PISTILLATE FLOWERS TAKEN FROM A KELLOGG PLANT 
r»iTJTiriTT ATI attention is called to the very full development of these three pistillate blooms. It will be seen that the pistil 
tion is used and the old plants are immediately 
destroyed, the species of these insects are not 
liable to increase to any dangerous degree. 
A. L. Lovett, professor of entomology in the 
Oregon State College, says in one of his articles 
that strawberry fields do not generally begin to 
show the attack of these insects until the beginnmg 
of the third fruiting season, and that plants which 
are grown in hills will not become infested as soon 
as those grown by the matted-row system. He 
also says that adult insects cannot fly, and, there- 
fore, it goes without saying, these insects must 
be carried to your farm by taking plants from in- 
fested fields. 
C. M. Weed, professor of entomology in the 
New Hampshire College of Agriculture, another 
authority on insects says in his book, "Insects 
and Insecticides," 
(see page 138) that 
these insects are 
the most destruc- 
tive enemies to the 
strawberry; that 
the adults of the 
crown borer and 
such insects are 
unable to fly from 
field to field, and 
that the only way 
these insects may 
reach your farm is 
by getting plants 
which have been 
infested with 
them. These in- 
sects are especially 
liable, he says, to 
injure old straw- 
berry fields or 
those which are re- 
planted without 
some intervening 
crop. 
During the past 
season we have vis- 
ited many straw- 
berry sections of the Far West, where the grow- 
ers have been fruiting fields of plants from three 
to ten years without any rotation of crops, and 
when they set their new fields plants were taken 
either from their own fruiting beds or from those 
of their neighbors. And in these districts we 
found many fields of plants absolutely in the con- 
trol of these insects. In these same districts we 
found growers, who allowed their fields to fruit 
two years only, who purchased plants which were 
entirely free from any insects of this kind, and 
who were now growing many more berries per 
acre and fruit of higher quality than they did when 
they started in the business. 
We have been growing strawberry plants for 
nearly thirty years, and never allow any field 
of plants to fruit more than two crops. We fol- 
low the rotation 
system, and never 
have found one of 
these insects upon 
our farms. W e 
have our farm di- 
vided into two sec- 
tions ; one-half 
growing straw- 
berry plants for 
this year's trade; 
the other half 
growing a legumi- 
nous crop and being 
prepared f orplants 
the following year. 
This gives us what 
may be practically 
called new soil for 
plants every year. 
If growers will use 
the Kellogg Thor- 
ughbred Pedigree 
plants and follow 
the rotation sys- 
tem, allowing no 
field to fruit more 
than two years,

WEAKENED BI SEXUAL FLOWERS 
THESE flowers were taken from common plants that were shipped to us. 
They have been weakened by pollen-secretion and seed-production. Note 
the few and weak anthers which are unevenly developed around the pistU 
cone In fact there are only nine or ten anthers on each flower, and these are 
inunature. This explains why plants which are propagated without regard 
to selection can not be depended upon to give satisfactory crops of berries. 
As some growers describe the situation, the plants are run out." Could any- 
thing illustrate more clearly the reason why growers should never take plants 
from a fruiting bed. or try to grow i>lants and fruit from the same mother 
plants, or to set any but the very best quality plants available? Wo think not.
