 INSECTS IN THE PLANT BED
 Examine beds closely for insects or insect damage as soon
as plants come up. Apply insecticides as needed. A dust con-
taining 1% parathion and 5% TDE is effective against aphids
(lice), hornworms, budworms, fleabettles and climbing cut-
worms. Apply at the rate of 1 pound per 100 square yards
of plant bed. To control the same insects with a spray use
one of the following combinations:


 Insecticide
50% TDE wettable powder
 or
24% TDE emulsifiable concentrate
 (liquid)
 plus
15% parathion wettable powder
 or
25% malathion wettable powder
 or
40% TEPP emulsifiable concentrate
 (liquid)
Apply 3 to 5 gallons of above spray
yards of bed.

 INSECTS IN THE FIELD
 Cutworms: Cutworms often cause serious damage to tobacco
and they are difficult to control because they migrate over

bait, 5 pounds per acre for hill placement and 15 to 20 pounds
per acre for broadcast application. Apply before setting plants
in the field or immediately when damage is noticed.
 Budworms: Tobacco budworms and occasionally corn ear-
worms are a menace to the crop. They may actually occur
on young seedlings before they are removed from the plant
bed and will continue their activity throughout the growing
season. The common name budworm indicates where the prin-
