Save your trees from Sudden Oak Death!
Easy to use combination: Simply mix 1.5 oz of Pentra-Bark, 1 quart (32oz) of Reliant and 1 quart of water for application with a garden sprayer. Treats 5+ mature, large trees. Reliant is a systemic fungicide with curative and protective activity against many pathogens of agricultural, nursery, greenhouse, landscape ornamentals, turf and lawns; it is quickly absorbed by plant foliage and roots and is distributed systematically throughout the plant. Once inside it turns on the natural defense mechanisms of the plant to resist invasion by disease causing pathogens, if diseases are already present it helps the plant to kill the pathogen invaders by curative activity while protecting new growth. Pentra-Bark penetrating surfactant will take Reliant into the vascular system of the tree for translocation into foliage and roots, maximizing the fungicide's efficiency and minimizing treatment times.

Very easy to use package includes Reliant which is the same as Agrifos and Pentrabark to get the mix into the tree faster. The mix covered 6 big trees no problem. Instructions were good and I did not have any problems with it. Thank you
Exactly the same as Agrifos for less money
This year, growing anything other than mosquitoes was pretty tough in PA. It went from a dry spring to one of the wettest summers on record.
My orchard was hit hard by Cedar Apple Rust (CAR) and Fire Blight. My orchard is young; some of the trees are only 3 years old. However, every one of them bloomed! (Hindsight tells me I should've pinched/picked off all of the blossoms to help prevent the blight. I've already cut down every cedar tree on the property.) I can live with CAR; it's ugly but it rarely kills the tree. Blight, however, is deadly - especially for a young tree! However, it kept raining and raining. In one week, I had dumped 9 inched from my gauge. In one night, we got 4 inches!
I couldn't spray any of the typical foliar sprays; there was too much rain. So, I was cutting blight-stricken wood out of the trees - 12-16 inches at a time - in an attempt to get rid of it before the disease reached and killed the root stock. When a tree, that's only 6 feet tall, is being cut down a foot at a time, it doesn't take long before you've got very little left to cut! However, still I couldn't get rid of the blight. I did one last pass with the pruners and I had 6 trees that resembled very short flagpoles; they had the lead and one small branch with one or two leaves on them. I had cut all I could from these trees... The next step was to rip out and dispose of the tree if this didn't work. But, I did my research and found Agri-Fos...
I ordered some of this and some Pentra-Bark and mixed up a batch for the basal bark application. I sprayed all of my trees - even those without blight - because they all had CAR. We got slammed with rain and I didn't go out to the orchard for 2 weeks. When I finally got out there, all my trees - that had CAR - still had it. However, you only saw it on the "older" leaves. All new growth was clear of any rust! It was the first time I had seen clean, green leaves on these trees.
The blight-stricken ones, that had been cut back to knee-high sticks, didn't have any leaves on them at all and looked dead. Oh, well, I figured I was going to lose them anyway...at least I had stopped the spread of blight to the other trees.
Several weeks went by and I had mowed around these knee-high "dead" trees several times... After about 6 weeks, these little dead sticks were sprouting new growth! They were free of blight and CAR! Now, I won't hold my breath but if they make it through the winter and come back in the spring, this stuff will be a true miracle drug for these trees.
