If the images aren't clear enough, you can zoom in by clicking them.
The high resolution images are in my dropbox folder above. In the last few days I've noticed the edges on my raspberry plants are turning brown and it doesn't seem to be improving. I originally suspected I over watered them (.5GPH drip emitters) Or that the leaves were damaged by a more concentrated spray of pyrethrin from a bad company that didn't make it clear that there were also petroleum products mixed in. Natural Pyrethrins only last a day and break down in sunlight.
More recently, I haven't pruned my tomatoes of excess leaves in 2-3 weeks and I've noticed some of the lowest ones dead and brown at the bottom. I know tomatoes are pest and disease magnets, along with being nitrogen pigs and its the last year I put up with such needy plants that need to be constantly staked up, tied, and trimmed for fruit that usually ends up being unsellable from damage or rots on the store shelves before it can be sold.
My main concern now is the tomatoes have infected the soil with Verticillium Wilt. Its not common but occasionally I'll have an eggplant or a pepper be completely healthy one day only to be wilted and die the next with the neighboring plants completely unaffected. Though I also suspect the previous land owners burned their trash in these "trouble spots" because I have found remnants of burnt wood and plastics. This being over the course of a few years. Tomatoes, squash, potatoes, and raspberries all tend to share the same pests but its never really been an issue with adequate trimming, weeding, not watering the leaves, etc. I had plans to put three, hundred foot rows of raspberries in after august when the tomatoes die and the weather cools but now its not looking good. It was supposed to be the start of a more permanent business so I could support myself and not be limited to growing cucumbers and other temporary non-sense.
Right now the plants are still alive, not-wilted, and green, save for the brown edges, the pictures were taken a few hours prior to this posting, but the stems have a fine blue tint on them which is associated with fungus and diseases. The tint may be part of the new growth, or it may be Verticillium Wilt but its not apparent enough to decide on. The color can be rubbed off though, so I suspect its fungus, all plants have new growth on them that seems unaffected.
The current raspberries planted are heritage and one lantham, the plants under the trees are separated from the garden by about 30ft. I need someone more experienced to assist me since this is only my second season at farming and I have little idea as to what it really it and only have my guesses to go on.
If you're suspecting a fungal issue spray them a copper fungicide. We've had a wet spring, and combined with the the damn-near 150% humidity I've had my share of fungal issues with my new trees. The fungicide I used, made by Bonide I believe, helped immensely for my plums, though I think it's time for a respray. Going to try a neem oil this time to handle it and aphids in one go around.
Bonide products are banned from my garden because they contain petroleum products, failed to function as intended, among other things. Cinnamon is an anti-fungal and a rooting agent so I may brew some if this problem persists but I would thing the plants would show signs of significant wilting or stress by now. I may be over reacting and its just mild fertilizer burn (3-4-3) or something, its called replenish and all organic. It may also just be damage or stress from putting them on the new cattle panels. All I can really do it monitor it and act as the situation changes.

Really? This stuff was labeled as safe for organic gardening. Guess that just proves the old adage about truth in advertising.
Now on the cinnamon does it have to be true Ceylon cinnamon, or the knock-off Chinese version most places carry? Being somewhat related I can imagine both may work, but I'm interested in knowing for sure

Ah! That's good to know. Gonna have to keep my eyes out for it next time. Keep us updated on the cinnamon, may be something I have to try depending on your results
This tropical storm has me wondering now if I should eat the cost of putting in post and cattle panel every eight feet, or go with putting posts every 20 and 40 feet and run cable or 550/750 cord for support of the canes. Almost everything in my garden got beat down by the wind but my rasps were fine.
Anyhoo, I guess that marks the end of the thread...
