The bean cultivar Pérola was grown in Central Pivot (winter crop season [dry], 2015) in the Farm São José, Cristalina, Goiás State, Brazil. Nine types of treatments represented by fungicides and biological control agents were used in four applications conducted in six blocks (RBD), totaling 54 experimental units. In the experimental area, the spatial distribution of the inoculum was evaluated under the influence of the treatments 39 days after planting (DAP), 46 DAP, 53 DAP, 60 DAP, 67 DAP and 74 DAP. For this study, the incidence of white mold (% IWM) was evaluated in the quadrants (36 m2), and the area under the disease progress curve (AUDPC) was calculated, as well as productivity (P) at 83 DAP. Values of % IWM, AUDPC and P were arranged in matrices X (m), Y (m) and Z (%) for the elaboration of distribution maps. In both vegetative cycle and reproductive cycle of the crop, the disease incidence foci changed their spatial position and randomly increased the myceliogenic and carpogenic incidence in the evaluated area. The use of sanitary measures for white mold control influences the dynamic of the dispersion of white mold in bean plants.</p><p></p> 2019-02-06 02:41:39 white mold spatial dispersion incidence myceliogenic cycle carpogenic cycle
