Ed, this post of yours has made me think about what I have been doing.
I had some spreader/sticker years ago. When I used it all up, I went without. I have been using a very small squirt of dish soap which should be a good spreader. It does nothing in the "sticker" department of course. Friday was a clear calm day and rain was expected on Saturday and Sunday so I did my first Imidan spray then rather than wait any longer.
Between Alan's question and your answer I suddenly realized that the soap might actually assist the rain in washing off the Imidan (and other sprays I will use later in the season). I guess it's time to invest in a new product. Nu-Film 17 seems to come only in gallon size and that will last me a very long time. Maybe I'll just buy it anyway and then I will have it when I need it.

Al:

     To deal with the situation below regarding the efficiency/adhesion of Imidan (and others) I'd suggest the use of a sticker/spreader/UV inhibitor.  Nu-Film 17 was my choice years back and there may be others which have the same capacity to do the job.

     I could easily get 14 days of protection from Imidan using it.

This question is addressed to the experienced applicators out there.  Unusually cool spring weather has altered and extended bloom period considerably here in Z.6, SE NY.  It creates quite a dilemma on the decision of when to put down first insecticide application when the first apples to set on a given tree are being ravaged by curculio while there are still unopened blossoms on the same tree.

 

In the past I've been able to wait until the latest flowering apple varieties drop their petals to make first Imidan application to all species in mixed fruit orchards and have avoided serious curc damage even on the earliest plums.  To further complicate matters, frequent showers are limiting the opportunity to set spray.  I need at least an hour of good drying conditions following spray to have any confidence of adhesion. 

I'm not even sure this is enough time and I'm interested in the experience of some of you veterans on this issue.  How much setting time before rain seems to be required for Imidan?  How heavy a rain will erase the application before it sets?  I already know that mist and drizzle are fine but a specific number like 1/8th an inch would be useful. Thanks
