias; Stracieri, Juliana [UNESP]; Ferreira Júnior, João Batista [UNESP]; Tebaldi, Nilvanira DonizeteMade available in DSpace on 2022-04-29T07:26:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-07-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); The most effective disease management method for yield reducing diseases affecting tomatoes is the use of fungicides. This study evaluated the efficacy of chemical control on three Phytophthora sp. isolates, pathogenic to tomatoes. Th...
Selection of biofortified mini lettuce progenies resistant to Pectobacterium ca...
Jacinto, Ana Carolina Pires; Castoldi, Renata; Silva, Isadora Gonçalves da; Mota, Diesiele Caroline Silveira; Moreira, Leticia GonçalvesBrazilian consumers are increasingly seeking unique vegetable products, such as mini lettuces. However, their production is hampered by a wide variety of pathogens, including Pectobacterium carotovorum subsp. carotovorum, which causes soft rot in lettuce. In this study, we aimed to select biofortified mini lettuce genotypes with good agronomic traits and resistance to P. carotovorum. A randomized block design c...
Diversity of Pectobacterium strains by biochemical, physiological, and molecula...
Silva, Adelaide Siqueira; Luz, José Magno Queiroz; Tebaldi, Nilvanira Donizete; Morais, Tâmara Prado dePectobacterium is a complex taxon of strains with diverse characteristics. It comprises several genera, including Erwinia, Brenneria, Pectobacterium, Dickeya, and Pantoea. Pectobacterium and Dickeya cause diseases in a wide range of plants, including potatoes, where they are causative agents of soft rot in tubers and blackleg in field-grown plants. Characterizing Pectobacterium species allows for the analysis o...
Chemical control of phytophthora wilt in tomatoes
Mendonça, Laís Barbosa Prazeres; Coelho, Lísias; Stracieri, Juliana; Ferreira, João Batista; Tebaldi, Nilvanira DonizeteThe most effective disease management method for yield reducing diseases affecting tomatoes is the use of fungicides. This study evaluated the efficacy of chemical control on three Phytophthora sp. isolates, pathogenic to tomatoes. The effect of fungicides on mycelial growth of Phytophthora sp. and on tomato wilt was evaluated in vitro and in vivo. Two tests were done in Petri plates, and one on seedlings, in c...
Occurrence and diversity of Ralstonia solanacearum populations in Brazil
Morais, Tâmara Prado; Lopes, Carlos Alberto; Tebaldi, Nilvanira Donizete; Luz, José Magno QueirozRalstonia solanacearum is a gram-negative soil-borne bacterium capable of infection of hundreds of vegetable species over more than 50 botanical families, causing bacterial wilt, except for bananas, when the disease is called Moko. It deserves special attention, from all other plant pathogenic bacteria, for its high phenotypic and genotypic plasticity, a characteristic that makes disease control extremely diffi...
