I know this don't have much to do with tomatos, but feel as though it will be of interest to some of you folks. Apparently there is a lot of different ideas as to how and why kudzu was brought into the US. I had originally stated that it was due to forage for livestock, but I've found other sources that range from ornamental uses to erosional control. I've even found different dates of importation. http://www.cnn.com/US/9904/05/BC-SHEEP.reut/ http://www.hort.vt.edu/VNPS/invasive/invpuer.htm http://www.wnok.com/kudzuhistory.html http://www.mindspring.com/~wxrnot/kudzu.html http://research.unc.edu/endeavors/end496/kudzu.htm (Kudzu as related to alcohol disorders) http://www.mindspring.com/~mdpas/kudzu.html ( I felt this site was a bit comical) http://www.aphis.usda.gov/ppq/bats/fnwsbycat-e.html (current list of knoxious weeds with kudzu listed at very bottom of list) http://frwebgate.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=813746592+8+0+0&WAISaction=retrieve (7 CFR PART 361--IMPORTATION OF SEED AND SCREENINGS UNDER THE FEDERAL SEED ACT) For those of you that are interested in importation of plants and their bi-products, you would need to visit http://www.aphis.usda.gov This is the site for Animal and Plant Health Inspection Service. The fed agency that governs importation of Ag products. These are the results of a quick and dirty search. Wasn't able to locate info on regulations that delt specifically with kudzu. Maybe the Gov't don't regulate what's currently "IN" the US anymore. Of course, my knowledge of knoxious and prohibitive weeds is over a decade old now and APHIS didn't even list prohibitive weeds on their web site. Hope this helps.
