Red Tip Fungus

Question

My parents have an enormously high row of red-tip photinias that shield their property from a cotton field. They have lost at least one plant over the past few years. The plants lose their leaves and eventually die. My parents are concerned that this will eventually spread through the entire group of plants. What can they use to kill this fungus?

Answer 1

Using a fungicide called Banner Maxx or its generic and cheaper form called Honor Guard should do the trick. There is also a product called Mancozeb that works very well. The Mancozeb will leave a bit of yellowish powdery residue on the foliage which is part of how it works.
