E. All lots or shipments in violation of this regulation shall be disposed of with the following exceptions:

1. Inspecting officers may release small lots or shipments of articles and commodities covered which may be adequately inspected provided no living stage of European corn borer is found; or such small lots may be treated in a manner approved by the Secretary under official supervision and thereafter released. (See APPENDIX I)

2. Certified Shipments of Shelled Corn Not in Conformity May be Treated or Processed in California.

a. Shipments of shelled corn entering California under certificate from states in the European corn borer infested area, which are found to be contaminated with plant portions or fragments capable of or actually harboring larvae of European corn borer, may be treated or processed in California to destroy such larvae if the state which issued the certificate has entered into a program to strengthen its origin inspection and certification for European corn borer. If a state wishes to enter this program, a signed agreement from the origin state agricultural regulatory agency must be received and accepted by the director. The agreement shall affirm that the origin state agricultural regulatory agency agrees to:

1. Use specified type of uniform screening and/or treatment certificates.

2. Certify as to all the following conditions:

aa. Inspection of each car or truck before loading;

bb. Constant checking of screens and loading procedures (includes replacement of damaged or broken screens as necessary);

cc. Moving corn through screening and loading process at an established rate which assures only clean corn going into the railroad car or truck; and

3. Each lot of shelled corn grown in or shipped from the infested area shall be accompanied by a certificate issued by an authorized representative of the origin state Department of Agriculture stating:

aa. The grain has passed through a l/2 inch or smaller size mesh screen, or

bb. The grain has been treated for European corn borer in a manner approved by the Secretary.

4. Screening, processing, or treating shall be done under state supervision.

5. California agricultural regulatory officials will monitor shelled corn shipped from infested states to determine program conformity. If within a one-year period more than three violations from one location are found, the agricultural regulatory officials of the origin state will be informed and they will terminate issuance of the specified program certificates for shelled corn from that location. The origin state will be required to tighten its certification program before resumption of shelled corn certification shipments from that location.

b. Before any shelled corn is treated or processed in California under (E.2.a), permission must be obtained from the Secretary (through the Pest Exclusion Branch). The location where treatment or processing will take place will be specified when permission is given.

APPENDIX C 02-10-15

1. Shelled Grain may be certified under (D.1.b) provided it had passed through a ˝ inch or less mesh screen prior to loading and is believed to be free of stalks, cobs, stems, or portions of plants or fragments capable of harboring larvae of ECB, and, further, that the car or truck has been found to be free of any such host plant fragments at the time of loading.

2. Plants or cut flowers of aster, chrysanthemum, dahlia, geraniums, gladiolus, and hollyhocks may be certified provided they meet the requirements of QC Permit No. 1409:

a. Plants or cut flowers shall be produced in an approved greenhouse(s) that are tightly enclosed to exclude European corn borer (ECB).


b. The greenhouses shall have received all host stock plant material from either an origin free of, or properly certified for ECB.


c. A minimum of two ECB traps shall be placed in each greenhouse, away from the doors, and maintained by the origin department of agriculture (DA).  The trapping period shall be May 1 through October 31 of each year. The traps shall be phermone baited ECB traps and shall be serviced weekly. Traps shall be in place from initial planting through the entire production cycle.


d. If ECB is trapped, the DA shall immediately notify the Pest Exclusion Interior Program and shall discontinue shipments of permitted plants from the greenhouse in which the ECB was trapped.


e. All plants shall be produced in sterilized potting media and in new or sterilized containers.

f. Each shipment of plants shall be accompanied by a certificate issued by a representative of DA confirming that the shipment is free from European corn borer and including the statement "Meets California’s Systems Approach for European Corn Borer."  The certificate shall also provide the name and address of the shipper and consignee as well as the number of plants in the shipment.


g. In lieu of a paper certificate, a sticker or stamp‑type certificate may be used with the following format:

(State of Origin) Plants Shipped Under Authority of

California’s Systems Approach for European Corn Borer. 

Approved by (State) Department of Agriculture.



Authorized Representative


h. All shipments shall be moved directly from the origin greenhouse to the California destination without diversion.


i. All shipments are subject to inspection upon arrival in California.


j. The detection of ECB, or other serious plant pest, or violation of any of the conditions of this permit, may be sufficient cause for immediate revocation of this permit.


APPENDIX D 11-22-93

1. Certified Shipments of Feed Corn.

a. Shipments moving to ECB approved mills need not be inspected.

b. Release if properly certified fumigated at origin. All shipments are still subject to inspection for other reasons as required (weed seed, cottonseed, soil, etc.).

c. Reject, if on inspection of a shipment, corn cobs or large pieces of stalk are found that would indicate improper screening. Also, reject only if five or more small pieces of debris over 3/4 inch in diameter are found. Most corn is screened over ˝-inch square screens. A 3/4 inch piece of debris several inches long could "squeeze" through this ˝-inch square opening even if the corn was properly screened. "Pencil" size pieces of debris should be split open and the load rejected only if a live ECB is found. Research studies conducted in Kansas indicates that the ECB larvae can survive for only a limited time in stored grain.

d. Reject any shipment of corn if a live larvae of the ECB is found during inspection of the corn or anywhere on the car.

2. States with Strengthened Origin Inspection Programs

a. The following states in the infested area have signed agreements and entered into a program to strengthen origin inspection and certification. When approved by California, contaminated shipments may be treated in California from these states:

Colorado, Kansas, Missouri, Nebraska, Iowa and Minnesota

b. Inspect a random number of carriers from each shipper location when shipping state has signed agreement.

c. If excessive violations are found from one shipper location the regulatory official of the origin state will be notified and they will terminate the signing of such certificates from that location. Shipments en route prior to the notification date may be treated in California if in violation. Shipments made after the notification date should be rejected and shipped out of state.

d. Shipper locations in violation may re-enter the origin certification program when origin state officials notify California officials that corrective action has been taken to assure only clean grain will be shipped from that location.

e. Recommended Random Sample from States under Agreement

1. 20% from each shipper location (1 out of 5) when there have been no rejections for debris during the past year.

2. 40% from each shipper location (2 out of 5) when there was a rejection for debris over six months ago but less than one year ago.

3. 60% from each shipper location (3 out of 5) when there was a rejection for debris over three months ago but less than six months ago.

4. 80% from each shipper location (4 out of 5) when there was a rejection for debris over one month ago but less than three months ago.

5. 100% from each shipper location with a rejection for debris within the past one month.

f. Excessive Violations from One Location

1. Three within any one-month period.

2. Four within any consecutive two-month period.

3. States Without Signed Agreement to Strengthen Origin Inspection Programs:

Inspect all shipments from states which have not entered into a program to strengthen origin inspection and certification. When excessive debris is found in shipment from these states, reject and ship out of state.

4. Terminal Facilities

If screening procedures are used at destination, inspect at regular intervals any available debris screened out of the commodity. Also inspect the unloading and storage facilities at regular intervals.

5. Recommended Intervals of Inspection of Terminal Facilities

a. Inspect daily if shipments are being unloaded daily.

b. Inspect bi-weekly if two or four shipments are being unloaded weekly.

c. Inspect other facilities on a weekly basis or after shipment is unloaded.

Require all debris originating from an infested state and found at unloading and storage facilities to be cleaned up and disposed of immediately upon discovery.


APPENDIX E 11-22-93

1. Destination treatment is permitted for feed corn that is found to be in violation due to excessive debris.

2. Because there have been so few rejections in the past year, this appendix gives all counties, with treatment facilities available, permission to treat at destination any shipment found to be in violation, provided the shipment originated in a state that is under agreement (Appendix D of the quarantine).

3. County personnel must report to the Pest Exclusion area office each shipment that is treated.

4. Pest Exclusion will contact the shipping state officials and request corrective action be taken if excessive treatments are noted from any one shipper.


APPENDIX F 09-16-02

New Mexico

The counties of Chaves, Curry, Quay, Roosevelt, San Juan, Sante Fe, Torrance, Union, and Valencia.


The counties of Bailey, Castro, Floyd, Hale, Lamb, Parmer and Swisher.

Commercial shipments of regulated items from the above must be certified. New Mexico and Texas have agreed to certify potentially infested materials to facilitate their movement across state lines.

All noncommercial shipments of articles and commodities covered by this quarantine should be rejected under the authority of Section 6461.5, Food and Agricultural Code, when originating from one of the above infested counties.


All provinces of Canada except British Columbia are infested with ECB. Shipments of regulated articles/commodities from all provinces except British Columbia must meet the requirements of this quarantine. Regulated articles/ commodities not meeting the requirements of this quarantine should be rejected under Section 6461 of the Food and Agricultural Code.


APPENDIX G            08-26-09

1. Permit No. QC 712 has been issued to the Colorado Department of Agriculture to authorize firms to ship unfumigated fresh sweet corn to California which was grown in western Colorado. Each shipment of fresh sweet corn will be accompanied by a certificate issued by the Colorado Department of Agriculture, naming the shipper; stating the identification number of the lot, the size of the shipment, and the name and address of the consignee; and affirming that the shipment is in compliance with the requirements of Permit No. QC 712. Sweet corn shipped to California under this permit is subject to inspection upon arrival.


APPENDIX H            08-21-06

Regulated Articles further defined:

1. Chrysanthemum

Under regulated articles and commodities the common name "chrysanthemum" refers to both genera Chrysanthemum and Dendranthema.

Exemptions further defined:

2. Geranium

Under regulated articles and commodities the common name "geranium" refers to plants of the genus Pelargonium which have fleshy stems and are a host to European Corn Borer. Plants of the genus Geranium commonly known as "cranesbill," "true geranium" or "perennial geranium" are not regulated articles under this quarantine. Plants of the genus Geranium are readily distinguished from Pelargonium by their "wire-thin" stem caliper.

3. Seedling Plants

Seedling geraniums (Pelargonium) and dalhias may be exempted from the European Corn Borer Quarantine as are other flowers listed in Section (D.2.c). Plants produced from cuttings are not considered seedlings and are not exempt.

4. Very Pungent Chili Peppers Exempt

a. Capsicum annuum

    1. Ornamental Groups

        aa. Cerasiforme (cherry pepper) very pungent

        bb. Fasciculatum (red pepper) very pungent

    2. Non-Ornamental Groups

        aa. Longum (capsicum, cayenne, chili, long red, and should include:  Big Jim, hot banana, jalapeno, serrano, Anaheim, and hot cherry) very pungent.

5. Bleached Cornhusks

The sulphuring process used in bleaching corn husks intended for use in wrapping tamales, etc., will eliminate all danger of such shucks carrying live European corn borer larvae. These shucks are admissible without certification.


APPENDIX I                        09-17-12

Small shipments of sweet peppers and beans in the pod, may be released if the surface of all pieces of fruit is inspected and found free from insect damage including entry holes. Any fruit demonstrating insect damage should be rejected. Small shipments of corn should not be released unless it is practical to split all cobs to determine the insect is not present.
