Re: [apple-crop] apple maggot
I would not use less than the label rate of 8 oz. per acre of Assail 30 SG. No consideration for TRV. And yes, if you have an extended AMF problem then re-application at a minimum of 10 days between sprays (depending on weather) is going to be necessary.

We have been able to control Apple Maggot at 1/3-1/2 rates with the OPs on about a 14 day schedule with monitoring using red sticky balls. Will Assail at 1/3-1/2 rate control Apple Maggot? Will the schedule need to be tightened up to 7-10 days? What about TRV?

Re: [apple-crop] apple maggot
We usually go 7 days after an application and then go by trapping for the next application.

Re: Apple-Crop: Apple Maggot
Art, I have used Assail for apple maggot control for several seasons now with very good results. I have been able to time our sprays so any second generation of codling moth is usually hit as well. We just did our AM spray about a week ago for this season. I usually do not include Assail in my first generation codling moth sprays so that I am only using it once per season. I use the Cornell Apple Maggot Monitoring form found at http://nysipm.cornell.edu/publications/apple_man/files/am.pdf and I use unbaited traps so my threshold is one fly/trap. I have never had to do a second spray for apple maggot. Hope this helps! Dennis Norton Royal Oak Farm Orchard 15908 Hebron Rd.

Re: Apple-Crop: Apple maggot in plums
I'm no entomologist, but my wife worked for Ron Prokopy for quite a while. If it were just plums, I'd think eastern cherry fruit fly, Rhagoletis cingulata, or maybe the black cherry fruit fly, Rhagoletis fausta. The coincidental occurrence with apple maggot makes it interesting. Maybe you're witnessing actual sympatric speciation in progress! Or maybe basing species differentiation on wing patterns and/ or host selection is not particularly meaningful when it comes to Rhagoletis. In any event, from a management perspective, rather than an evolutionary ecology slant, I'd recommend Baythroid or Asana sprays on both plums and apples. Good luck. Dan Daniel R.

Re: Apple-Crop: Apple maggot in plums
Lorraine, You might have a different species of Rhagoletes fruit fly instead of the apple maggot species. You might be able to obtain adult flies to ID by placing the infested fruit onto moist, sandy soil put a plastic bag in a box to allow the larvae to finish growing and then crawl out of the infested fruit and down into the moist soil to pupate. Once the pupae are formed, you can keep them in a cool room for a couple of months (some of our entomologist participants may have more info on specifics here), sieve the soil to harvest the pupae, and then store them at room temperature in a screened lid container to let the adult flies emerge from the pupae. Once you have adult flies, compare the wing patterns. The wing patterns for Rhagoletes species are pretty specific and comparison with wing patterns for the emerged adults should facilitate a correct ID.
