“…Tu (1997) recorded that the greater plant population densities and smaller spacing contributed to an increased intensity of white mold, increasing premature senescence and contact between plants, which increasing of the disease incidence in the field. Therefore, the obtained results in this study agree with those found in literature where the intensity of white mold increases in dense plantings compared with more widely spaced plantings (Charchar et al, 1991;Park, 1993;Saidon et al, 1993;Paula Júnior et al, 2009;Macena et al, 2011).…”

White mold (Sclerotinia sclerotiorum) is a major problem of the common bean in Brazil. Thus, the objective of this study was to verify the effectiveness of chemical fungicides and biological products (Trichoderma spp) for the control of white mold in a bean field with different plant population densities located in the Silvânia, Goiás State, Brazil, in the 2007/08 rain season. The experimental design was the randomized blocks, with four replicates and seven treatments. The treatments are consisting of two levels of plant population densities (240 and 120 thousand plants/ha^-1), chemical fungicides (carboxin-thiram and procymidone) and biological fungicides (Trichoderma spp), as well as untreated control. The results indicated that there was no significant interaction between bean population densities and chemical and biological fungicides applied to control S. sclerotiorum. The biological agent Trichoderma spp. is not effective in controlling S. sclerotiorum in common bean crop grown in the Brazilian “cerrado” region. Application of carboxin-thiram + procymidone was the most efficient treatment for the control of white mold on the common bean. Lower planting density is recommended for areas contaminated with S. sclerotiorum, as it can be easily associated with other control strategies.

“…On the other hand, Macena et al (2011) observed that the largest two spacings between common bean rows, from the three tested (20, 40 and 60 cm), promoted a significant reduction in the number of sclerotia of S. sclerotiorum, incidence and severity of white mold, in an area with history of the disease. …”

A B S T R A C TDue to the socioeconomic importance of common bean in Brazil, studies that allow establishing favorable conditions for not compromising the crop with white mold, in view of the enormous damages caused by this fungus, become vital to Brazilian agriculture. Therefore, the aim of this study was to evaluate the incidence and severity of white mold in common bean (Phaseolus vulgaris L.), cultivar 'Madrepérola' , subjected to different irrigation intervals, planting densities and fungicide application. The research was conducted in Viçosa-MG, Brazil, in the years 2011 and 2012. The statistical analysis used the splitsplit-plot scheme. The fungicide applications (with or without fungicide) were allocated to plots, the irrigation intervals (3, 6, 9 and 12 days) to sub-plots and planting densities (6, 9, 12 and 15 plants per linear meter) to sub-subplots, in a randomized block design with three replicates. The variation of the irrigation intervals did not contribute significantly to the control of white mold. It is recommended to use lower planting densities in order to minimize the damages caused by the disease. The use of the fungicide was the main method of white mold control in two consecutive years.Incidência e severidade do mofo-branco no feijoeiro submetido a diferentes tratos culturais R E S U M O Devido à importância socioeconômica do feijoeiro no Brasil, estudos que permitem estabelecer condições favoráveis ao não comprometimento da lavoura com o mofo-branco tornam-se vitais para a agricultura brasileira, haja vista os enormes prejuízos causados por este fungo, , razão por que se objetivou, neste trabalho, avaliar a incidência e severidade do mofo-branco na cultura do feijoeiro-comum (Phaseolus vulgaris L.), cultivar Madrepérola, submetido a diferentes turnos de rega, densidades de plantio e aplicação de fungicida. A pesquisa foi conduzida em Viçosa, nos anos 2011 e 2012. Na análise estatística foi utilizado o esquema de parcelas sub-subdivididas. Nas parcelas foi alocado o efeito do fungicida (com ou sem fungicida), nas subparcelas os turnos de rega (3, 6, 9 e 12 dias) e nas sub-subparcelas as densidades de plantio (6, 9, 12 e 15 plantas por metro linear), no delineamento experimental em blocos casualizados, com três repetições. A variação do turno de rega não colaborou significativamente para o controle do mofo-branco. Recomenda-se a utilização de menores densidades de plantio a fim de minimizar os danos ocasionados pela doença. A utilização do fungicida foi o principal método de controle do mofo-branco nos dois anos consecutivos.
