Is there anything practical that can be done? My couple of container-grown
'Patio' tomato plants produce loads of tomatoes, more than I can use
actually, but they all invariably develop the typical sunken then darkened
spots of anthracnose at about the time they ripen properly. Even those that
look OK quickly turn when brought into the kitchen. I use fresh commercial
planting mix every year so the disease should not be from that source. All
I can figure is that it is 'in the air' since we have had a large
percentage of our native dogwoods succumb to anthracnose in recent decades.
Every year is seems that some plague or another attacks my tomatoes -- I'm
about ready to give up on fresh tomatoes.

I thought that I had it bad until the hornworms showed up a couple of days
ago. The first sign was grooves eaten into the surface of first one tomato
then a couple more. I found a couple of the nasty little things (well not
so little actually -- one was the size of my index finger) and killed those
manually and then I broke out the dusting gun and treated the plants. I
dislike using insecticides but if the tomatoes are going to last long
enough to be ruined by anthracnose I had to do something...
