Excerpt from Report on White Pine Blister Rust Control, 1918 The Fifth Annual International Blister Rust Conference was held at Albany, New York on December 8 - 9, under the auspices Of the American Plant Pest Committee. Foresters and pathologists representing the New England States, New York, Pennsylvania, Wisconsin, Minnesota, and Canada were present. The sessions were full of interest, and left no doubt that practical and effective measures for the control of white pine blister rust have been developed during the past four years Of experimental work.

Excerpt from White Pine Blister Rust Control in the Northwestern Region: January 1 to December 31, 1948 Inland.empire was conducted on all forests. Information was also secured on which to base predictions on future white pine losses to blister rust according to number of years elapsing without control being established. About miles of etri 'wer su vey and the final results showed that the white pine in the ri a een reduced by'a 25 per cent loss from blister rust.

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.
