Severe rusting of the current year's foliage was observed in Drayton Township near Sioux Lookout and in Ignace Township near Ignace in the Sioux Lookout District, in stands along Highway 17 in Ewart and Mac- Nicol townships and at Mileage 29 on the Jones Road in the Kenora District; in Sifton Township north of Stratton and near Williamson Lake north of Atikokan in the Fort Frances District (Table 6).

Seav. This foliage disease caused browning of foliage on trembling aspen trees along the Ignace-Pickle Lake road 10 miles south of Rat Rapids on Lake St. Joseph (see photograph). Light infection was observed at one point elsewhere in Sioux Lookout District, at three points in the Kenora District and at one point in the Fort Frances District. Hypoxylon Canker of Poplar, Hypoxylon pruinatum (Klotsche) Cke. This pathogen was found in most aspen stands throughout the region and was most prevalent in stands on poor sites (see photograph). Examination of permanent sample plots at ten points showed that light tree mortality occurred in one sample plot in. the Sioux Lookout District and in four plots in the Fort Frances District. No change occurred in the status of the disease at sample plots in the Kenora District (Table 7).
