are you in professional production .????

i find it hard to believe in my decades in the garden with all kinds of plants.. i have never needed to proactively treat anything against fungal infections ..

on the other hand. if you have 10,000 plants and your retirement depends on it ... that is another thing ...

any additional facts to support the use of chemicals???

No, I'm a medical writer by day and a compulsive gardener by night (or something like that).

I started using Phyton 27 years ago at the behest of the late Nancy Fiers of Mountain Maples. I used to have problems with verticillium wilt in my Japenese maples, and prophylactic use of Phyton 27 has been an effective control.

Since I've had fungal problems these past few years (thanks to 10 inch rainfalls and other erratic weather), I was thinking Phyton 27 might be a good preventive measure with problem conifers (mainly pines).

I have a bunch of the stuff in my garage and am feeling tempted. Or compulsive...take your pick.

where are you ... PNW???

I am wondering how a chemical, any chemical, used as a 'soil drench' can prevent mildew?
Mike....no mildew problems on conifers, and I live in the PNW

LOL Ken.

I wish I were in the PNW, but I'm just north of Chicago. The last 2-3 years have featured multiple "100 year rain" events.

The main ingredient in Phyton 27 is plain old copper sulfate...but it's super concentrated and bound to a salt conjugate that allows systemic uptake through the root system.

Sounds like nobody here has used it, so I don't think I'll risk it.
