Well, I'm relieved I'm not the only one with the erwinia problem...I was gone on a fishing trip for 10 days and when I returned, I found the outbreak throughout the greenhouse. It's pretty severe right now...I've been chopping off leaves, liberally using cinnamon, spraying with H202, and tonight will use the big guns recommended from a friend (2 ingredients, 1 gm per liter each). I've got Phyton 27, but was holding off on it as the last resort. I've used it in the past, once, without a problem.
In the last two days, the outbreak became more severe because the plants got stressed when the power went out for 3 1/2 hours. I was gone for a greenhouse open house and came home to find everything reset from the power outage and my temperature gauge showed the greenhouse climbed to 108 F when the power went out - which was what the outside temperature was at the time. I was surprised I didn't lose flowers or buds, but I was really surprised when sunken brown spots started appearing on leaves two days later. Some of the worst leaves were my multifloral species with two of them actually having leaking brownish-black liquid on the undersides.
I've got 5 days before I leave on a 5 month trip, so I kinda feel bad leaving the greenhouse in a friend's care while I'm gone because he's doing me a favor and now he's going to have to spend a lot more time watching things than planned. My wife does not have a green thumb though she tries.
On the bright side, however, I am quickly gaining more free space on the shelves in the greenhouse for more plants.
So, has anyone actually had any lreal uck stopping the infection on an infected plant?
