摘要: A method for evaluating the potential threat of selection resistance to organically-based fungicides in populations P. viticola is needed screen a large panel products alternative copper organic viticulture. Populations from an unexposed plot were compared throughout one season with population sprayed azoxystrobin (Quadris), reported as engendering pressure and resistance, fungicide (Mycosan). The evolution three was followed neutral specific SSR markers marker strobilurin control resistant mutants. reduction genetic diversity observed azoxystrobin, consistent directional toward higher confirmed by enhanced frequency mutants respect population. In contrast, reduced fungicide. Assessing genotypic allows detection constitutes valid instrument screening non-specific, different possibly indirect modes action.
