Book Description
Excerpt from On the Nature and Control of the White Pine Blister Rust On the other hand I not only put up the. Theory that these pycnidial drops serve a purpose, but also showed that they have nothing to do directly with the life circuit of the rust fungus, since they occur both early in the spring or they may occur apparently at almost any season in late sum mer and fall (f. B. 742, p. I showed that as the fungus disease is in' summer admittedly absent from pines, the or igin of pycnidial drops with immense numbers of tiny sporebodies (p. 11) occurring during summer and fall on pine cannot be ascribed to the rust fungus, I having originally specifically pointed out that there are then no teliospores present to produce them, since these only occur in the fall.

Book Description
Excerpt from White Pine Blister Rust Control in the Northwestern Region: January 1 to December 31, 1946 Methods. Ammonium.sulfamate and 2,4 d in their respective fields replaced Ktlacide in the treatment of ribes in stream type. Ammonium sulfamate is effective on both Ribes p_tiolare and R. Lacustre which often occur to gether. Its use in such situations cuts labor costs about 50 per cent since the job is done in one Operation, whereas only R. Petiolare was killed with Atlacide, and R. Lacustre had to be pul ed by hand. Whar er. Petiolare occurs alone, -d is used, costing only 2 cents per gallon as against about 14 cents for other chemicals. Where chemical must be back-packed into remote areas, substantial labor savings are made since the amount of -d required of other chemicals necessary to do the'same job. With the new developments in chemicals, power spraying equipment, has been tested for extending this method-of ribes eradication to upland areas. Four-power units have been secured and are being mounted lower on the trucks to increase maneuverability in mountain.
