Backyard Apple Disease and Pest Management Using Cultural Practices (with Low Spray, No Spray and Organic Options)
6/1/2016 (new)

Backyard apple 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. | PPFS-FR-T-21

Simplified Backyard Peach and Stone Fruit Spray Guide
4/1/2016 (reviewed)

Peach, nectarine, apricot, plum, and cherry are all stone fruits. Production of these tree fruits requires pest and disease management programs for quality fruit. Home orchards are no different. Homeowners, however, are generally more tolerant of aesthetic maladies or minor crop losses than commercial orchardists. Thus, homeowners may choose to limit numbers of insecticide and fungicide sprays. Disease resistant cultivars are the preferred method for reducing spray inputs. | PPFS-FR-T-20

Cherry Leaf Spot
3/1/2016 (new)

Cherry leaf spot occurs on both sweet and sour cherry; however, it is considerably more serious on sour cherries. Premature defoliation from cherry leaf spot reduces flower bud set for the next year, weakens trees, and increases sensitivity to winter injury. | PPFS-FR-T-6
web only | 1 pages | 311 words | 5 downloads | PDF: 500 kb


Frogeye Leaf Spot, Black Rot, and Canker of Apple
2/1/2016 (new)

Black rot and frogeye are common names of an apple disease that occurs in three phases: (1) leaf infections result in frogeye leaf spot, while (2) fruit rot and (3) branch infections are referred to as black rot. All three phases can cause significant damage in Kentucky home and commercial orchards. | PPFS-FR-T-3
web only | 3 pages | 785 words | 3 downloads | PDF: 1,003 kb


Black Knot
12/1/2015 (new)

Black knot is a common, often serious, disease of plums and cherries in Kentucky. Ornamental Prunus species, as well as wild plums and cherries, may also be affected. Trees in both commercial and residential plantings are susceptible. | PPFS-FR-T-4
web only | 2 pages | 617 words | 2 downloads | PDF: 784 kb


Peach Leaf Curl and Plum Pockets
12/1/2015 (new)

Peach leaf curl occurs annually in commercial and residential orchards throughout Kentucky. The disease causes severe defoliation, weakens trees, and reduces fruit quality, fruit set, and yield. Peaches, apricots, and nectarines are susceptible to peach leaf curl. Plum pockets is a similar, but less common, disease that occurs on wild and cultivated plums. | PPFS-FR-T-1
web only | 3 pages | 667 words | 3 downloads | PDF: 887 kb


Gummosis and Perennial Canker of Stone Fruits
11/1/2015 (minor revision)

Gummosis is a general, nonspecific condition of stone fruits (peach, nectarine, plum and cherry) in which gum is exuded and deposited on the bark of trees. Gum is produced in response to any type of wound, regardless of whether it is due to insects, mechanical injury or disease. | PPFS-FR-T-8
web only | 2 pages | 559 words | 4 downloads | PDF: 207 kb


Apple Rust Diseases
8/1/2015 (new)

Cedar-apple rust is the most common and economically important rust disease occurring on apple in Kentucky. Two other rusts, cedar-hawthorn rust and cedar-quince rust, are of lesser importance on apple, but can significantly impact ornamental plants. All three diseases occur on crabapple, hawthorn, mountain ash, pear, and serviceberry. | PPFS-FR-T-5

Apple Scab
8/1/2012 (new)

Apple scab is the most consistently serious disease of apple and flowering crabapple in Kentucky. This disease also occurs on hawthorn and mountain ash; a similar disease affects pear and pyracantha (firethorn). The most noticeable losses on apple result from reduced fruit quality and from premature drop of infected fruit. Scab also causes a general weakening of the host when leaves are shed prematurely. Summer defoliation of flowering crabapple due to scab invariably results in fewer flowers the next spring. | PPFS-FR-T-13

Fire Blight
8/1/2012 (minor revision)

Fire blight is a highly destructive disease of apple and pear that can occur in commercial orchards and home plantings. Many landscape trees and shrubs in the rose family are also susceptible to this disease. Fire blight can cause severe damage in a very short period of time. Because precise conditions are needed for infection, disease appearance is erratic from year to year. | PPFS-FR-T-12
web only | 4 pages | 1,556 words | 5 downloads | PDF: 650 kb


Peach Fruit Diseases
6/1/2007 (new)

Peaches are grown in many Kentucky orchards for local fresh market sales. Fruit diseases, often resulting in decayed peaches, are a serious problem, especially during warm, humid, rainy weather conditions. | PPFS-FR-T-9

Apple Fruit Diseases Appearing at Harvest
8/1/2004 (minor revision)

Diseases of apple fruits appearing at harvest can cause significant losses in yield and quality. To know what control measures to take next year to prevent similar losses, it is important to recognize what is being observed. In some cases, growers will need to cut the fruit open to identify the problem. | PPFS-FR-T-2
