Anthracnose on Kentucky bluegrass in July
A number of pests (e.g. June bug grubs, sod webworm, leatherjackets) and diseases (e.g. red thread) cause damage that may be at least superficially similar to that caused by chinch bug. Generally they can be distinguished by the time of occurrence, whether they affect rooting and or leaves, aerial patterns of damage, where in the lawn they appear. Most respond to the same cultural conditions that reduce incidence of chinch, notably infrequent but deep watering, higher mowing, and modest use of nitrogen.

A set of factsheets on common lawn and garden pests in Nova Scotia is poisted on the Nova Scotia Environment and Labour website; they include:
The factsheets provide guidelines on how to diagnose the different insect pests (e.g. by when they occur, nature of the damage, observations of grubs etc.) and fairly comprehensive considerations of non-chemical control options.

- Turfgrass Management Report (http://www.omafra.gov.on.ca/english/crops/updates/turfgrass/index.html) Ontario Ministry of Agriculture and Food, Spons. (Viewed 13 May 2007).
The Turfgrass Management Report provides regular reports on common lawn pest and disease problems in Ontario through the year. It's is a good guide to some of the things to look out for in N.S., remembering that we may have some pests that are problematical here when they are not in Ontario, and vice versa.
(An example is Japanese beetle, which is not entrenched in N.S., but is in parts of Ontario; however it has recently been found be in HRM so we should be on the lookout for it see Japanese Beetle including the 2005 Report).
