-37- 3.3 TREE DISEASE CONDITIONS 3.3.1 Western Gall Rust, Peridermium harknessii J. P. Moore:- This gall rust was common in jack pine stands near Richer, Marchand, Woodridge, Piney, Sprague, and Moose Lake in southern Manitoba. Infection was generally light with an occasional tree moderately attacked in the Moose Lake area where fruiting was common by May 30. Light infection also occurred along the Bear River Road, north of Pine Falls, at Aikens, Charron, and Weaver lakes, and throughout the Belair Forest Reserve. North of Stead in the Belair Forest Reserve 7 out of 20 trees examined were infected and fruiting galls were common by June 3. Jack pine stands at Stevenson lake in the northern District were lightly infected with severe infection on an occasional tree. 3.3.2 'A Needle Rust on Spruce, Chrysomyxa sp.:- A light infection was recorded on the foliage of black spruce 9 miles north of Pine Falls, and a moderate to severe one at Pointe du Bois. The latter affected several acres and ranged from moderate to severe on reproduction to light on large trees. 3.3.3 White-pine Blister Rust, Cronartium ribicola, Fischer:- Little change was apparent in the status of this blister rust and flagging was common on white pine northeast of Moose Lake. 3.3.4 Dwarf Mistletoe of Black Spruce, Arceuthobium pusillum Peck:- Occasional brooming of black spruce was noted along the north shore of Brereton Lake and throughout the area north of Pine Falls to the O'Hanley River. Moderate to severe attack occurred in the Belair Forest Reserve north of Stead and east of Grand Beach. In southern Manitoba, infections occurred from Hadashville to Dawson Cabin, south of East Braintree in the Birch Lake area, and from Moose. Lake to Sprague Lake in the Northwest Angle Forest Reserve. 3.3.5 Mistletoe of Jack Pine, Arceuthobium americanum, Nutt. ex Engelm:- There was no change in the areas previously affected by this misteltoe and no new ones were found. Severe infections occurred in jack pine stands near Belair and Victoria Beach. The misteltoe plants were examined for the parasite Wallrothiella arceuthobii but it was not found. 3.3.6 Mortality of Balsam fir:- An occasional dead balsam was noted in most stands throughout the District. Scattered, dead trees were recorded east of Great Falls and over a small area north of Aikens Lake where mortality ranged from 5 to 10 percent. Several islands in Sasaginnigak Lake showed tree mortality ranging from 15 to 20 percent and. up to 35 percent on a small island in Eardley Lake. The exact cause of this condition is still not fully understood but it apparently is not due to insects or diseases.
