I noticed something that initially appeared to be white fungus on my apple tree. However, upon closer inspection, I discovered the white fungus was actually woolly aphids!
Woolly aphids are aphids that feed on the sap of a plant and secrete a substance that resembles white cotton or wool. Symptoms of feeding may include twisted and curled leaves, yellowed foliage, poor plant growth, low plant vigor, and branch dieback.
I pruned back what I could to slow down the aphid growth, and I will try out a recipe for homemade insecticidal soap on the remaining aphids. If it ends up being effective, I will share the recipe in a later post.
Note: To determine whether you have woolly aphids on your tree, all you have to do is rub the white substance. If a purple stain appears, then you have a woolly aphid problem on your hands; not fungus.
