Fungicide

I am having a problem with some type of fungus/bacteria in my yard. Last year it affected my tomatoes and I 'self-diagnosed' it as bacterial speck with no effective control measure. This spring after like 14 days in a row of rain, it has spread to other plants. After some further 'research' I'm thinking it's a combination of spot anthracnose, septoria leaf spot, and gray leaf spot. With the chance this is a fungus and not bacteria, I'm hoping maybe I can control/prevent major damage to my beds. Of course the internet has numerous fungicides listed, but I want to know if anyone knows of a specific one that does well. I am also interested in any "organic" fungicides; I have heard of things like baking soda or milk. I did fall clean-up, didn't compost infected plants or anyones near, stayed out of wet leaves- but with all the rain there's nothing I can do (although it was finally hot and sunny this weekend !!). I have to figure something out to keep this from devastating my yard.

I have used Neem oil and Safer fungicide before with good results. Here is a link to a number of products.

daconil is good.

I have some Daconil but haven't had any good experiences with it. It doesn't seem to work well and it's too thick. I always want to water it down, but I don't think it would be as effective as it's suppose to be. What diseases have you used it for?

Any type of fungus. The pre mix isn't worth a flip. Buy the concentrate and you'll get better results.

Concentrate kocide for the anthracnose. I use it on my Julie dwarf mango because it is susceptible to it.

I used that Daconil for the first time this year on a fungus that started out for the second year on my dogwoods. It was recommended by our local gardening guru, Walter Reeves. It was a nightmare trying to spray it. It is so thick! Although it was expensive, I wanted to save the blooms and leaves from discoloring and curling, so I bought another bottle to see if it was the sprayer... but it wasn't. They need to do something about that formula. It was a nightmare trying to cover two ten foot tall X ten foot wide dogwoods. I did my best, but know I didn't even come close to getting everything covered. There's no such thing as "spraying" with this stuff. It's way to gloppy! I'll never buy it again. It really aggravated my carpel tunnel. If you can, find a substitute for this very specific fungicide.

Edited for spelling, as always :-)

not any help for this year. But get rid of all tomato plants at the end of this year, anything with this fungus on it. Do not till in the plants in the ground. Next year trying planting with landscape fabric underneath; alot of blights come from the ground. Or try planting is a totallly different area. If it is blossom end rot- calcium is the trick. If in a pot, use tums, or use gypsum in the beginning of the year. Or use epsom salt and non fat milk.

For blight try: 15 parts soft soap, 29 parts sulfurated potash, and 1,000 parts water. Pick off any heavily infected leaf, discard totally do leave around or will infect others.

The only thing i know for now that is useful is daconil. Concentrated works better for me.

3gardeners: You said the kocide is...thick? At what water:kocide ratio were you spraying it? Surely it is thick in its concentrated form, but by the time you heavily dilute it per instruction on the bottle, it should be the same relative consistency of water. I think I barely used a half a cap-full per 2 gallons of water, but I can't quite remember exactly. Also, are you using the powdered or the liquid stuff?

I bought the Daconil in their Ready-to-Use spray bottle. It's red. It has their sprayer on it. Just for the heck of it, I put some in my sprayer to give it a try. It wouldn't even come out of it. So I put it back in their bottle and toughed it out. I had to get it on my dogwoods and I'd already bought 2 bottles by then. But I won't buy it again though. The blooms did look better, but they were on the trees for a very short period this year. I don't know why. Other than that, the trees seem to be doing fine.

My Daconil can of concentrate, mixed with water (as directed), sprays very well from my Hudson gallon and a half tank pressure sprayer. You do NEED to shake it well before using.

I would never try this product with the spray nozzle on top.

pbyrley,
I think you are 4 years too late with your answer. LOL!

Yeah, I knew that, just wanted to add my vote against the (expensive) spray top product.
Daconil is a widespread product and somebody else beside me may search it next year.
