And Gordons "Avenue South" has penoxsulam as part of its active ingredients for turf. .


Bayer offers this "Bio-Advanced" southern weed control product with low toxicity and low environmental impact. Contains penoxsulam and other herbicides. The LD50 for rats is greater than 2000mg/kg. Almost non-toxic.


Furthermore, if you are an organically-oriented company--drive an electric vehicle. The logic is that if you drive an electric--the customer may allow you to spot spray a tiny bit of triclopyr--it is a psychological thing--a mental trade-off. An advantage over your conventional competitors.

I thought this was a “ORGANIC” forum?
Someone once told me "Organic lawn care is a process, not an event."
That being said, there are exceptions to every rule. There are problems that come up where organic methods or products will not solve. An organic program does allow for "rescue treatments" if approved by the property owner. In cases like this a non-organic product may be utilized to solve the problem. After that, return to the organic program.

All that being said, there are currently no regulations defining what is "organic" in the landscape industry only agriculture.

Maybe triclopyr is not really organic.
When I think about it mesotrione is safer and you only need 4 to 8 ounces per acre.

Carfentrazone is also very low toxicity and you only need o.o3 ounces per thousand sqft, 0.9 to 1.5 ounces per acre.
" Carfentrazone-ethyl, the active ingredient in QuickSilver herbicide, is one of the most environmentally sensitive herbicides available. It does not impact birds or earthworms and is unlikely to harm honeybees." this from

As a spot spray you could use a tiny 6 ounce squirt bottle.
Carfentrazone (Quicksilver) works best on young weeds--dandelions--probably not. You dig those out with a weed spade, right?

Hand pulling of weeds is a lot of work.
Remember weeds cannot sprout from roots --only from rhizomes.
In theory, goosegrass cannot resprout if a clump is cut off at ground level--same for crabgrass. Same for spurge. Most annuals cannot sprout from their roots.

Perennial weeds like wild violets, Canada thistle, clover, ground ivy, veronica and sorrel have underground rhizomes. New shoots will arise from the rhizomes. The soil temperature must be warm, of course.
