Carol Ann,

Tips to Prevent Overwintering Late Blight

Here are some tips for preventing late blight from coming back in your fields next year. The sheet can be found here as well: Tips to Prevent Overwintering Late Blight

Tips to Prevent Overwintering Late Blight

Late blight (Phytophthora infestans) occurs commonly each year in many places around the United States and the world.

There are steps we, as home gardeners, market farmers and commercial growers alike, can take in order to reduce late blight inoculum surviving the winter.

The following tips for fall will help prevent the spread of late blight (Phytophthora infestans). They are different from summer management techniques:

» If possible, start with new seed potatoes in the spring that have been certified disease free.

» Cull any potatoes that are suspect before putting them into storage - potato tubers with late blight will have a dry, reddish brown rot in the flesh.

» Turn soil in garden or fields so that crop residues can readily decompose - late blight needs live tissue to survive. This includes tomato crop residue as well. As long as tissues decompose or die (no living plant tissue), then the late blight on that plant tissue will be killed as well.

» Cull potatoes in storage throughout fall and winter months that are suspect.

» Try to dig up all possible tubers - cull volunteer plants that emerge in the spring.

» Cull piles should be thin enough to freeze solid over the winter.

» Cull piles can also be managed so that they heat up significantly - this is achieved by adding the proper mix of brown and green ingredients to your compost pile and turning. A compost thermometer might be helpful.

» In the northeast US only one type of late blight is found so all measures outlined above will help prevent late blight from overwintering. In some parts of the United States and the world two different types of late blight can be found in the same location thus allowing the pathogen to ‘mate' and produce oospores, capable of
surviving temperature extremes - in this case crop rotation is very important in reducing oospore inoculum on possible plant hosts. Crop rotation is important in all growing areas, no matter the size of your garden/field.

Thanks for all that info, Paul. I will pass it along to my hubby...he's the "farmer" in the family.

We have successfully over wintered a few spinach plants with out any protective cover. This year we are trying hoop houses over two rows of spinach.  This should be an interesting experiment. Here is one row with a heavy Agribon cover. Next month we'll install green house plastic. I guess we'll need to shovel a path to the garden to keep the snow off.

24.6 F this morning, first hard freeze this fall, PA Zone 5B, so the official growing season is over.

Under the low hoop house tunnel it is 28.9 F. Spinach has frosty leaves and mesclun we planted a few weeks back is coming up.

I received Elliott Colemans Winter Harvest book and it's excellent reading for hoop house growing.

First hard freeze for my area was also Friday into Saturday.  First hard freeze always causes the mulberry leaves to disconnect and fall as soon as the sun comes over the ridge.  It's kind of fun to watch.  There have been years when it's like a deluge and they all drop off within 15-30 minutes.  Other times, like Saturday morning, they just release and slowly shower down over about 1-2 hours.  Either way, the tree is bare by the noon hour.

So, we're officially on the slide toward winter.  I don't suppose we could skip it this year.  I know my heating bill would appreciate it.

I always seem to get depressed about the loss of the summer leaves, until the trees are bare and I realize they are a thing of beauty without leaves! Plus I get my view back of Camelback Mountain and the ski runs. I believe last year at this time Camelback was already making snow and they opened for Thanksgiving.

Added on edit, last year 11/17 they started making snow around here. http://forums.delphiforums.com/olt/messages?msg=1832.1

Just walked out of the office and we have the first snow of the season!  Welcome December!

This was our first cold rainy day. I doubt we'll see any snow here in the south.
