Prior to 2002, we had no history with emerald ash borer (EAB) the way we do with native pests. We also had no established methods to control it. Instead, we have had to develop logical treatment strategies based on the best information we have at any one point in time and adapt our strategies to new information as it becomes available.
Since 2008, TreeAzin® Systemic Insecticide has been used to treat thousands of trees across Ontario and Quebec for EAB. After five years, we are beginning to see trends emerge. We have been fortunate to be able to work with the Town of Oakville to monitor treatment efficacy. Each year we have evaluated our biennial treatment strategy on some 350 treated and untreated trees in Oakville. This year we are expanding the survey to some 850 trees.
Here is a brief summary of what we are seeing:
- Initiating treatment in the early stages of an EAB outbreak is critical to successful treatment. In Oakville, 98% of the 5,300 trees treated since 2008, are still alive. Trees that were first treated in 2008, 2009 and 2010 are, in general, in good condition in 2013. Trees that were first treated in 2011 or 2012 are more variable in condition: some appear to be doing well but others are not. TreeAzin is injected into the base of a tree and moves throughout the tree via its conductive tissues. EAB feeding destroys these tissues and, eventually, the damage is so significant that movement of TreeAzin is impeded and the treatment becomes less and less effective. It is similar to a vaccination administered into a human at the ankle. The vaccination will spread throughout the body via the body’s veins and arteries. However, if the veins have been partially or completely severed at the thigh, the vaccination cannot circulate around the body. EAB essentially severs the tree’s “veins and arteries,” preventing TreeAzin from circulating within the tree. This is why timing of treatment is so crucial to the health of the tree.
- Green ash appears to be much more vulnerable to EAB than white ash, so it is essential to initiate treatments on green ash as soon as EAB has been detected within 25 kms of your area. White ash should be treated soon after to minimize damage.
- If you have not treated your ash yet, and you are in the Ottawa or Toronto areas and want to try to save your tree/trees, we suggest the following steps:
- Have your tree assessed by a certified arborist. The arborist should assess your tree for evidence of EAB attack but, just as importantly, they should assess general ash tree condition in your neighborhood to get some sense of the EAB situation. If EAB is causing damage on neighboring ash, then you must assume that your tree is affected too, even if it looks healthy. One thing we have learned is that when it comes to EAB, the situation is always worse than it appears! Always!
- 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.

Why is an Ottawa newspaper acting as a SALES REPRESENTATIVE for TreeAzin ?!?! Why is this newspaper providing residents with FALSE HOPE about TreeAzin ?!?! IF TREEAZIN IS THE ONLY OPTION, IT WOULD BE BETTER TO DO NOTHING RATHER THAN USE TREEAZIN ― MUNICIPAL EMPLOYEES SHOULD SIMPLY BE EQUIPPED WITH CHAIN SAWS. Ottawa residents should get used to the sound of chain saws ! City of Ottawa will spend EXORBITANT AMOUNTS OF MONEY because the Province of Ontario ARBITRARILY IMPOSED PROHIBITION against pest control products that could have been used in the early stages of the EMERALD ASH BORER INVASION. Can MUNICIPALITIES like Ottawa afford the HARDSHIP AND COST of this #@!!% PROHIBITION NONSENSE ?!?! When it comes to Anti-Pesticide PROHIBITION, Municipal Officials can learn a lot from the experience of those jurisdictions that have SUFFERED THE HARDSHIP AND COST AN FAILURE OF THIS #@!!% NONSENSE ! http://wp.me/P1jq40-445 http://wp.me/P1jq40-3yl And there is little debate about the fact that ARBITRARY PROHIBITIONS convert communities into SHABBIER AND DANGEROUS PEST-INFESTED GARBAGE DUMPS. http://wp.me/P1jq40-44g http://wp.me/P1jq40-4z3 PESTICIDE-FREE means DEAD TREES and WEED-INFESTED PLAYING SURFACES. EMERALD ASH BORER, a wood-boring insect that is HIGHLY DESTRUCTIVE to Ash Trees, is an example where Anti-Pesticide PROHIBITION led to municipalities being forced to spend STUNNINGLY EXORBITANT AMOUNTS OF MONEY AND RESOURCES. For several years, TreeAzin was the ONLY COMMERCIAL TREATMENT available in jurisdictions where Anti-Pesticide PROHIBITION has been ARBITRARILY IMPOSED. TreeAzin is a so-called Green Alternative Pesticide that supposedly replaces conventional pest control products. Other municipalities, like Ottawa, have admitted that TREEAZIN IS A DISMAL FAILURE, and are bringing in Confidor, at one time a PROHIBITED PRODUCT. Ottawa has admitted that if TreeAzin is THE ONLY OPTION, it would be better to DO NOTHING rather than use TreeAzin. TreeAzin ( aka Neem Oil ) DOES NOT WORK ! http://wp.me/P1jq40-2G4 It is IMPOSSIBLE TO CONTROL EMERALD ASH BORER without conventional pest control products. TreeAzin provides MARGINAL CONTROL AT BEST. In jurisdictions, like Ottawa, where Anti-Pesticide PROHIBITION has been IMPOSED, Municipal Employees should simply be equipped with CHAIN SAWS. If municipalities truly want to save their Urban Forests, then they should have their LOCAL PROHIBITION RESCINDED. http://wp.me/p1jq40-5NR Across North America, Municipal Officials are THINKING TWICE ABOUT PROHIBITION by looking at the experience of those jurisdictions that have suffered the HARDSHIP AND STUNNINGLY EXORBITANT COSTS OF THIS #@!!% NONSENSE ! http://wp.me/p1jq40-5×1 http://wp.me/P1jq40-43V In fact, THERE ARE REAL TRENDS AGAINST PROHIBITION. The following jurisdictions STOPPED or RESCINDED or LIMITED or OPPOSED Anti-Pesticide PROHIBITION, or granted professional lawn care businesses with an EXCEPTION STATUS … Alberta ( Province ), Altona ( Manitoba ), Ashland ( Oregon ), Beaumont ( Alberta ), British Columbia ( Province ), Calgary ( Alberta ), Campbell River ( British Columbia ), Chicago ( Illinois ), Durango ( Colorado ), Edmonton ( Alberta ), Everett ( Washington ), Guelph ( Ontario ), Guelph-Eramosa ( Ontario ), Kamloops ( British Columbia ), Kelowna ( British Columbia ), Merritt ( British Columbia ), New Brunswick ( Province ), Newfoundland & Labrador ( Province ), Ogunquit ( Maine ), Port Alberni ( British Columbia ), Portage La Prairie ( Manitoba ), Quebec ( Prohibition Invalidated When Lawsuit Defeated Ban ), Regina ( Saskatchewan ), Rossland ( British Columbia ), Salmon Arm ( British Columbia ), Scarborough ( Maine ), Saint John’s ( Newfoundland & Labrador ), Steinbach ( Manitoba ), Stuartburn ( Manitoba), Vernon ( British Columbia ), Winkler ( Manitoba ). http://wp.me/P1jq40-1JO THE TRENDS AGAINST PROHIBITION CONTINUE. NO ONE CAN AFFORD THIS #@!!% NONSENSE OF ALLOWING HUNDREDS OF THOUSANDS OF TREES TO DIE ! WILLIAM H. GATHERCOLE AND NORAH G https://pesticidetruths.com/ http://wp.me/P1jq40-2rr
