Re: Re: CULT: Preemergent vs. Postemergent herbicides and health

Linda, thanks for pointing me to toxicology, and Jean, thanks for the many
study sites, and everyone else for their comments.

I was particularly interested in Trifluralin today.. I'm heading out to use it
today.  SpecLab has a site they're expanding with lots of toxicology
information on a wide number of products.   Regarding the preemergent
Trifluralin (Preen, MiracleGro, others), on their site I find

"If released to soil, trifluralin is expected to biodegrade and volatilize to
the atmosphere. The persistence of trifluralin in soil has been estimated at
approximately 6 months.. Trifluralin is expected to biodegrade under both
aerobic and anaerobic conditions in soil. It is also expected to rapidly
volatilize from both moist and dry soils to the atmosphere. Trifluralin will
strongly adsorb to soil.  If released to water, trifluralin is expected to
biodegrade under both aerobic and anaerobic conditions and undergo direct
photolytic degradation."
