Another fungicide

sneezer2
15 years ago

There is another "organic" fungicide available besides

Serenade Max. I've spent a few minutes researching this and

am posting it now for those of you who may wish to follow up

for next year.

I've been using a copper soap along with Serenade Max and

find the combination quite effective. The one I have is

called Soap-Shield from Gardens Alive and, for them, is

actually not terribly expensive. You can look it up on their

site. I'm not buying it now as I have most of a gallon

left that I bought quite some time ago.

The active ingredient is copper octanoate, which is

certifiably organic for those of you to whom that makes

a difference. Google that chemical name and you will

find a number of manufacturers and sellers of similar

products. Some are concentrates and that, to my mind, is

the way to go. Others are ready to use spray bottles,

which makes it very expensive, mostly water and expensive

to ship. The concentrates can be either 10% or 8% active

ingredient.

The one that appears to be most economical, at least if you

are shipping to eastern states is called Liqui-Cop. and

is available from Biocontrol Network in Tennessee:

at $14.70 a quart and $9.76 shipping. Shipping gets

relatively lower if you order more.

Liqui-cop is also available from Outside Pride in Oregon:

http://www.outsidepride.com/catalog/Liquid-Copper-Fungicide-p-17969.html

at $16.99 a quart and $9.60 via UPS or $7.75 priority mail.

Liqui-Cop is an 8% concentrate, while Soap-Shield is 10%

Bonide makes a 10% concentrate that they call Liquid

Copper Fungicide, which sells for about $15 per pint at

a variety of outlets.

One benefit that I have had from doing this research is

to see that recommended application rates may be much

lower than I had thought. Gardens Alive recommends about

2 oz. per gallon of spray. Other recommendations appear

to be much lower. I haven't yet looked at that in detail

but suspect I may end up using a lot less than before

as an early preventive measure and especially as I will

be using it with Serenade Max as well.
