Hi and thanks for your question. Has this tree been newly planted? There is a lot to consider before applying pesticides! You will have to learn how to observe your tree and notice if there are signs of disease or harmful insects. In order to apply preventive pesticides you also need to learn the different stages of bud development-applying the correct pesticide at the correct time is crucial. The window of opportunity for dormant sprays is already past. I am also hoping there are other apple/crabapples in the area to pollinate your tree! The University of Missouri has a bulletin available online: G6010 Fruit Spray Schedule for Homeowners. If you google the number and title you will find it. Also, MSU has a handy publication that can be purchased at the bookstore: E-2720 A Pocket Guide for IPM Scouting in Michigan Apples. It costs $14. Both of these resources are a good place to start understanding your tree. The final resource is www.migarden.msu edu. The menu on the left has 'fruit' as a choice and you can explore that to get her more information. I hope this helps and good luck with your apples! Let us know if you have further questions.

Hi Marcia,

Thank you for the prompt response. The tree is over 20 years old, and we figured we should try to spay, nothing to lose. I will go through the sources you listed, and see what to do.

Thanks again,
