Defects of Stanley Prune in Idaho

Abstract

In 1955 the occurrence of Iopsidedness in Stanley prunes (Figure 1) was observed in many plantings of that variety in the irrigated fruit districts of Idaho and Washington. It was seen also under dry-land conditions at Moscow, Idaho. In a four-year-old, six-arcre block at Emmett, Idaho, an estimated 65 percent of the fruit was deformed and the crop was a total loss, as neither the local packing house nor the local cannery would accept the fruit because of the severe cullage that would have been necessary
