@alan I have Avaunt and assail available, am I correct your 2nd/3rd sprays are Captan+Myclobutanil+Avaunt+Assail? You tank mix all 4? I’m spraying peaches and apples.
Thanks for the great resource.
yes

Actually for the 2nd, and usually final, insecticide spray, I replace myclo with Indar to get better control of brown rot for early ripening stonefruit.
Alan do you use a sticker with the dormant oil, myclobutanil and captan sprays?
I don’t use sticker with oil. Myclo doesn’t need a sticker, it is a systemic - Captan would be helped and I use a sticker for my summer brown rot and Marsonnina sprays.

Are there situations where you tank mix captan and mancozeb (captozeb) rather than captan and myclobutanil? Captozeb is mentioned in the yearly apple scab Cornell blogs.
No. Cornell doesn’t really offer expert advice for non-commercial growers and commercial ones tend to have a much larger problem of diseases developing resistance so it is much more important to vary controls.
I don’t use Myclo in my 2nd insecticide mix, I use Indar for the sake of the stone fruit that is in most of the orchards I manage.
which spray will control aphid, scale, white fly? it’s the early dormant oil or?
I’ve got a plum tree in fruit right now, green about half an inch fruit. but there’s ladybugs and a mantis cases or two and I want to get the aphids away without hurting the predators. I don’t think we have PC here.
what’s best to hit the tree with, if anything? it has no other visible issues.
I can’t get them all with the hose, the tree is too big.
would this be an accurate schedule based on this? I tried to condense it based on what I was reading. looking to try surround for my cherries/apples/peach (not gonna use it on serviceberry, I dont notice insect pressure on them at all, likewise not going to use hort oil on them, mostly going to give rust spraying a try).
No, the Surround usually needs to be tighter than that, at least 3 apps not more than 10 days apart. That is my own least spray possible for Surround, but I am no expert on its use. Only one of all my customers counts on Surround for protection. But it works well enough for her. You could also probably get away with Myclo only as a fungicide for apples, but for stone fruit you probably should use infuse for the 2nd and 3rd spray. Keep an eye out for brown rot though… that is a very low number of fungicide spray for the humid regions.

gotcha, so more often surround.
For brown rot, should i just default to higher spray on the stonefruit you think? Or start with this and eye it?
Do you think for serviceberry following the same schedule for apples without the surround is reasonable?
You don’t know your pressure if you take no risks and I’ve been able to rescue crops that start to get brown rot with Indar. I have no experience with the fungicide in Infuse but have read that it is almost as good.

Looking for feedback on this condensed spray recipe and schedule that I guided AI to construct. The dates reference timing of the Geneva facility, which I’m about 30 minutes from: Weekly Report 5/8/2025 | NY Tree Fruit Pest Monitoring Network
This is intended to be Alan’s recipe formatted for a 4 gallon backpack sprayer.
Differences:
- Add Manzate (optional) at the 3.0 lbs/A extended rate (I have apple scab issues)
- Replace Tactic with Nufilm at the extender rate of 8-16 oz/A
- Alternate insecticide modes of action (ArVida = neonic, Avaunt = oxadiazine)
Indar used pre-bloom because it’s stronger on scab, then alternating with Rally for cover sprays where Rally is stronger on powdery mildew.
It’s rounded to full spoon values only, and then back-calculated to determine the actual per acre rate at that rounded spoon value for a sanity check.
Alternating between Rally and Indar does almost nothing to slow resistance. They are in the same class of fungicides. I try to slow resistance by putting Captan in the same mix.
Nufilm has some advantage, perhaps in sun and rain resistance. There are subtle differences between them that make one better than the other on separate issues, but on all matters the difference is slight. However Nufilm is similarly packaged as far as volume and price.
I’m not familiar with ArVida, but Assail might be cheaper as it is an older formulation- if you are looking for a neonic.
