Backyard Berry Disease, Pest, and Cultural Practices Calendar

7/1/2019 (reviewed)
Authors: Ric Bessin, Kimberly Leonberger, John Strang, Nicole Ward Gauthier, Shawn Wright

Backyard berry (blueberry, raspberry, blackberry, and strawberry) production requires a proactive approach to disease, insect, and weed management. Preventative practices are recommended to minimize inputs. While intensive culture may result in the highest quality fruit, reduced inputs can result in acceptable fruit with minor crop losses or aesthetic maladies. This guide focuses on preventative cultural practices with options of low-input pesticide applications. Refer to the homeowner fruit spray guide (ID-21) for a more complete pesticide spray schedule.

Cane Diseases of Brambles

11/1/2017 (major revision)
Authors: Daniel Becker, Nicole Ward Gauthier

Anthracnose can cause severe damage to blackberries, purple and black raspberries, and to a much lesser extent, red raspberries in Kentucky. When left unchecked, anthracnose can significantly reduce overall yields, as well as limit the longevity of bramble plantings. Disease also causes loss of winter hardiness.

Blueberry Root Rot

5/1/2015 (new)
Authors: Nicole Ward Gauthier

Blueberry is considered one of the most disease-free fruit crops in Kentucky. Many of the diseases that affect blueberry result in minor damage. However, the most common disease of blueberry, Phytophthora root rot, can cause severe dieback and often results in plant death. The causal agent of blueberry root rot is Phytophthora cinnamomi, a soilborne water mold that occurs world-wide and can infect a wide range of hosts, including woody ornamentals. Under optimal conditions, the pathogen proliferates, and disease symptoms occur.

Black Rot of Grape

10/1/2012 (new)
Authors: Cheryl Kaiser, Nicole Ward Gauthier

Black rot is the most prevalent and one of the most important grape diseases in Kentucky. While this disease can affect all young developing plant tissues above ground, fruit infections are the most destructive. Without an adequate disease management program, both home and commercial vineyards suffer significant yield losses.

Strawberry Anthracnose

2/1/2012 (minor revision)
Authors: John Hartman, Nicole Ward Gauthier

Anthracnose can be a serious problem in Southern and Midwestern strawberry plantings. The disease may appear as a fruit or crown rot, both of which severely reduce plant stands and yields. Fruit rot, the most common form of anthracnose, appears as fruit begins to ripen in late spring. Crown rots, on the other hand, can develop in young plants soon after planting or when weather warms in spring.

Fruit Rots of Grape

10/1/2008 (new)
Authors: John Hartman, Cheryl Kaiser

Kentucky's typically wet springs and warm, humid summers favor the development of several fruit rots of grape. These include anthracnose, bitter rot, black rot, Botrytis bunch rot, ripe rot, and sour rot.

Downy Mildew of Grape

9/1/2008 (new)
Authors: Julie Beale, John Hartman, Cheryl Kaiser

Downy mildew is an important disease of commercial and backyard grapes in Kentucky. This disease causes direct losses when flowers, clusters, and shoots decay and yields are reduced. Indirect losses result when premature defoliation predisposes grapevines to winter injury. It may take a vineyard several years to fully recover after severe winter injury.

Poor Fruit Set in Brambles

9/1/2008 (new)
Authors: John Hartman

Poor fruit set and sterility commonly occur on bramble fruits (red raspberries, black raspberries, and blackberries) both in commercial and home plantings. Typically the fruit fails to develop or small misshapen berries form. When an insufficient number of drupelets fully develop, they tend to separate so that the fruit "crumbles" when picked. This symptom, referred to as "crumbly berry," is another common result of poor fruit set.

Phytophthora Root Rot of Brambles

7/1/2008 (new)
Authors: John Hartman

Brambles that are subjected to wet soil conditions or periods of flooding are often predisposed to Phytophthora root rot. Excess water not only promotes susceptibility of roots to this disease, but also aids the fungus in moving to new infection sites. Phytophthora root rot is primarily a disease of raspberries; however, it can also occur on blackberries.

Strawberry Fruit Rots

6/1/2008 (new)
Authors: John Hartman, Cheryl Kaiser

Strawberry fruit rot diseases often make it difficult to obtain high yields of quality berries. Kentucky's typically moist springtime growing conditions favor these diseases, which often begin with infections of flowers at bloom. Diseases causing the decay of developing and ripe strawberries include gray mold, leather rot, and anthracnose.

Blueberry Diseases

1/1/2008 (new)
Authors: Paul Bachi, Julie Beale, John Hartman, Sara Long

Kentucky blueberry growers sometimes experience plant and crop losses due to diseases. While most losses are due to root rot, or to stem and twig canker diseases, fruit rots and nutritional problems can also reduce yields. With good crop management, most blueberry diseases can be avoided.

Orange Rust of Brambles

9/1/2006 (new)
Authors: John Hartman, Chris Smigell

Orange rust is a disease caused by one of two very similar fungi, Gymnoconia nitens in the Southeast, and Arthuriomyces peckianus in the Midwest. Both fungi, causing the same symptoms, may be active in Kentucky. In Kentucky, orange rust is severe on some wild and cultivated thorny blackberries. It infects black and purple raspberries and thornless blackberries somewhat, but is not known to infect red raspberries.

Phomopsis Cane and Leaf Spot and Eutypa Dieback Diseases of Grape

11/1/2005 (minor revision)
Authors: Paul Bachi, John Hartman

"Cane and leaf spot" and "Eutypa dieback" were once thought to be the same disease. However, it is now known that each is a distinct disease caused by a different fungus. Grapes grown in areas where a moist environment persists are especially vulnerable to these fungal diseases.

Raspberry Fruit Rots

7/1/2004 (minor revision)
Authors: John Hartman

Rainy summer and fall weather in Kentucky can provide ideal conditions for fruit decay diseases of raspberries. The most damaging are the fungal diseases gray mold (Botrytis cinerea) and soft rot, or leak (Rhizopus and Mucor spp.). Both diseases are favored by long periods of wet fruit and foliage, and by high humidity levels. During some parts of the season, fruit rots account for up to 50% loss of potential harvest, and additional losses after harvest.
