Horse Chestnut Leaf Problems...

Recommended Posts

I wondered if the following was useful to anyone..? The following picture shows a Horse Chestnut leaf with both the Leaf Miner (Cameraria ohridella) at top left and Leaf Blotch (Guignardia aesculi) at lower right.

 

Notice how the leaf blotch has the yellowing between the fungal attack and the main leaf colour, yet the leaf minor does not show this. In fact, you can see the frasse left by the leaf miner in the blister at top left.
