Abstract Not Available – First paragraph follows:
Russet of Bartlett pears was not increased by the cluster-bud spray or bloom period dusts applied in test orchards during the spring of 1956.
The studies concerning the comparison of streptomycin, copper, and no blight-control treatment were made in plots in which Peter Ark, Professor of Plant Pathology, University of California, Berkeley, conducted blight-control experiments with streptomycin-pyrophyllite.
