I’m posting this just so I can keep track of what I have done so I’ll know next year.
On 12/2/17 I sprayed peaches, plums, apples, pears, jujube and persimmon with dormant oil, NuFilm P, copper and sulfur. I mixed them all in one sprayer and applied as labeled on each ingredient. You can really see the difference with the NuFilm. Looks like the tree has been shellacked.
You should probably get some other kind of copper if you are going through it that fast. I used Kocide 3000 and a bag last me 4-5 years. The dose depends a lot on the kind of copper. The spray amounts guide here probably has my Kocide dose in it.
Quince rust I found impossible to get rid of organically, its one reason I switched to myclobutanil for rust. Its horrible stuff, ruins fruits and can spread to apples (mine didn’t but I have seen it on local apples and its a mess).
I’m assuming since I wrote this with a small t, that is teaspoons (cap T is tablespoons usually). Which makes sense since the old spray was at the 5 teaspoon level and you want 28% of that for the more concentrated stuff.
