2016 Saskatoon Disease and Insect Pesticide Recommendations for Michigan Released

POSTED IN For Growers ON 3/15/2016

Michigan State University ExtensionWhat pesticide might help in controlling unwanted insects, fungus or weeds on, or around, your saskatoon bushes (Juneberries)? The members of the Saskatoon Berry Institute work with Duke Elsner, Small Fruit Educator, Michigan State University Extension to review their experiences with various products labeled for saskatoons. The results of that joint effort are included at: 2016 Saskatoon Disease and Insect Pesticide Recommendations.

Whether as a hobby, or a business, if you are growing saskatoons, you have probably run into some natural challenges to your optimal harvest. Common challenges for saskatoons include leaf spot, rust, rot, moths, weevils, mildew and aphids. Many of these are common to a variety of berries and other fruits. Especially with young plants (less than about 4 years old), weeds can compete with saskatoon bushes for water and nutrients. These issues can reduce the development of bushes and challenge the size of the harvest.

If you are new to growing saskatoons, and fruit in general, you may want to note that recommended pesticides vary by annual plant stages.

The recommendations are the result of seeking effective means of handling each of these challenges, and include “reduced risk” and organic options that have been found to be effective. Other sources of information for these recommendations include: Annemiek Schilder and Rufus Isaacs, both of The Center of Integrated Plant Systems, and both of whom made presentations to saskatoon growers as recently as this past winter.

To help improve the quantity and quality of your saskatoon crop, you may want to review How to Encourage Pollinators and Improve Your Crop, which was presented by Rufus Isaacs.

Many growers also experience challenges with birds. For this challenge, go to: Bird Damage and Management In Small Fruit.

For more information on the bud and bloom stages mentioned in the pesticide recommendations, and/or to help researchers better understand that timing of plant development, take a look at Saskatoon Bud and Fruit Developmental Stages.

Best wishes for a fruitful summer!
