Tomato pesticides, anything better than Malathion?

But that black growth sounds suspiciously like blight - which no amount of insecticide - or fungicide, for that matter - is going to cure. If that's really what it is, there isn't much you can do except remove affected leaves and fruit and hope it only spreads slowly. However, since blight thrives in humid conditions you should probably cut down on the spraying too. I wonder if a sulfur treatment would help? Bordeaux mixture should work, and it even sticks pretty well through rains. Bob I'm not familiar with that. I'll have to google it... Copper sulfate and slaked lime. I think it's even "organic" approved. Bob It makes sense. I may have to try some of that for the ivy out front. Your ivy has a fungus? Bordeaux mixture is a fungicide; it sounded like OP's tomatoes have a blight. Fungicide will help. BTW, my one tomato plant that's downhill from the compost pile (where among other things I've been dumping the cat box) is big and robust and 3 times the size of the other tomato plants. It's also the only one that doesn't have any blight at all. Coincidence? Bob |

It kills whole sections before I catch it. :-( Bordeaux mixture is a fungicide; it sounded like OP's tomatoes have a blight. Fungicide will help. I can use topical fungicides for my Peruvian torches. They came in with a blight and I've been fighting it ever since.

Bob Good nitrogen in that cat litter. ;-) It used to be beneficial here too, but I quit dumping used kitty litter in garden beds when I switched to scoopable.
