Basil downy mildew - Recently basil downy mildew was identified on basil plants in a greenhouse in Maine. This destructive disease, first found in the northeast in 2008, produces an abundance of spores and can spread quickly. Growers should look for yellowing on basil plants that may look like a nutritional problem. Upon closer examination plants infected with downy mildew will have purplish gray spores visible on the underside of leaves.

Adelgid crawlers are still abundant, so if you are living/recreating or working in or near HWA infested areas please bear in mind the risk of spreading the insect this time of year. Check your hemlocks for signs of this pest, especially those within 20 miles of the coast. If you do find HWA, please let us know. To date HWA infestations have been confirmed in the following towns: Brunswick, Harpswell, South Portland, Bristol, South Bristol, Westport Island, Arrowsic, Georgetown, Phippsburgh, Eliot, Kennebunkport, Kittery, Ogunquit, Saco, South Berwick, Wells and York. More information about the life cycle of HWA can be found at: http://www.maine.gov/doc/mfs/HWALifeStages.htm. Asian longhorned beetle - A small infestation of Asian longhorned beetle (ALB) was confirmed in six red maple trees in Boston, MA over the Fourth of July weekend. The trees located across the street from the Arnold Arboretum, a showplace for trees and their beauty, have since been removed and chipped. If ALB is in Maine, we would expect adults to have begun emerging by this date. If you think you have found ALB, please try to capture and/or photograph the beetle and then contact our office or use the Maine Department of Agriculture on-line report form (www.albmaine.org, right hand column). The Maine Department of Agriculture will be conducting a survey for ALB at Sebago Lake State Park on Saturday August 14.
