A FEW ORCHARD PLANT LICE 
miscible oils 
There are several miscible oils upon the market which 
may be added directly to water forming a milky emul¬ 
sion at once. In the preparation of any of these, such as ‘‘Scale- 
cide,” ‘‘Target Brand Scale Destroyer” or “Killoscale” add the 
oil directly to the water with a little stirring. One gallon of the 
miscible oil in fifty gallons of water will make a two per cent, mix¬ 
ture, which in most cases, should be strong enough to kill plant 
lice if thoroughly applied.

LIME-SULPHUR MIXTURE 
OF SUM=WR, PIFTEtN FOUNDS 
Good lump lime, hfteen pounds. Water, forty-five gallons. 
This is the 1-1-3 lime-sulfur mixture. First slake the lump 
lime with sufficient warm water, and while still boiling hot, add 
the sulfur and stir it in. Place over the fire and continue the boil¬ 
ing, adding water when necessary, until the mixture changes to a 
deep reddish brown color which indicates that the lime has cut the 
sulfur. It will be necessary to boil steadily for about forty minutes 
to one hour to produce this result. The mixture should then be 
diluted to form forty-five gallons of the spray, and should be applied 
at once. 
When the lime-sulfur mixture is placed in the barrel or tank 
it should be strained through gunny sacking to take out all lumps 
that would clog the spray nozzle. If allowed to stand for any great 
length of time after being prepared, the lime sulfur crystalizes out 
to a considerable extent. In such a case it is necessary to heat the 
mixture again before applying so as to dissolve all the crystals. 
If the crystals are re-dissolved the mixture will be as strong as 
before. 
To make 1-1-2 lime-sulfur mixture, prepare as above using 
only thirt}^ gallons of water for the fifteen pounds of lime and the 
fifteen pounds of sulfur. 
For the 1-1-4 lime-sulfur mixture prepare in the same manner, 
but dilute to sixty gallons before applying. 
REX lime-sulfur 
We have found the Rex lime-sulfur in the proportion one 
gallon of the Rex to seven or eight gallons of water to be just 
about equal in effect to the 1-1-3 home made lime sulfur preparation. 
WHALE-OIL OR FISH-OIL SOAPS 
The so-called Whale-oil or fish-oil soaps which are quite ex¬ 
tensively used for the destruction of plant lice will usually be effec¬ 
tive if thoroughly applied in the proportion of one pound of the 
soap to each six or eight gallons of water. There are numerous 
brands of these soaps upon the market. Those that we have used 
successfully are Good’s Whale Oil Soap and Bowker’s Tree Soap.
