ORTHO DIBROM
Fly Spray
If you’re sick anti fired of fooling around with
weak, half-hearted fly sprays, then you’re ready
for DIBROM. Minutes after you spray, every fly
that’s been hit will be dead or dying. When DI-
BROM hits ’em, they stay hit. Even if they’re re-
sistant to other sprays
DIBROM is registered to spray over and around
cattle. In fact, Dibrom in emulsified form is even
safe to spray on food crops, up to four days of
harvest
It’s easy to use, comes to
you ready-mixed and gives
you real economy. Sure, it
costs a little more than
your pyrethrin sprays, but
you’ll find that it gives a
lot better kill. So when all
is said and done you wind
up getting back a lot more
of the money that flies
have been costing you in
reduced milk and meat
production.
Come in and see us . . .
we’ll be glad to show you
how to go after flies like

Based on their semen eval
uations. the scientists divided
the bulls into “good” and
“poor" groups. Within 3 days
of the last evaluation, these
bulls were mated to feedlot
heifers. Results of natural
matings and of the semen
quality tests were consistent
in comparing groups of bulls.
One group of 10 “good” bulls
successfully bred 67 percent
of the heifers to which they
were mated A gioup of 5
“poor” bulls demonstrated

place them close together with
a large plastic bag over them.
Tuck the bag under the pots
so the plants are complete*

This procedure keeps the
plants in a humid atmosphere
and prevents water evapora*
tion from the soil.
The plastic-covered plants
must not be placed in the sun,
Dunham warns. They would
bake to death. Instead, put the
plants away from the sun or
in the basement.
There may be a few yel

when you return home. But
with normal care, they will
soon recover.
