Abstract

A five year survey was carried out in Italys main pear growing district (eastern Po Valley), both randomily and from orchards having a history with problems in controlling S. vesicarium damage. 167 strains of the fungus were collected over the years and tested for their sensitivity to the dicarboximide procymidone and iprodione.
While the majority of the strains tested resulted sensitive to less then 1 µg active ingredient (a.i.)/ml, 30% of the strains resulted much less sensitive, with EC₅₀ values in the range 1000-5000 µg a.i./ml for procymidone, and greater then 5; up to 30 µg a.i./ml for iprodione.
These results support/explain the difficulty often encountered in controlling the disease in northern Italy.
