PPFS-FR-S-5

Strawberry Anthracnose Fruit and Crown Rot

3/22/2021 (major revision)
Authors: Nicole Ward Gauthier, Shawn Wright

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.

Rust Diseases of Brambles

1/5/2021 (major revision)
Authors: Nicole Ward Gauthier, Jessica Sayre

The three most important rust diseases occurring on brambles in Kentucky are cane and leaf rust, late rust, and orange rust. The most destructive of these diseases is orange rust, which is ultimately lethal to plants. Once infected, entire plants must be removed and destroyed. In contrast, cane and leaf rust, along with late rust, are not lethal to plants and can be managed using cultural practices and fungicides. Distinguishing between these rust diseases is critical for proper management.

Cultural Calendar for Commercial Strawberry Production

5/27/2020 (new)
Authors: Ric Bessin, Nicole Ward Gauthier, Kimberly Leonberger, Matthew Springer, John Strang, Shawn Wright

Inegrated pest management (IPM) includes the combination of biological, cultural, physical, and chemical tools in efforts to manage diseases and pests while minimizing risks associated with pesticides. Cultural practices are an integral part of an IPM program and should be incorporated into all commercial systems whether large or small, conventional or organic. This publication provides recommended practices at approximate growth stages and/or production periods. However, these timelines are approximate and may require adjustment for particular conditions. Growers who encounter situations that may not align with suggestions here should contact their county Extension office for assistance.

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.

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.

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.

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

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.

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.
