UMOID AND KEROSENE. 
During the past few months The R. 
N.-Y. has had considerable to say about 
the K.-L. mixtures—brought to notice by 
Prof. C. P. Close, of the Delaware Sta¬ 
tion at Newark. A year ago we gave 
the experience of Win. Dickson, but Prof. 
Close is entitled to the credit for working 
out the details of this promising insecti¬ 
cide. Lack of space prevents our giving 
full details here. These will be found 
in a bulletin soon to be issued by Prof. 
Close. 
In brief, the K.-L. insecticides are 
formed by mixing limoid with kerosene. 
“Limoid” is a dry, slaked magnesium 
lime stone, ground into a very fine pow¬ 
der. There appears to be no chemical 
action when kerosene is mixed with the 
limoid, but the limoid takes up the kero¬ 
sene and holds it firmly so that when 
sprayed upon a tree the oil is retained. 
We all understand that kerosene is de¬ 
structive to many forms of insect life. 
'I'he danger in using pure kerosene is 
that it often injures or kills the tree, or 
the buds and leaves. The sprayers which 
are supposed to throw a mechanical mix¬ 
ture of kerosene and water do not always 
operate properly, and the oil evaporates 
rapidly. The same is true to a less ex¬ 
tent of kerosene emulsion. The object 
in using the limoid is to put the kero¬ 
sene evenly over the tree in such strength 
that it will not be injurious, and still 
stick until its work is done. This limoid 
was used in making the “cold water 
paints” which were sold some years ago, 
so that we can realize how it will hold 
the kerosene up to its work. 
Preparing the K.-L. mixture is easy 
compared with making or spraying lime 
salt and sulphur. The accompanying pic¬ 
ture shows Prof. Close and his assist¬ 
ant mixing the materials. To make a to 
per cent mixture pour 2 / gallons or 
10 quarts of kerosene into the barrel and 
add to pounds of limoid. Mix them well 
together with a paddle or hoe, and if 
need be, add enough limoid to take up all 
the free oil which rises to the top. Then 
add water and keep the mass thoroughly 
stirred up. The total amount of water 
required is 22 / gallons or 00 quarts. 
The kerosene and the water added to¬ 
gether make too quarts, with one pound 
of limoid to each quart of kerosene. A 
20 per cent mixture would lie 20 quarts 
kerosene and so quarts water with 20 
pounds of limoid—and so on. It is ab¬ 
solutely necessary that the limoid be 
thoroughly mixed with the kerosene. 
Otherwise there will be more or less free 
kerosene sprayed out—to the injury of the 
trees. If the mixing is thoroughly done 
every spoonful of the limoid will carry 
its true proportion of kerosene. The 
picture shows how Prof. Close mixes 
the materials. A pump with its agitator 
is put down into the liquid with the hose 
running back into the barrel. Five min¬ 
utes hard pumping of the liquid out of 
the barrel and back stirs it up thoroughly. 
We have done this work by churning the 
liquid with a wire handle like a churn 
dasher, but the pump is much better. The 
mixture is sprayed in the usual way, 
requiring much the same power as lime 
and sulphur. The limoid is also used 
in making Bordeaux Mixture, or with 
Paris-green, but we advise a trial of 
the K.-L. mixture alone. Ten and possi¬ 
bly 12 '/ per cent mixtures can be used 
in Summer, but for a trial we advise a 
20 per cent mixture the latter part of 
March in this latitude, or when lime 
and sulphur would naturally be used. 
Fhe cut on the right shows a peach tree 
sprayed with K.-L. 
One should be conservative in advising 
the use of a new insecticide, but the K.-L. 
mixture certainly seems worth a trial. 
Prof. Close’s experiments are very en¬ 
couraging. He gives the following state¬ 
ment of advantages of the K.-L. mixtures: 
They are easily made without any heating 
of materials; are moderate in cost; are not 
disagreeable to handle except when caustic 
soda is used; have no unpleasant odor; 
can be sprayed through the finest kind of 
nozzle without clogging if foreign matter is 
kept out : do not necessarily require strain¬ 
ing: are effective and adhere well : can lie ap¬ 
plied at any lime during the year: are ab¬ 
solutely uniform in percentage of kerosene: 
can lie used against all sucking insects, and 
we hope against biting insects and fungus 
diseases also, all in one application; and can 
lie distinctly seen on I lie irees so a careless 
nozzleman can not hide a poor job. Another 
special advantage is the spreading of (lie 
spray on the bark like the spreading of oil 
on paper. This is especially desirable on 
fuzzy twigs like those of the apple. 
Mr. Charles Black, of New Jersey, used 
various spraying mixtures, and sent 
sprayed twigs to Prof. J. B. Smith, of 
New Jersey. Prof. Smith made the fol¬ 
lowing report: 
The result of the examinations made is as 
follows: Lot No. 1, several pear twigs marked 
sprayed November 30 with "Consol”; seven 
twigs were examined and 369 scales were 
tested: of these 122 were alive. Lot No. 2, 
portions of ihree peach branches marked 
caustic soda, sprayed November 23, 12 pounds 
to 50 gallons of water : four twigs were ex¬ 
amined, 156 scales were investigated and 81 
were certainly alive. I.ot No. 3, pear twigs 
marked limoid and 20 per cent kerosene, 
sprayed about November I ; five twigs were 
examined, 269 scales were investigated and 11 
PEACH TREE SPRAYED WITH K.-L. 
of these were alive. Of the 11 five were on 
one twig in one place, and seemed as if they 
had been missed in the application. This 
will probably give you tlie information you 
want and while none of the applications were 
entirely effective, the third, that is. the lim¬ 
oid and kerosene is by all odds the most 
effective of the three. joiin b. smith. 
Mr. Black writes us that he has decided 
to depend on limoid and kerosene alone 
this year.

but a necessity.
