Summary

The results both in upstate New York with Rural potatoes and un Long Island with Green Mountains seem to consistently favor a Bordeaux mixture with less lime than copper sulfate.

In one experiment at Pittsford in which the amount applied was also varied, there seemed to be a clear indication that with mixture, not so much copper per acre is necessary to give maximum yields as with mixtures containing larger proportions of lime.

So far as our experience goes in these three years in the three localities, it appears safe and desirable to reduce the lime in the mixture, either stone or hydrated, at least to half as much as the amount of copper sulfate.
