Tag: Erwinia tracheiphila

In Chapter 20, Sustainable Disease Management, on page 135 I said “Pathogens can infect the seed via several routes . . . Insects that feed on the plant can transfer the disease (striped cucumber beetles vector bacterial wilt, which is caused by Erwinia tracheiphila)”

It is true that striped cucumber beetles vector bacterial wilt, which is caused by Erwinia tracheiphila. It isn’t true that this disease is seed-borne. I don’t know where I got the wrong information from. I don’t yet know of an example of a disease spread by insects that can become seed-borne (that I feel confident about!).

I’ve asked my publishers, New Society, to correct that mistake next time they reprint. I wrote to the attentive reader, thanked her, and asked her for leads on where to find  information about seed-borne diseases brought in initially by insects.

Meanwhile, I can recommend two books on seed growing (that weren’t out when I wrote my book), that contain good information about which diseases are seed-borne. I reviewed the impressive The Organic Seed Grower by John Navazio a while back..

Newer is The Seed Garden: The Art and Practice of Seed Saving from Seed Savers Exchange and the Organic Seed Alliance. Including “advice for the home gardener and the more seasoned horticulturist alike”, this is also a book from people who work growing seeds, and know their stuff. I plan to review it one week soon (when the work pace slows a little!)

If you’re a seed grower, you might want to add one of these to your wish list. Both are beautiful books, as well as clearly written ones.

This year I am not doing quite as much seed growing as some years. For sale, we are growing Carolina Crowder cowpeas in our hoophouse. Click the link to see photos.

For ourselves, we are selecting and saving seed from our Roma tomatoes and Crimson Sweet watermelon, as well as West Indian Gherkins. We are also saving garlic and shallots for replanting.

It’s that time of year when I line up events I’ll be speaking at in the fall and winter (and to some extent, into spring). Here’s my plan so far:

Friday and Saturday September 11-12 2015

Heritage Harvest Festival, Monticello, Charlottesville, VA.

On Friday, 1.30-2.30pm I will be offering one of the Premium Workshops, Crop Rotations for Vegetables and Cover Crops.

That’s at the Woodland Pavilion, Visitor Center.

Then I will be doing book signing at the tent called The Shop at Monticello (at the Visitor Center), 2.45-3.13pm.

On Saturday I will be offering another premium workshop, Producing Asian Greens. This one is at the Vegetable Garden Tent at the Mountaintop (where most of the Saturday events are). It’s immediately followed by another book-signing, 5.30-6.0pm. The Festival ends at 6pm. All day Saturday is packed with events, and a General Admission ticket will be all you need apart from tickets for premium Workshops.

The following weekend, September 18-20, I will be at the Mother Earth News Fair, Seven Springs, Pennsylvania. The schedule is not yet firm, but I will be presenting The Hoophouse in Fall and Winter probably on Friday September 18 4-5pm at the Mother Earth News Stage, and The Hoophouse in Spring and Summer on Saturday September 19 10-11am at the GRIT stage.

I will also be signing books at the Mother Earth News Bookstore at some point and doing some scale demonstrations of string-weaving for tomatoes at the New Society Publishers booth.

The weekend of October 24-25 I plan to be at the Mother Earth News Fair in Topeka, Kansas with the two Hoophouse workshops. In February 2016, Mother Earth News is running their first fair in Belton, Texas.  Too soon for detailed information yet, but watch the site, if you live in Texas.

November 6-8 I will be at the Carolina Farm Stewardship Association Sustainable Agriculture Conference, in Durham, North Carolina. Click here for the Conference page. I’m doing two workshops, Cold-Hardy Winter Vegetables – on Saturday November7, 8.30-10am, and Succession Plantings for Continuous Harvests – on Sunday November 8, 10.45am-12.15pm. I will also do book signing at the BookSignAGanza, Saturday 5-6pm.

January 27-30 I will be at the Southern Sustainable Agriculture Working Group’s Practical Tools and Solutions for Sustaining Family Farms Conference in Lexington, Kentucky. On the website you can sign up for the e-newsletter and around October 15, you can do Early Bird Registration. I hope to be a speaker, but it’s too soon to say. . .
