SUGGESTIONS FOR CONSTRUCTION OF PLUNGING AND GROWING BEDS
AND THEIR MAINTENANCE UNDER BEETLE-FREE CONDITIONS
IN ACCORDANCE WITH REGULATIONS OF THE WHITE-
FRINGED BEETLE QUARANTINE


Nursery stock with soil attached is eligible for certification

for movement from areas under quarantine on account of the white-

fringed beetle, provided it has been grown and maintained under

beetle-free conditions,, or has been otherwise treated, as speli-

fied in paragraph (b) of regulation 5 of Quarantine No 72,

The Bureau of Entomology and Plant Quarantine and cooperating

State officials are attempting to reduce beetle populations as

drastically as possible in all infested areas by the application of

intensive control measures in the vicinity of nurseries and other

establishments dealing in regulated products However, unless or

until eradication is accomplished, such suppressive measures within

themselves do not and cannot adequately protect nurseries or other

establishments within a generally infested area from being exposed

to infestation, and additional action on the part of the nurseryman

is necessary.

In order to establish and maintain an infestation-free status in

nurseries or units of nurseries located within a generally infested

area. approved beetle proof barriers must be constructed by the nursery-

men to protect plunging beds and growing a'ea .- nd adequate sanitary







-2-


and protective measures must be taken to maintain such barriers

in an effective status, Barriers must be supplemented by precautionary

measures against the artificial introduction of beetles into such

protected areas and insecticidal treatments as specified by author-

ized inspectors should be applied

B. E. P. Q. 496, issued April 28 1959., provided information

on the construction of barriers approved at that time Subsequent

research indicates that barriers of a less expensive construction

will furnish adequate protection. The following types of units

and barriers are therefore suggested as a means of providing pro-

tection against natural infestation by the white fringed beetle,


Raised Plunging or Growing Beds

Beds or benches' indoors or outside must be used. which are

at least 12, preferably 18 inches, aoove the ground, the legs or

supports of which are protected by approved oil or other barriers,

and which are maintained in a manner satisfactory to an authorized

inspector, These structures are illustrated in the accompanying

plates 1 and 2.

Growing Beds Including Entire Nurseries or Portions Thereof

Heeling-in'or'growing areas should be enclosed within approved

barriers Construction details for such barriers are given in plates

3 and 4.o The areas contained therein must, at the time of erection

of barrier, be known to be free of infestation or must be treated

in approved manner under the supervision of an inspector,

No plants with soil, and no soil or other materials restricted

by the regulations of the white-fringed beetle quarantine which

have not been produced under approved sanitation conditions or

which have not been given approved treatment may subsequently be

placed in such protected areas,

RAISED PLUNGING BED

A bed or bench elevated to a height of at least 12 inohes above the ground
preferably 18 inches Proteoted during the season of adult beetle
activity by an approved barrier (Plate 2)

Corners or other places where the sheet neta&'. of the barrier joins must be
welded or otherwise united in manner approved by an inspector

APPROVED METAL BARRIER


This barrier is constructed of 28 gauge galvanized sheet metal.
effoiienoy is in direct proportion.to the nsmoothness of its surface,
must be exercised to keep the surface above ground free from plants,
or debris. The sheet metal should be securely fastened to the 2 x 4
