“…The existence of variability in the reaction to this pathogen was reported at several occasions (Salgado & Schwartz, 1993;Woo et al, 1996;Sala et al, 2006;Pereira et al, 2008). There are some reports of ge- netic control of resistance; the first was probably the study of Ribeiro & Hagedorn (1979), who identified the presence of only one gene with a dominant allele conferring resistance.…”

Aiming to obtain information concerning the genetic control of the resistance of the bean (Phaseolus vulgaris L.) to the fungus Fusarium oxysporum f. sp. phaseoli, six crosses involving three resistant lines (Carioca MG, Esal 583 and Esal 566) and four susceptible to the fungus (Carioca, CNFC 10443, Uirapuru and Esal 522) were developed. The parental lines, the controls (Carioca MG and Carioca) and the F 1 , F 2 and F 3 generations were evaluated for reaction to Fusarium. For inoculation, root cuttings were immersed in a spore suspension. The evaluations were performed at 21 days after inoculation, by scale of notes ranging from 1.0, to 9.0 and genetic and phenotypic parameters were estimated. The heritability in the narrow sense ranged from 0.34 to 0.42 and in the broad sense of 0.76 to 0.97, showing that selection should be easy, since efficient inoculation and selection methods are used. The average degree of dominance was around 1.0 indicating the presence of dominance in the control of the character, although additive effects are also expressive.

“…They include Bipolaris, which causes foliar diseases in rice (Celmer et al, 2007) and damage in the grass, Paspalum atratum cv. Pojuca (Anjos et al, 2004) and fungi of the genus Fusarium,, which is a disease agent in various hosts (Sala et al, 2006;Dias and Toledo, 1993), including castor bean. In general, the treatment with the biological product did not inhibit the growth of fungus species, including some, such as Fusarium (Silva et al, 2005), which are very important for castor bean, principally the AL Guarany 2002 cultivar (Table 5).…”

“…Fusarium is a soil-inhabiting species and is often found on seeds, causing damage in various crops, such as basil (Reis et al, 2007), black pepper (Carnaúba et al, 2007), dry beans (Sala et al, 2006) and also castor bean, where it can cause severe damage (Silva, 2005). Alternaria is another fungus, associated with castor bean seeds, causing alternaria spot disease (Silva, 2005) and the fungus Macrophomina is responsible for one of the main diseases found in castor bean (stem or root rot) and various other crops via the seeds (Vanzolini et al, 2010).…”

RESUMO -Avaliou-se o efeito dos tratamentos químicos e biológicos sobre a emergência, vigor de plântulas de mamona, produção de matéria seca, além do controle de microrganismos associados às sementes das cultivares AL Guarany 2002 e Lyra. Os produtos testados foram carbendazim+thiram, carboxin+thiram e um à base de Trichoderma. A emergência total e de plântulas foram avaliadas aos 27 dias após a semeadura e a produção de matéria seca, com plantas retiradas 45 dias após a semeadura. A cv. AL Guarany 2002 apresentou maior incidência de microrganismos em relação à cv. Lyra. O tratamento químico foi 100% eficiente no controle de fungos e o tratamento biológico não reduziu a incidência de microrganismos nas sementes. O tratamento químico resultou em plantas com maior matéria seca e os melhores resultados foram para carbendazim + thiram e carboxin+ thiram, nas doses de 60 g + 140 g e 50 g + 50 g/100 kg de sementes, respectivamente. O carbendazim + thiram foi o único tratamento que se mostrou estatisticamente superior, quanto ao índice de emergência total, enquanto que o tratamento biológico aumentou os valores de emergência somente na cv. Lyra, evidenciando sua inferioridade. Destacou-se a importância dos fungicidas para o controle de patógenos associados às sementes.Termos para indexação: Ricinus communis, fungicidas, teste de papel filtro, Trichoderma.ABSTRACT -The effect of chemical and biological treatments on castor bean emergence, seedling vigor, dry matter production, and also the control of microorganisms associated with seeds of the AL Guarany 2002 and Lyra cultivars, was evaluated. The products tested were carbendazim + thiram, carboxin + thiram and a product based on Trichoderma. Total seed and seedling emergence were evaluated at 27 days after sowing whereas dry matter production was verified for plants removed 45 days after sowing. The Guarany 2002 AL cultivar had a higher incidence of microorganisms than the Lyra cultivar. The chemical treatment was 100% effective in controlling fungi but the biological treatment did not reduce microorganism incidence on the seeds. Chemical treatment resulted in plants with more dry matter and the best results were for carbendazim + thiram and carboxin + thiram at doses of 60 g + 140 g and 50 g + 50 g/100 kg of seeds, respectively. The carbendazim + thiram mixture was the only treatment which was statistically higher for total emergence whereas the biological treatment increased emergence only for the Lyra cultivar, thus demonstrating its lower efficiency. The importance of fungicides to control pathogens associated with seeds was discussed.

“…A resistência a múltiplas raças de F. oxysporum f. sp. phaseoli foi citada por Sala (2006), que avaliou 104 genótipos que apresentaram 33% de resistência às raças 1, 2, 3 e 4 do patógeno. Silva et al (2009) avaliaram 56 cultivares de feijoeiro quanto à resistência ao crestamento bacteriano e encontraram 37% dos genótipos com resistência ao patógeno.…”

Resumo:O objetivo deste trabalho foi avaliar a resistência de genótipos de feijoeiro aos principais patógenos da cultura, bem como a adaptabilidade e a estabilidade de produção de grãos desses genótipos. Avaliaram-se 26 genótipos de feijoeiro quanto à resistência a Colletotrichum lindemuthianum, Fusarium oxysporum f. sp. phaseolie Xanthomonas axonopodis pv. phaseoli, por meio de inoculação, em laboratório, e em 19 ensaios de valor de cultivo e uso (VCU), em diferentes locais do Estado de São Paulo, nas safras das "águas", "seca" e "inverno", durante os anos agrícolas 2011, 2012 e 2013. Dezoito genótipos foram considerados resistentes: sete deles a C. lindemuthianum, sete a F. oxysporumf. sp. phaseolie quatro a X. axonopodispv. phaseoli. A reação de resistência aos patógenos está associada à estabilidade dos genótipos. Por meio das análises GGE biplot, foi possível identificar genótipos com adaptabilidade e estabilidade superiores às das testemunhas, nos dois grupos de tegumento avaliados, em todas as épocas de semeadura.
