(a) This subpart shall only apply to covered tropical crops in the tropical region for the 2006 and subsequent crops years, as those terms are defined in this subpart. Benefits under this part may be extended to those crops only to the extent that they are other-wise eligible for assistance under this part. Covered crops shall not apply to "value loss" crops,as defined else-where in this part. For those crops that are covered by this subpart, loss and payment determinations for the pro-gram covered in this part shall be de-termined by the rules that otherwise apply to the program subject to the modifications provided by this subpart. The rules that otherwise apply include, but are not limited to, limitations on payments that appear elsewhere in this part.
