Wettable Sulphur
Copper
Captan
Rally
Prophyt (for fungus)
Bonide Fruit tree spray

This is for pears, apples, peaches, newly planted cherry. I should be past petal fall. I am thinking Captan for Apples and peaches. Sulphur for pears. Good? Bad? Can I spray the apples and peaches with Sulphur so as to make it lots easier..??

Comments??

Thanks.

Do oil spray somewhere between the point where emerging shoots are 1/2" and the flower clusters begin to show a lot of pink. Mix Rally or Immunox (myclobutinol) at highest legal rate with 1 to 2% oil. If it's closer to pink use 1%.

Don't spray again until petal fall when petals have mostly gone from latest flowering varieties and bees have lost interest. Than spray Imidan (or triazide or something equally affective) + Nova + Captan mixed together at highest legal rates (you may want to drop the Captan because of increasing concerns about health risks). Repeat in 10 to 14 days.
Where I manage orchards, the space between earliest flowering Japanese plums and latest flowering apples is only 2 weeks or so (not this year) which usually allows me to wait until the latest flowering trees are ready to begin spraying anything. Plum curculio seems to time its appearance conveniently to the rhythm of the last flowering apple varieties. This may not be true where you are.
If plums or peaches need oil they may need application before apples. I�ve only had mites on European plums here and never need oil for other stone fruit.

All this is based on plum curculio being the primary insect problem which is the case most areas east of the Mis. River. These sprays will also absolutely control scab, CAR and Mildew as well as most of the crop fatal insects. Apple fly maggot is an exception, but I haven't had much of a problem with this pest in the orchards I manage. This pest can be controlled with a lot of fake apples smeared with tangle trap.

If you don't want to use synthetic chemicals try 4 applications of Surround about a week apart starting at petal fall. You may need to start on earlier flowering varieties as soon as they drop petals. When weather isn't too hot you can mix hort oil at 1% once or twice.

Stone fruit may require the addition of an application or 2 of Indar (Monterey Fungus Fighter is a similar chemical available in home orchard quantities) starting 4 weeks before first peaches ripen. Apricots must be sprayed sooner if they are scab susceptible with same compound.

Because I manage so many orchards so far apart I have to resort to a spray schedule that is based on expectations rather than actual monitoring. You may be able to reduce insecticide sprays with monitoring but PC can enter an orchard overnight and, if your insecticide lacks kick-back, which Imidan has, do a lot of damage in a couple of days.
Other problems may occur later in the season and you will in time learn to monitor and react to the pitfalls.

Good luck, Alan Haigh- The Home Orchard Co.

How are you predicting sprays on such an awkward year like 2012?
Blossom orders are shuffled in some places, this cant make your job easy.

I am struggling to figure this year out. Southern growers always have a long period between first and last bloomers as I understand it- they need have an early blooming apple to pollinate another early bloomer. Here there's usually enough overlap that any apple will pollinate another.

This year there's been more gap, but worse, the late bloomers have held blossoms for almost 4 weeks. I still have a few trees on sites that I haven't sprayed yet and I've had to make extra trips and many more sprays. There's no rhyme or reason I can make out why same varieties like Goldrush are holding on to their flowers on one site and done on another with less exposure where the opposite would usually be true.

I have no idea what the plum curculio are up to or if they've starved out. I haven't seen much damage at all.

There are no aggravating tiny flies that are usually in your face here by this time either. Always an upside somewhere.

Maybe he had years like his one when mother natures helped kill off the insects so there were fruit to eat back then...just a guess and I know the season still early...lol!

Thanks Harvestman for listing your spray program.

Maybe someone with actual experience with this method can post something.

as for spray scedules in wi...that can vary widely depending on where in wi you are...if there's a cps location near you that's where i'd start. or extension.

What isn't clear is how many flies the traps don't catch.

Cornell doesn't do research on growing fruit in home orchards, where fruit doesn't have to be pristine and pest pressure tends to be less than in huge orchard monocultures. Both Cornell and Rutgers, the NJ source of extension info, provide unreliable info on fruit pest control for home growers.

I can't speak for other states, but none of them has a mandate or enough funding to do research and distribute legitimate info for home growers beyond trying to stop them from poisoning themselves or the environment. They usually recommend pre-mix fruit sprays and often malathion with too large intervals between sprays. They tend to me unaware of newer, safer and more affective formulations such as Triazide and Rally.

The best thing to do, IMO, is start with a 2 insecticide program if you are in about Z7 or colder and see what happens. Then you can find out what the sweet spot is and if trees are young, not risk much fruit in the process. Or better still, don't spray the first crop at all and identify pests as they appear, sacrificing a small amount of fruit for your education.

That is, if you can't get info from a nearby grower who seems competent. If I lived near Scott, for instance, I would expect to have problems with Oriental fruit moth, which would greatly complicate a spray schedule beyond what I currently have to do. It's a pest that's becoming a greater liability in my area and may soon increase the number of necessary sprays here.

I used to have a problem with OFM deforming nursery peach trees after my low spray was over (they attacked shoots but not fruits). For a while there was a company that sold a pheromone bait formula with a pyrethroid bait that is extremely affective for me. I still have some bait left but it's been taken off the market for some stupid reason.

Might be a good idea for somebody in the northeast to save this thread on their computer. Every year there are new folks who want a spray program. For those in the NE, this would be a good thread to point them to. The thread would do them more good than Extension literature.

I do have the advantage of managing multiple sites, but that is not as important as it would be if we all didn't have good access to each other through the internet.
