    How are dandelions doing
    in HRM in 2014?
    Site posted April 5, 2004.

    This website offers detailed, referenced information on the biology, monitoring and control of chinch bug, and links to complementary resources on the web. The emphasis is on adoption of cultural practices which reduce the incidence of pests and diseases generally as well as demands for fertilizer and water and which are worthwhile adopting regardless of chinch bug problems. Sections on Acute Controls and Permitted Materials explain some of the issues involved in identifying alternatives to pesticides to treat existing pest infestations.

    1. Quick Links & Current Issues


    HRM's Pesticide By-Law & Sustainable Gardening & Landscape Maintenance
    About the Halifax Regional Municipality Pesticide By-law: what can and can't be used, how to report violations, overview reports etc.

    Non-Essential Pesticides Ban for Nova Scotia New regulations restricting use of many pesticides on lawns and ornamentals province-wide were passed by the Nova Scotia legislature in 2010. A list of allowable pesticides - similar to HRM's Administrative Order 23 Materials List - specifies what can be used. The sale and use of pesticides not on the list will be prohibited on lawns as of April 1, 2011. The legislation will extend to ornamental shrubs, flowers and trees on April 1, 2012. But we still need the HRM By-law!

    CHINCH NOW
    A Quick Guide to diagnosing a chinch bug problem, and how to deal with it.

    Pyrethrins and Neem Oil for Control of Chinch Bug They are allowed under most pesticide bylaws and are being used to control chinch bug in communities with pesticide by-laws. Regardless, pyrethrins pose significant heath hazards and both materials (neem and pyrethrins) are highly toxic to honeybees and to aquatic invertebrates and fish.

    Other Pests
    Dying grass could be due to other pests and diseases.
    See also Got Pests? (Maine Board of Pesticides Control) for dealing with pests in the home, trees and shrubs, fruit, vegetables as well as turf.

    The Clover Option
    Clover lawns are trendy and solve many lawn problems. Spring and late summer are the best times to overseed clover into a lawn.

    Endophytic Grasses for Turf
    Are they the answer to controlling pests? Not yet.

    Consider using a Reel (manual) mower and/or a Scythe It's easier than you think - and good for the environment! The Scythe is the oldest and most environmentally friendly grass-cutting tool.

    Defining what's legal under the Pesticide By-Law A proposal to replace Administrative Order No. 23 by direct reference to a professionally maintained 3rd party list.

    2. Purpose of the Web Site


    In recent years, many communities in Canada have encouraged reductions in use of pesticides for cosmetic purposes and some have passed legislation to eliminate their use in lawns and gardens. The town of Hudson, Quebec, adopted such legislation in 1991. HRM (Halifax Regional Municipality) was the first large municipality to do so, introducing its Pesticide By-law in 2000.

    The HRM Pesticide By-law was phased in gradually and 2003 was the first year that it applied to all residential properties. There was one major problem: in both 2003 and 2004, a large number of permits for use of diazinon and Sevin (carbaryl) for control of chinch bug were issued under a notwithstanding clause.

    Pesticides are at best only a short term solution to a chinch bug problem. The chinch bug is not a dangerous, exotic pest which must be exterminated before it spreads. Rather, it is a normal member of the insect fauna of lawns and grasslands. It is the cultural conditions of the lawn that cause outbreaks of chinch bug and damage to the lawn. In fact, chinch bug was not known as a significant lawn pest in Canada until the 1970s[C1] and its ascent coincided with the intensification of fertilizer and pesticide use on lawns.
    The major factors that make lawns susceptible to chinch bug attack are severe water stress, excess thatch and excess nitrogen. Sustainable, pesticide-free control of chinch involves managing these cultural conditions to improve grass health and resistance to chinch bug (and other pests).
    Thus, truly sustainable solutions to the chinch problem are ones that address the cultural conditions. Changing the cultural conditions to foster a more ecologically self-sustaining system will, as well, reduce the incidence of all pests and diseases and the demands for fertilizer and water.

    The prime purpose of this website, set up in April of 2004, is to outline some options for control of chinch bug (and other lawn pests) in HRM by cultural methods and provide links to complementary resources on the web. By doing so, it is hoped this site will
    1. help residents identify practices they might apply or ask lawncare companies to apply to prevent or control chinch bug (and other pests) without using pesticides;

    2. heighten the awareness of lawncare professionals of the many options and services that they can employ, other than pesticides, for control of chinch bug;

    3. encourage a move towards adoption of more ecologically based cultural practices as a way of reducing all pest problems in lawns and the demands for fertilizer and water;

    4. bolster the support of the Pesticide By-law by municipal council and residents of HRM;

    5. help to make a case for changing building codes to require a higher quality of lawn construction in new developments.
    The intent of the HRM Pesticide By-Law is to eliminate cosmetic uses of pesticides in the yard and garden and on public properties. In practice that is achieved by encouraging cultural controls of pests such as those we are advocating for control of chinch bug and, when pesticidal materials may need to be used (e.g. during the transition to more effective cultural controls), restricting those to a set of 'permitted materials' (also referred to as 'permissible pesticides' or 'alternative materials'). In the section on Permitted Materials on this web site, how such materials are defined is explained and related resources on the web are highlighted. It is hoped this will
    1. help individuals to make informed choices in the selection of 'alternative materials' for control of pests.
    Generally it will not be possible to answer individual queries such as where to find particular types of products or how to carry out a particular practice. Residents are encouraged to direct such questions to personnel in their local garden supply stores and landscaping companies, HRM and Clean Nova Scotia (the agency administering the Pesticide Permit process in 2009). Landscaping companies can supply most, if not all, of the services outlined in the guidelines for control of chinch bug.

    3. Layout of the Web Site

    The website has 9 sections plus the CHINCH NOW page, which provides a quick overview for someone dealing with an immediate chinch bug problem.

    V PERMITTED MATERIALS
    The material inputs that can be used for control of pests in HRM under the Pesticide By-law are defined by Administrative Order No. 23. This section explains the concept of a Permitted Materials List and cross references the List in Administrative Order No. 23 with that in the CGSB Organic Standard (and OMRI).

    VI CONTROL: OVERVIEW
    Controls for chinch bug are presented in three sections corresponding to three levels of control. The first (acute controls) consists of short term measures to stop a developing infestation. Higher levels of control are preventative in nature and address the underlying conditions that predispose a lawn to damage by chinch bug.
    Overview Page

    Page in Frames
      ACUTE CONTROLS
    These are short term measures to stop a developing chinch outbreak (e.g., by physical removal, use of pesticidal soap or beneficial nematodes); they do little for long term control
    See Page

    Page in Frames
      CULTURAL CONTROLS These involve changing lawn maintenance practices to relieve the lawn conditions that are conducive to chinch bugs without changing the fundamental nature of the lawn, e.g., watering the most drought susceptible areas, mowing higher, reduced nitrogen use.
    See Page

    Page in Frames
      REDESIGN Control by redesign involves more fundamental changes designed to make the system more self-sustaining and pest resistant and may require significant structural and/or aesthetic changes in the lawn system, e.g., introducing clover, adding shade trees, lawn renovation to increase soil depth and quality.
