What exactly is a Pesticide Truth?

Below is information submitted to us by a friend and customer. Keep in mind it is Canadian focused information.
There is a website called “Pesticide Truths” which has some good information, but some of it is somewhat biased.
Often times it will attack the Ontario Cosmetic Pesticide Ban, and sometimes for good reason. The ban was as much a political creation as a scientific one, perhaps more political than scientific in fact.
On the other hand, there is often information on the site which is too one sided, and consequently is off target when trying to present the “truth”.
A recent article on their, which spoke to a Mark Cullen publication is one example.
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.

2009 – We've been using TreeAzin for two years and we've injected 400 to 450 trees and we've seen very positive results," said David Barkely, the manager for forestry services in Ottawa, adding that the city spends between $75,000 and $100,000 yearly on TreeAzin treatment and that council has recently increased its budget.
The cost of TreeAzin can be extremely limiting, said Barkely. It can set back the city between $250 and $400 per injection.
One injection eradicates and inoculates an ash tree against infection for up to two years.
Correction: TreeAzin Is not Working and they are treating Yearly, according to David Barkely in 2013.
July 2013 – The city’s finding that the pesticide it’s injected into some ashes it considers especially important (because they’re especially large and beautiful or because a whole stand of threatened ash trees provides shade for a playground, for instance) isn’t working. Instead of injections every two years, the city’s moved back to applying the chemicals annually, because many trees it treated have died anyway. Even half a dozen ashes shading the playground of City Hall’s daycare are dead or dying, despite the telltale metal tags hammered into their trunks showing they’ve been treated.
“We don’t know if it’s condition, where the tree is growing, the population,” Barkley says.
- If you decide to treat your tree with TreeAzin, then do so immediately.
- Next year, have your tree re-assessed by an arborist and if the tree has not deteriorated significantly, we suggest that you re-treat your tree in 2014. This process should be repeated in 2015 to help insure your tree’s survival. It may be possible to switch to biennial treatments if the tree is doing well.
We will continue to evaluate our EAB treatment strategies and keep you posted.

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. Neem is popular as a plant shine and used for control of the lily beetle on oriental lilies.
