Daconil / Copper SettleMent

mobiledynamics · June 19, 2018

1st year using fung. to maximize crop.

Some observations. My sprayers - the bottom 4 corners has small divots - more like 3" oval depressions. Anyhow, with leftover Daconil and shaking it before spraying, the settled daconil does not budge, even after vigor-us shaking of it. Don't really notice it when the sprayer has liquid. More like after emptying it to rinse it clean, does one notice. Took a 2 Quart saucepan, boiled medium hot water, poured it in, let it sit for 20 seconds, shake. No dice. Emptied out the sprayer again and just used a strong pencil pattern on the hose nozzle which got rid of the settled daconil mix. A good analogy would be like wet cornstarch/flour. When it falls out of suspension even though in liquid, it's quite tenacious.

Since these fung. concentrates are technically a liquid product, I was not expecting the settlement

My copper sprayer I've yet to use up yet . Not sure if I will see similar/same behaviour.

Anyhow, like most chems, it looks like it may be best practice just to mix up what one may think they may use in a spray session and try ~not~ to have any leftover.

I did not mix alot as I know mix rotation/age is important. It's just interesting how the settled product is -conjealed --- bad description--, let's say it get's into a viscuous slurry, that settle in these divots. Shaking does affect it. Hot water does not affect it. A strong isolated blast does....which mean this stuff is thick and somewhat tenacious once settled.

For those more famiiar, care to share some info

Called Daconil. Mixed product is best with 24 hrs.

I thought I'd heard not to mix Daconil with anything, but I'm not sure of where that was said.

daconil and copper are in separate sprayers

Who will be eating this “maximized crop” treated repeatedly with systemic fungicide
Throughout the season?

I hate Daconil,I will never use it again.

Ging. I know ur a copper use. Same issues as OP. Or are you the latter- where best practice is to use up what you mix immediate.

Update. Copper spray can does not exhibit said issues. Just used up some that was mixed up about 1 1/2 weeks ago and doing the same rinse/cleanout, no traces of settled product on the bottom.
