aryln it is a systemic and I have high hopes for it I bought another additive a sticker that is supposed to make it more effective,so with regular sprays in the spring hopefully I can have the foliage looking good again. The triple 20 I think is a different product with a different ingredient I have heard it used to treat bulb rot but I am not sure if it is effective for leaf spot. I had to use the spray for the leaf hoppers it was the only one that killed them within minutes of contact nothing else worked very well.
