Roundup is a systemic broad spectrum herbicide .. when sprayed on grasses or
broadleaved plants it is taken into the plant in a matter of hours and
translocated throughout the plant. The plants start to show symptoms in 2-10
days- sooner on herbacious plants , longer on woody species. It kills the
plant by interupting amino acid sunthesis and hence protein formation.. It
is tied up on the soil almost immediately and begins to be broken down by
microbial action. That is why it is so widely used in sensitive biologiocal
situations because it does not leave any soil residue or create no off site
movement problems.
I hope this is a little more straight forward than my last post.
