·It is currently the only effective product to use against Elm Bark Beetles that cause Dutch Elm Disease.
·There are no viable, effective alternatives at this time.
·Once a tree is treated and the product dries it is effective for two years against elm bark beetles.
Q: How it applied?
· It is sprayed on the ground within 22 cm of the tree trunks.
·Spray directly on the bottom 50 cm of the trunks of the tree.
·There is little to no spray drift.
·It is only being used by the Insect Control Branch as a direct spray on the base of elms trees where appropriate. (most jurisdictions in the US and any provinces that have a Dutch Elm disease program can use Dursban if they had access to product and licensed pesticide applicators)
Q: Is Dursban banned?
·It is for some uses but not for all uses, registered usage is still permitted in US as well as other provinces until the end of 2014; it cannot be used within structures but can be used to treat a variety of insect pests outside of homes.
·Dursban is only banned for application/use within houses, schools, apartments, etc (structures) for structural pest control.
Q: When is it safe to be near or on the sprayed area?
·It is safe to be near the treated area at any time once product has dried. The only time there is any perceived risk is when its wet on the bottom 50cm’s of t he bark but the smell of the Dursban would normally keep all away from touching or eating the bark.
·Notices would be present in public areas at the time of application to advise people of the products presence.
Q: How do I know what areas are to be sprayed?
·A map is provided that includes where the City intends on spraying Dursban and is attached at
·Where it is being sprayed on private property (river properties) the residents receive notification.
·Signage is placed on all boulevards, park entrances and anywhere possible where treatment has occurred. Signs remain up for most of the day and removed at the end of the shift. Signs have dated sprayed, product used and 311’s # on it for further information.
Q: Is City Council approval required?
·Permission is granted for its registered use as a part of a Dutch Elm Disease management program and its proper urban use is identified on the label
·Permission for use is from the Pesticide Use Permit issued to the Insect Control Branch by the Province of Manitoba, Conservation.
·After 2014, the label/product is not being renewed and an alternative is not in sight at this time for the effective control of elm bark beetles.
