GreenCure for Late Blight - Anyone ever heard of it?

rnewste · August 12, 2009

Came across this product at Harris Seeds. Claims it was invented at Cornell. Not read any discussion of it here on Tomatoville, so I thought I would post information on it.

Ray, here are the diseases that it supposedly controls and Late Blight ( P.infestans) is not one of them.

I really don't like an ad that just generally says molds and blights, etc. without being specific, so I went to the Green Cure site to get the above.

Here's some more on bicarbonate fungicides, in general...nothing mentioned about late blight here, either.

I looked at that a while back for my mold problem. A decent number of people said it didn't help them.

It seems if it worked for Lb Cornell would be listing it for suggested usage.

Actually it has more to do with rules, regulations and paying for certification than whether or not something works...

hasshoes · August 13, 2009

I don't understand. So people like copper companies pay for trials or something just so Cornell and extension services can say they are effective?

mjc · August 13, 2009

Let's use Bonide's Copper spray as an example. To be listed for a certain plant and a certain fungus it has to be tested on that combination. Bonide has to pay for the testing. This procedure is followed for each and every plant/pest combination that is listed on the label. And then there is a separate round of testing to become certified organic...

Things like Bordeaux Solution are sort of 'grandfathered in...they aren't usually approved for organic gardening, because they are 'DIY' products...you as the user assume all the risks/liabilities and as an unlisted/untested product you can't sell it as a fungicide nor can you keep organic certification.

I understand that. . . but Cornell, UMASS etc have rec'd chloranthinol (sp) or for organics copper. UMASS said that surprisingly copper has been working at some locations.

Now Serenade for example has Late Blight control listed on it. . . so if it is purely a "pay to play" scenerio then why aren't these places recommending Serenade?

And why aren't all the farmers being interviewed suggesting other things?

mjc · August 13, 2009

When did Serenade get LB listed?

Right now, most places are recommending things that have been listed for quite a while...

hasshoes · August 13, 2009

I thought it was listed on the bottle but I could be wrong. . . lol that stuff does give me an awful headache.

update: I just read the label online and it says it suppresses or controls late blight.

mjc · August 13, 2009

I hadn't noticed it when I've looked on it in the past...so I'm not sure how long it's been 'approved', but most of the stuff that the universities are recommending has had LB listed for ages...and there tends to be a sort of 'hide-bound' mentality that goes along with it, too.

Ray,

Nothing in the ad you post says anything about late blight control for this product.

barkeater · August 13, 2009

Just as I thought. The makers are trying to capitalize on the LB problem by insinuating it controls LB when nowhere does it say it. Basically it is only a powdery mildew control with a very limited effectiveness, if any, against other diseases. These are the diseases Greencure claims to have effectiveness against on their website:

Alternaria Blight
Anthracnose
Ascochyta Blight
Black Spot
Botrytis Blight
Botrytis Grey Mold
Cercospora Leaf Blight
Corynespora Leaf Spot
Didymellina Leaf Spot
Diplodia Tip Blight
Downy Mildew
Entomosporium Leaf Spot
Fusarium
Helminthosporium Leaf Spot
Ink Spot
Molilinea Fruit & Blossom Rot
Penicillium spp.
Phomopsis Blight
Powdery Mildew
Ovulinia sp.
Ramularia Leaf Spot
Ray Blight
Rust
Scab
Septoria Leaf Spot

And most of these have nothing to do with tomatoes

oops,

Sorry Carolyn, I didn't notice the link you posted to the "GreenCure" website.

hasshoes · August 13, 2009

MJC- what late blight suppressors and preventatives do you believe work that are not being suggested?
