Deskripsi
FIELD EXPERIMENTS to Compare Streptomycin with copper for control of fireblight of pears were conducted on the Natomas Company Ranch, east of Sacramento, under conditions which were compatible with a commercial pear growing operation. This pear ranch was selected for use because of the extensive fireblight present there during 1969. The trees in this 12-year-old Bartlett pear orchard were planted 20 ft by 20 ft (109 trees per acre).
