A project to combat the red lily leaf beetle has taken on the Cornell Cooperative Extension office in Erie County as one of its partners.

You can read more in an article on the red leaf lily beetle by the Master Gardeners of Erie County in this month’s issue of WNY Gardening Matters.

The University of Rhode Island has been researching the biocontrol of the beetle by introducing wasps from their native lands, natural enemies of the beetles.

A two-year biocontrol project was started by a team at Cornell University and is partnering with Cooperative Extension office in Putnam, Suffolk and Schoharie counties as well as Erie County.

You can also see more information about the larger project in this earlier article in Buffalo-NiagaraGardening.com.

  1. In the past several years we have had terrific luck with million bells. Last year and this year we have lost a few of these annuals. There is white fungus or parasites on the plants that cause them to die. I can only describe it as the size of maybe dandruff or tiny pieces of white lint. Can anyone tell me what this is? We tried putting systemic granules in the soil but lost 2 of our plants. Maybe applied it too late?
