Current through Register Vol. 50, No. 12, December 20, 2024

A. The purchaser in Louisiana of out-of-state nursery stock will be held responsible for proof of origin of citrus trees in his possession. Purchase receipts will be considered adequate proof of origin, but citrus invoice reports will not be considered adequate proof.

B. Citrus nursery stock, scions and/or budwood may move into Louisiana from areas where tristeza is not known to occur, provided the certifying official in the state of origin states on the certificate of inspection that the nursery is located in an area of the state of origin in which tristeza is not known to occur.

C. Citrus nursery stock, scions and/or budwood may move into Louisiana from areas in which tristeza is known to occur, provided it has been grown under a citrus budwood registration program against tristeza, xyloporosis, psorosis and exocortis, and provided that under this registration program the following are required.

1. The nursery stock, scions and/or budwood is from parent stock that has been tested on trifoliata rootstock at least three years and shows no indication of exocortis.

2. The nursery stock, scions and/or budwood is from parent stock which has been indexed and found free of tristeza within 12 months before shipment.

3. The nursery stock, scions and/or budwood is from parent stock that has been indexed and found free of psorosis and the cachexia virulent strain of xyloporosis.

4. The grower has filed a copy of his nursery certificate of inspection with the state entomologist.

5. Each shipment is accompanied by a Louisiana citrus permit tag and a budwood registration tag issued by the appropriate certifying official in the state of origin.

6. Each shipment is accompanied by a citrus invoice report issued by the certifying official of the state of origin, showing the name of the grower; name of consignee; number of trees, scions and/or buds; registered number of parent trees; variety of bud and kind of rootstock. If shipment includes budwood, it must be accompanied by a bud cutting report. A copy of the invoice and bud cutting report, when required, must be mailed to the state entomologist prior to shipment.
