Reference Material- one of the better internet references for Pesticide Labels and MSDS sheets is http://www.cdms.net/manuf/manuf.asp

It will take a while to accomplish what has been asked for in the area of weed identification and control. A good reference will be http://twig.tamu.edu being developed by the Texas Weed Information Group. I think it is a site worth bookmarking now.

I had a question on controlling weeds in tanks and ponds and there is a good internet site for that information it is http://aquaplant.tamu.edu/, refer to "Management Options".
