The results of two years’ work with these materials seem to show 
that some dry sulfur compounds, if used at sufficient strength, are ef- 
fective in controlling the San Jose scale. From the results of the past 
season where Martin-Senour’s dry lime-sulfur was used at a strength 
of 12% lbs. to 50 gallons of water, it is apparent that these materials 
should not be used at a less rate than 15 lbs. to 50 gallons of water.
