Thanks for the additional info on kudzu Byron. Yea, I wish they would come up with something to use this plant for, extensively that is. Might as well eh?? Seems fitting to me. It's here, let's use it. Also, Roundup is a contact poison. I've heard of and witnessed evidence of cases where the spray, or some sort of mist that is wind blown, killed trees 50 yards from where the actual application was located. You do not want to apply this stuff on a windy day. Might get ya into legal trouble with a hostile neighbor. My preferred method of applying chemicals such as round up is using a wick system. Use of a wick system can be accomplished in any kind of environmental conditions, except in gully washers. All ya need is some pvc pipe (sch 40 preferrably) and some cotton rope. There are various designs for this sort of system and can be made much cheaper than buying it pre-made. Your local or county Ag extension agent and/or specialist should have pamplets on making and using a wick system. These systems are easy to store. I have known folks to use roundup as a "pour on" along fence rows. Works really well when controlling those dreaded weeds along the fences, but, there is some detrimental affects to the soils when chemicals such as this are abused in manners similar to this. Hope this info helps. Paul Reynolds Environmental Agronomist Austin Texas
