is impractical to destroy in any other manaer. When necessary to 
adopt this practice, an attempt should be made to plow under ALL 
of the material to a depth of at least 6 inches. 
Plant small areas of early sweet corn to act as a trap crop adjacent 
to the fields intended for field corn or late sweet corn. Feed or other- 
wise destroy this early sweet corn as soon as the ears are harvested, 
or preferably just before that period, if the grower is willing 
to sacrifice the ears. Such plantings, where not destroyed at the 
proper time, constitute a menace to later corn. 
Limit the size of cornfields to areas that can be kept free of weeds. 
Do not plant corn within 50 feet of beets, beans, celery, spinach, 
rhubarb, or flowering plants intended for sale. 
Do not throw the uneaten parts of cornstalks used as feed or bed- 
ding into the manure pile unless this material is worked into piles 
containing enough fresh horse manure to produce heating. 
Do not transport outside of the infested area any of the plants or 
plant products listed on page 32. 
Do not transport alive, in any of its stages, specimens of the 
European corn borer outside of the infested areas. 
Do not place in swill container any sweet-corn ears or portions 
thereof, or discarded portions of celery, beets, beans, rhubarb, and 
spinach when this material is suspected of containing the borer. 
Do not dump cornstalks or other plant refuse from the vegetable 
and flower garden on public dumps or on the edge or flood level of 
brooks, rivers, and other bodies of water. 
Do not attempt to circumvent the quarantine regulations. The 
penalty is severe. 
Do not mix products grown within the infested area with those 
grown outside the infested area. 
Do not label packages containing flowers or other products with 
misleading statements of contents. 
Do not pack produce in boxes or other containers until all old 
tags and permits have been removed. 1 
Do not feel angry if products are confiscated at State or inter- 
national border lines for violation of quarantine regulations. Such 
action is the most lenient that may be taken under the law.
