1. Resistance to Fusarium wilt in common bean
Abstract In breeding programs, understanding the potential of parents should be a way to spend significantly less time and costs to obtain new cultivars. For this, the objective of this study was to estimate the general and specific combining ability of parents aiming common bean breeding for resistance to Fusarium wilt (FW) based on disease severity and red

2. Classification of physiological races of Fusarium oxysporum f. sp. phaseoli in common bean
Fusarium wilt, caused by Fusarium oxysporum Schlecht. f. phaseoli Kendrick and Snyder (FOP), is a major disease of common bean, causing large economic losses. Genetic resistance is one of the main mechanisms of pathogen control, and knowledge of the physiological variability is fundamental in breeding for resistant cultivars. Thus, a method of pathogen class

3. Screening of lettuce accessions for resistance to Fusarium oxysporum f. sp. lactucae race 1
Fusarium wilt caused by Fusarium oxysporum f. sp. lactucae (FOLAC) is one of the most important problems for lettuce growers because it causes major losses in production. To identify cultivars with potential for use in the management of the disease, 102 accessions were evaluated for resistance to isolates of race 1 of FOLAC. Initially, preliminary screening

4. Resistance of common bean to Fusarium oxysporum f. sp. phaseoli. / ResistÃncia do feijoeiro a Fusarium oxysporum f. sp. phaseoli
The Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli, is a severe vascular disease in the common bean, and occurs in all regions where the common bean is cultivated. The better way of controlling the disease is through the use of resistant cultivars. Three kinds of research were done aiming to get informations for making the breeding pr

5. Evaluation of the acibenzolar-S-methyl, citric extract and bacterial fermented on the control of bacterial wilt (Ralstonia solanacearum) in tomato plants (Lycopersicon esculentum Mill) / AvaliaÃÃo de acibenzolar-s-metil, extrato cÃtrico e fermentado bacteriano no controle da murcha-bacteriana (Ralstonia solanacearum) do tomateiro (Lycopersicon esculentum Mill)
The bacterial wilt caused by Ralstonia solanacearum is one of the main diseases that can reduce the productivity of tomato culture (Lycopersicon esculentum). The control of this pathogen is difficult, since the bacteria overwinter in plant debris, in diseased plants and in the soil. The use of resistance varieties is difficult because it depends on environme

6. Indução de resistência em plantas de berinjela e tomate por Lentinula edodes e Agaricus blazei contra bactérias causadoras de murcha (Ralstonia solanacearum) e cancro (Clavibacter michiganensis subsp. michiganensis) / Induced resistance by Lentinula edodes and Agaricus blazei in tomato plant and eggplant against bacterial wilt (Ralstonia solanacearum) solanacearum) and bacterial canker (Clavibacter michiganensis subsp. michiganensis)
Devido ao aumento da preocupação com o impacto dos agrotóxicos no meio ambiente e na saúde humana, busca-se uma agricultura sustentável. É no âmbito dessa questão que a resistência induzida torna-se uma ferramenta fundamental no manejo integrado de doenças e indispensável para uma nova agricultura, mais racional e sustentável. Dentre os diversos

7. Sintomatologia, etiologia e controle da murcha bacteriana do eucalipto / Symtomatology, etiology, and control of eucalypt bacterial wilt
The eucalypt bacterial wilt caused by Ralstonia solanacearum is important disease, because of systemic infection, of the loss caused, and of the pathosystem characteristics with difficult control. The aims of the work for the pathosystem R. solanacearum-eucalypt were: i) symtomatology descriptions, and loss quantification caused by disease; ii) transmition p

8. The I2C family from the wilt disease resistance locus I2 belongs to the nucleotide binding, leucine-rich repeat superfamily of plant resistance genes.
Characterization of plant resistance genes is an important step in understanding plant defense mechanisms. Fusarium oxysporum f sp lycopersici is the causal agent of a vascular wilt disease in tomato. Genes conferring resistance to plant vascular diseases have yet to be described molecularly. Members of a new multigene family, complex I2C, were isolated by m
