least-toxic controls policy

[EWerb at aol.com]

i got this message from someone working with local schools to cut back on 
poison use around schools, certainly a good place to start...what group-mind 
thoughts might we offer?...

Anyone have suggestions for weed abatement around schools?  Weeds seem to be 
the worst "pest" to solve.......and Roundup is the easiest thing to use.  
Our 2 reps to the committee implementing the least-toxic pest control policy 
at Ventura Unified are being ganged up on to put a herbicide on the 
"acceptable use list". We don't want to, but have to counter with a potential 
solution that's effective & cheap. Phil Boise (from SB) is the consultant on 
this and has done a good job problem solving other pests but could he be 
overlooking something? Something experimental that shows promise?
Some mechanical means have been ruled out. (ie. Flamers have too much 
liabilty for use).  The BIGGEST problem is a weed problem that got out of 
hand while they were hammering out the list of acceptable controls. Too late 
for mulch?!
Ideas?
