What exactly is a Pesticide Truth?

Correction: TreeAzin – It Says, No More Than 1 App per Year recommended
Correction: TreeAzin Being Applied every year according to David Barkely, Manager of Forestry Services Ottawa.
July 2013- Instead of injections every two years, the city’s moved back to applying the chemicals annually, because many trees it treated have died anyway
The homeowner version or Merit 75WP appears to be available in Quebec.
Webinars on the EAB with industry experts in the U.S. indicate this is a fairly effective product against EAB when used on smaller DBH trees.
Merit as Soil Drench for GreenHouse and Nursery PCP# 25636 Merit 60WP
Merit soil drench – as per label conference at American University in February 2013 is really effective on smaller DBH trees, with testing is still ongoing on larger trees.
The other aspect which is a potential issue on both soil drench and bark spray are:
• Off target exposure – contact with pets, flowers, vegetables, birds or other insects which were not the intended target.
• Leaching of chemicals – especially into groundwater
Note when you look at American sites, you will rarely find TreeAzin listed as it has only been used / registered in the U.S. recently compared to many other products.
There is also a comparison between protecting an ash tree versus removal and replacement, with no discussion on the actual benefit of a mature tree. A lot has been learned over the past decade on tree benefits to the urban landscape, and how much a mature tree really is worth and what the impacts of loss might be.
These range far beyond the actual replacement cost of the tree itself.
You will also see bark spray mentioned in American articles, this is not available nor legal for use in Canada.
Note: the lack of Merit soil drench or bark spray is not related to the Cosmetic Pesticide Ban in place in the Province of Ontario.
The Topic of the original post was about Mark Cullen Misinformation and his Anti Pesticide money making schemes.
Speculations dangers about ground water and pets is just that. (FearMongering to create a market for TreeAzin)
Repeat FYI: Merit as Soil Drench for GreenHouse and Nursery IN ONTARIO (Available to be abused off label at your own peril. Just ask a local farmer, we are told) PCP# 25636
Some American references – note as American TreeAzin will be not mentioned, and there will be pesticides which we can not get legally in Canada.
In recent years, the EAB has demonstrated time and time again what has now become known as the Death Curve. And it is a fact on how quickly the death of trees accelerate. Ash trees not treated will die.
While this is shown to be pesticide truths – often times only part of the story is told and very little reference to any external research is provided or discussed/reviewed.
Further to this a cost from an article by Mark Cullen, and somehow highlighting it to make it sound wrong. Over the life of the treatment, perhaps eight or ten years, Mark stated a price of $800-1200. That works out to perhaps $100 per year, is that not unreasonable to have a professional protect your largest landscape investment? We often times pay more than that on ineffective weed control! Yes the product is expensive, too much so in my opinion, but so is Confidor and any other chemical or medication we buy. Of course the manufacturers are paying for their R&D and Canadian pesticide registration costs (which can be high).
How effective is the treatment for EAB (TreeAzin)? Unlike Dutch elm disease, which killed virtually all of the American elm trees that lined our streets in the 1960s and early ’70s, the EAB can be controlled using TreeAzin, a “biologically based” liquid that is injected into the tree by licensed professionals. TreeAzin is a derivative of the neem tree, a native of southeast Asia.
