Daconil question

[duajones]

OK, I'll go. For the daconil proponents on the forum. I know you guys get bombarded with questions concerning daconil. My current regimen is to spray plants once a week or every 10 days,with a solution of 1 tbsp per gallon of water, repeating after a good rain. I spray every bit of the plant I can including stems and the mulch under the plant. If you have a good rain and it continues to rain on and off over a period of a few days. Do you reapply every chance you get once the plants have dried? Or do you wait until the rain has pretty much subsided to re-apply? Also, Is it beneficial to spray the mulch in the whole bed, or just directly under the plants?

P.S. I probably should have posted this under common disease and pest, but didnt think about it until I had already posted

It depends. If it's just going to rain and rain (like it's doing here right now ), seems pointless to waste it. Usually I just wait.

On the other hand/for example, if there's three days of rain, then two dry days with more rain forecasted afterwards, I will generally try and spray in between those two rains.

In short, it's a judgment call.

No need to spray anything but the plants themselves. Daconil works preventatively by sealing the attachment sites for fungal spores on the plants.

Hmm. Now I can't remember who was saying to soak the mulch with daconil as well. But since it only works on the plant, I guess that would be pointless.

Edit: 1 tbsp per gallon!

It's one tablespoon per gallon for the 'standard' ~29-30% formulation.

I have a bottle of GardenTech Daconil Fungicide Concentrate. It is 29.6% concentration.

For tomatoes, they recommend 1 tbsp (3 tsp) for 1 gallon of water for control of Early Blight, Late Blight, Gray Leaf Spot, Gray Leaf Mold, Septoria Leaf Spot, Anthracnose (fruit rot), Alternaria Fruit Rot (Black Mold), Rhizoctonia Fruit Rot, and Botrytis Gray Mold.

I think I bought mine from eBay, and it's 23%

Seems like it may have been Earl that mentioned spraying the mulch when he plants.

I have found that Daconil spray seems to slide off hairy leaves easily.
Do you think it would be a good idea to add some laundry detergent as wetting agent so that it can cover better?

The formulations I use/recommend already have a spreader/sticker included; hard to say about the one you purchased from ebay. What does the ingredients list indicate?

[Mantis]

Try adding a squirt of PVA glue D. Should stick then me thinks

Laundry detergent should NEVER be used as a wetting agent for spraying plants. Laundry detergents often contain optical brightening agents, silicates, dyes, salts such as sodium hexametaphosphate, sodium carbonate, sodium borate etc.

Good for getting your laundry clean? yes.

Good for your garden? no.

Good to eat? a big double no.

The same goes for using automatic dishwasher detergent. This stuff is actually very poisonous.

Hand dishwashing liquid is generally recognized as safe.

dcarch, Suze already mentioned the Daconil with spreader/sticker which should adhere to your hairy leaves. My heavens I never had trouble with Daconil and hairy leaves.

If you can't get Daconil with spreader/sticker locally you can buy the latter separately and add it. It's concentrated so it won't change the concentration that much at all. And spreader stickers have lots of uses for garden and orchard use.

And concentration is important, as I found out when I called Ortho a few years back.

And yes, Daconil comes in many different formulations and percentages and as I remember, they were also described or listed at the Ortho site.

Different pathogens and different uses for different reasons require those different concentrations, which can range up to 70% chlorothalinol.

But it's the 29% product that is recommended for tomato foliage pathogens so that's what one should buy.

I remember so well one person many years ago saying that Daconil didn't work at all and it turns out he was using the 12.5% one, which is useless.

Mind boggling how much you can learn from here!
Thanks All.


Once I've learned as much as Mantis, then I too can ignore you all. (As Mantis has so declared on another thread )

Regarding spreader/stickers:

The label for Indicate5 does not say whether it's acceptable for use on vegetables. I haven't used it with my Ortho Daconil product because, as Suze mentioned, it already contains a spreader sticker. I use it with the fungicides that I use on my roses and it seems to work great. It is supposed to adjust the Ph of your spray water to an optimal level and it contains a spreader sticker. Their research states that it greatly increases the length of effectiveness of your spray products.

Do any of you have any exprience with this product?
