TESTS. 
This resin ime mixture with Paris green added was first tested 
in 1895 on elm trees for the elm leaf beetle. The mixture was 
applied but once, about June 10, both sides of the leaves being 
thoroughly sprayed. On August 1 the leaves of the sprayed 
trees were nearly perfect, while those on adjoining unsprayed 
trees consisted principally of veins and midribs to indicate what 
had once been leaves. 
September 13, 1895, the resin lime mixture, with Paris green 
added, was used to spray a patch of rutabagas (smooth leaved, or 
Swedish, turnips). This patch was badly infested with the cab- 
bage worm.® ‘Three days after treatment not a living worm could 
be found on the patch. Although heavy rains followed the spray- 
ing, enough of the mixture adhered to the leaves so that no later 
broods of the worms succeeded in getting a foothold on the sprayed 
plants. 
ON CABBAGE. 
In 1896 two separate tests of the resin lime mixture with Paris 
green were made on cabbage against the cabbage looper and ‘the 
cabbage worm. ‘These tests were carried out on separate farms. 
First test.— The first test was made on medium late cabbage, a 
mixture of Savoy, Flat Dutch, and Red Dutch varieties, part of 
which had commenced to head. For the sake of comparison Bor- 
deaux mixture was used on part of the plats. On August 26 the 
plats were treated as follows: 
Plat 1. Six rows, sprayed with resin lime mixture and Paris green. 
Six rows, check. | 
Plat 2. Six rows, sprayed with Bordeaux mixture.‘ 
Six rows, check. 
6 Throughout this bulletin the term “cabbage worm” is used for “ im- 
ported, or European, cabbage worm” (Pieris rapae) also “ cabbage-looper ”” 
or simply “looper” is used instead of “cabbage Plusia” (Plusia brassicae). 
7 Bordeaux mixture used alone adhered only in the folds of the Savoy 
varieties, but where resin mixture was added it adhered as well as did the 
resin lime mixture.
