Late Blight - Current advice on destroying infected plants

The Potato Growers of Alberta (who obviously have very real concerns about Late Blight!) have a very good (in this author's opinion) handout (PDF) on identification and handling of plants infected with Late Blight, including picture of diseased plant parts.  Of particular note is their advice on removing infected plants reproduced below for even easier reference (emphasis added).

The advice to bake infected plant parts using black plastic and the heat of the sun is reported to be very effective.  Key, though, is to dispose of the baked plant parts in the garbage to be buried in the landfill; DO NOT COMPOST them or put them in the City's Green Waste system.

As for protecting yourself against Late Blight, there is advice in our posting on the topic from a couple of years ago.

How to properly destroy infected plants

Potato and tomato plants with Late Blight on them should be promptly, carefully, and completely destroyed to avoid sending the disease on to other gardens or farms! 

DO NOT pull affected plant because this process can dislodge spores into the air where they can be wind-borne to neighboring plantings. 

To destroy individual plants 
* Pull a large dark plastic bag over the plant first. 
* Cut the plant off at ground level and tie the bag. 
* Put the bag in full sunlight so that the contents  will be killed by the heat from the sun. 
* Once the plant is dead, the fungus is also destroyed and the bag can be discarded with regular garbage. 

To destroy several adjacent plants 
* Cut the plant stems near ground level. 
* Promote destruction of the plants by placing a dark plastic cover over them so that heat from the sun will kill the tissue. 

Once affected vines and leaves have been destroyed, the potatoes can be dug and eaten, but better to eat them soon, as they will not store. 

DO NOT put affected potatoes in the compost pile because if they survive the winter, new sprouts from these potatoes could be the source of inoculum next season.
