Book excerpt: 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.
