I got apricot, apple, peach, and cherry for trees that will eventually get sprayed.
Which of these should I spray anyway? And what should I use? I assume I want to still spray for fireblight
Im on long island to the extent that helps
I’d say for your apple, it depends what the local disease pressure is and what the resistance level of your variety is. Cedar Apple Rust and Scab affect the leaves. With CAR, if disease pressure is very high (like infected Cedars right next to it), even a “resistant” variety like Liberty may lose so many leaves that it may hardly grow. CAR is pretty easy to prevent with myclobutanil. I would just observe one season and see what is going on. Also, keep an eye on insect damage, may need a spray or pick off caterpillars.

Oriental Fruit Moths will tunnel into new growth of stone fruit and apples and cause wilted tips. That ruins the development of limbs on young trees. Check your Extension publications for time of emerging in your area.
I emailed them today and they told me they cannot advise me on spray schedules. Which seems bizarre. But ok.
They told me to hire someone with a license. Frustrating lol
