Organic Lacebug control.
Lacebugs are a BIG problem at our wildflower seed farm and we are looking for an organic method to control them. Being a farm another challenge for us is the scale of this effort, which could be acre(s). Do you have any advice or can you provide contact information for someone that could assist? Thank you very much for your time.

We received the following information from an MSU faculty member but you may want to talk with them directly. If you need more information please reply.
I would like to know which wildflower species are heavily infested with lace bugs. Is there any damage? What are the wildflowers being used for?
So, natural control is best. Check with the grower to see if any pesticides have been used in the last year. A synthetic pyrethroid may suppress predators for 3 – 6 months. I am not sure how well insecticidal soap or a 2% oil spray will work, or what toll it will take on flowers. They are both less damaging to leaves, but risky on flowers. BotaniGard is also a possibility. One last thought is Endeavor, since it is an IGR.
Hi and thank you for your response. We are growing the wildflowers for their seeds. We are the grower. If interested in our farm check out www.michiganwildflowerfarm.com. The Lacebug infestation impacts our production plots of:
The damage from lacebug takes place prior to flower and has killed plants or weakened them to the point of not flowering. We have used insecticide in the past and want to try organic options. We are working to keep the field clean to prevent overwintering insects and have moved crop locations. Lacebugs are known to prefer hot and dry conditions and we are amazed that we are already seeing adult lacebug despite our very wet and cold season just ending now. I have reached out to other resources and am going to try Molt-X, a botanically based insecticide/nematicide, active ingredient Azadirachtin.
