What to spray on my cherry trees?

Last year I had little white worms inside most of the cherries. What should I spray on my cherry trees to prevent that this year?

Update:

Raid is not to be used on food. There must be chemicals available to use on orchards

    Dormant oil and Bonide are usually used.. It is too late for the oil because you usually spray that in very early Spring. You should spray the Bonide which contains the pesticide captan immediately after the tree flowers. There are many other approved sprays for fruit trees and it is best to let you look at this guide . It will give you all the information that you will need. Yet this is for the USA and I am not sure what chemicals are approved in Canada. So you will have to look through the list of chemicals to see which is approved where you live.

    There is this one site for organic fruit tree care located in Ontario so it may help you also.

    You spray on an analogous time as this is till at last in bud. you do no longer opt to spray whilst the flowers open reason you will kill off the critters that would pollinate it. you may spray returned after this is totally performed blooming in spite of if this is the till now that does the final.
