Checklist before sending Phaseolus vulgaris seeds

Please review this check list before you sent Phaseolus vulgaris seeds and make sure that:

Phytosanitary certificate is included, stating that the dry bean seed has been fumigated and treated with fungicides (see here) and comes from an area that has been officially inspected during the active growth of the crop, and found to be free of Pseudomonas syringae pv. phaseolicola and Curtobacterium flaccumfaciens pv. flaccumfaciens.

Use a courier to send the seed if possible. Fed ex does a good job in Chile, however other companies have not worked well for us.

An invoice listing the quantity of material shipped and value per kilogram (value of soybean US$0.25 per kilo) must be included. It should state "no charge to consignee” and add a statement that the “Invoice value is for customs purposes only. This seed is not for resale. It is for research and development and re-export only”.

Include original airwaybill, invoice, and phytosanitary certificate. Get two originals of the phytosanitary certificate if possible, save one just in case there is a problem.

Planting plans and or instructions are inside the box or have been e-mailed to MAS.

Make sure MAS has been sent a fax/email with a copy of the documents listed in number 4 above.

Make sure harvest/row tags have been included if needed or send them later.
