Flacherie resists

In 1878, at the Congrès international séricicole, Pasteur admitted that "if pébrine is overcome, flacherie still exerts its ravages". He attributed the persistence of flacherie to the fact that the farmers had not followed his advice.

In 1884, Balbiani, who disregarded the theoretical value of Pasteur's work on silkworm diseases, acknowledged that his practical process had remedied the ravages of pébrine, but added that this result tended to be counterbalanced by the development of flacherie, which was less well known and more difficult to prevent.

Despite Pasteur's success against pébrine, French sericulture had not been saved from damage. (See fr:Sériciculture in the French Wikipedia.)
