White webbing on Red Currant bush
Some white webs showed up on a Red Currant bush last week. Now there is a powdery substance on the leaves. I looked up some information on the extension website. At first I thought it was spider mites that was causing the problem from what I read but it stated that the spider mites usually occurred during real dry conditions. That is not the type of weather we have been having so I was thinking it had to be some other type of insect. Do you have any suggestions about what is causing the problems and how do I treat the problem?

Photos would have been helpful. It sounds like spider mites. The weather does not necessarily have to be hot and dry. The powdery substance could be powdery mildew. https://extension.umn.edu/yard-and-garden-insects/spider-mites https://extension.umn.edu/plant-diseases/powdery-mildew-trees-and-shrubs
