Spraying Experiments in Nebraska

Bordeaux injury is most severe during wet weather and on 
young fruit. 
Lime sulphur injury is most severe during dry weather. 
The 3-3-50 Bordeaux has proven as efficient for spraying 
apples as any other formula. 
Bordeaux injury cannot be materially reduced by using an 
excess of lime or by applying lime after spraying with Bordeaux. 
HOME BOILED VS. COMMERCIAL LIME SULPHUR 
The comparatively high cost of commercial lime sulphur has 
induced a number of growers to attempt to manufacture their 
own solution. Such varying degrees of success have accompanied 
these efforts that it was decided to conduct a series of tests to 
determine the relative value of the two solutions. Only one 
year's work is reported.

Plat 1 was sprayel four times with home boiled lime sulphur, 1.009 specific gravity. 
Plat 2 was sprayed four times with commercial lime sulphur made up to the same strength. 
iThese trees stood close to check trees which were heavily scabbed. 
Altho the evidence in table 48 is not conclusive, it at least indi- 
cates that the home boiled product is as effective when properly
