FUNGICIDE, ROW WIDTHS AND PLANT DENSITIES AFFECTING WHITE MOLD INTENSITY

摘要

White mould caused by Sclerotinia sclerotiorum has increased on irrigated bean in the past 10 years in Brazil, especially during the fall-winter growing season. Low temperature, high humidity and plant canopy and/or soil surface wetting favour diseaseprogress. Therefore, wider row and/or plant spacing may provide less favourable environmental conditions due to better light penetration into plant canopy and soil, and more ventilation. The objective of this research was to study the implementation ofcombined strategies against white mould, which included plant density adjustments and fungicide application.
