ABSTRACT:
The present invention relates to the use of paraquat as a root control agent. It is based, at least in part, on the results of green house testing in which application of paraquat ion as a dense foam to tree roots resulted in the destruction of the test roots without causing damage to the upper portion of the trees. The inactivation of paraquat by organic materials, under these circumstances, becomes an advantage, as it prevents toxic levels of paraquat from traveling downstream from the point of application
