I have quite an infestation. I am trying to find a way to get them under control. I have used rose dust but it has done little to stop them. I was wondering if their is an organic method.
Please give me advice.
Here is an older article: Organic Treatment for Rose Midge?.
Also, do a search over on the Antique Roses forum, there is an older article over there that discusses mostly non-organic treatments, but a couple of responses mention using a barrier method (plastic on top of the soil around the rose bush) to prevent midge from getting from the soil to the tops of the plants.
