they cannot he brought Thoroughly
under his control until insect life Is
better understood. Unable to identity
these friends or to understand theF
operations, man too often treats them
as enemies or minimiZes their HIS
sion.
Birds as factors in insect control
should be recognized. 1t Is not I'M
common to find large numbers OF BIRDS
doing very effective work IN con-
trolling insect outbreaks.
Insecticides are substances which
kill insects. Fungicides are substances
which destroy fungous diseases. When
insects and fungous diseases prevail
| upon the same plants insecticides ana
fungicides may be combined and the
two results gained from one appllca-
ton. Variable results have been Cd
tanned from the use of insecticides ana
fupgicides due largely to climatic con-
ditions and to the quality, age and
preparation of the ingredients useu
and the combinations made. A knowl-
edge of the pest being treated and the
nature of the plant infested is an i'm
portant consideration.
Spraying has passed the expert
mental stage and is practiced by all
up-to-date gardeners and fruit grow
ers. The grower should know the
common diseases and insects that az
| feet his plants. should know their
habits and life history. so as to know
what treatment to use and at what
| stage in the life of the organism. TOO
much emphasis cannot be placed upon
the necessity of doing the work at
the right time with the proper solu'
ton and with thoroughness of appli'
cation.
The most successful applications for
plant diseases are made before the
diseases appear because the rene
dies are preventives rather thar
cures. The vegetative portion of the
fungus producing the disease grows
within the tissue of the host plant ant
cannot be reached after it has OBJ
tanned a foothold. Proper application
of fungicide will, however, proven
the spread of the disease to othe
plants. The best tine to spray TO
diseases. therefore, is about the tim
the spores are ripening and being dis
tributed.
There are two general classes Q

Bacterial diseases are those caused b
