Plant disease hits eastern US veggies early, hard, 7/3/09

Tomato plants have been removed from stores in half a dozen states as

a destructive and infectious plant disease makes its earliest and most

widespread appearance ever in the eastern United States.

Late blight the same disease that caused the Irish Potato Famine in

the 1840s  occurs sporadically in the Northeast, but this year's

outbreak is more severe for two reasons: infected plants have been

widely distributed by big-box retail stores and rainy weather has

hastened the spores' airborne spread.

The disease, which is not harmful to humans, is extremely contagious

and experts say it most likely spread on garden center shelves to

plants not involved in the initial infection. It also can spread once

plants reach their final destination, putting tomato and potato plants

in both home gardens and commercial fields at risk.

Meg McGrath, professor of plant pathology at Cornell University, calls

late blight "worse than the Bubonic Plague for plants."

"People need to realize this is probably one of the worst diseases we

have in the vegetable world," she said. "It's certain death for a

tomato plant."

Tomato plants have been removed from Home Depot, Wal-Mart, Lowe's and

Kmart stores in all six New England states, plus New York. Late blight

also has been identified in all other East Coast states except

Georgia, as well as Alabama, West Virginia and Ohio, McGrath said.

Plant experts are warning gardeners to be on the lookout for the

disease and to take quick action if it crops up. The first sign is

often brown spots on plant stems, followed by nickel-sized olive-green

or brown spots on the tops of leaves and fuzzy white fungal growth

underneath. Tomato fruit will show firm, brown spots.

Spraying with fungicides can control late blight if begun before

symptoms appear, but many plant experts recommend removing and

destroying the plants instead to prevent spores from traveling.

Obviously an internet search will yield more info on both the disease

and treatment.

milk

baking soda and water,

- a product called "Serenade" is suppposed to help with all types of

conditions,including Early and Late Blight, I have seen it for sale at

( Forgive me) Wal Mart, iam not sure where else it would be available.

it is a pre mixed spray, that is supposed to be safe to use right up

to harvest. It is available mail order from several on line retailer

as well. here is the link to the "Serenade" site. www.agraquest.com

- also note that tomato blight likes plants that are wet or in high

humidity conditions, and it's a soil borne problem that gets splashed

up on the plants - DO NOT water the plant, water the soil, and keep

the bottom leaves cut off so there's good air circulation under the

plants

- Some people have success controlling tomato diseases with cornmeal

or cornmeal tea. A gardenweb or google search will come up with some

interesting info.
