How do you treat sooty blotch and flyspeck?
The blotches may coalesce to cover practically the entire fruit. The sooty blotch fungus is restricted to the outer surface of the fruit, and in many cases the blotches can be easily rubbed off. However, if infection occurs early in the season, you may need to rub or bleach the fruit vigorously to remove it.
What causes Flyspeck?
Flyspeck is a disease of maturing apples, caused by the fungus Zygophiala jamaicensis (also known as Schizothyrium pomi). ... The fungus responsible for flyspeck overwinters on apple twigs, but may be blown in from wild sources or other fruit trees for a period lasting up to two months around bloom time.
How do you treat flyspeck on apples?
Air currents dry the apples and leaves after a rain or dew, and dryness discourages the sooty blotch/flyspeck fungi. Mowing the grass and controlling weeds under apple trees also helps the apples to stay dry. Another key to good air movement is to thin the fruit load early in the season.
How do you treat Melanose citrus?
Citrus melanose control, once it has developed in a tree or orchard, involves the use of fungicides. The most common type used is copper fungicide, but you can get recommendations and instructions for use from your nursery or local agricultural extension.

Is sooty blotch safe to eat?
The conspic- uous symptoms of sooty blotch and flyspeck diminish the outward appearance of the fruit. However, neither disease will cause a serious rot, and affected fruit can be eaten safely. Sooty blotch and flyspeck are aptly named based on the symptoms of these diseases.
What is the best fungicide for fruit trees?
Systemic fungicides like Inspire Super, Vangard, Scala, Flint, Sovran, Merivon, Pristine, Luna Sensation, Luna Tranquility, Fontelis, Rubigan, and Rally are highly effective against many tree fruit diseases.
How do you prevent sooty mold?
Sooty molds can be indirectly controlled by reducing populations of sucking insects that excrete honeydew. Use the appropriate recommended chemicals that control aphids and other sucking insects.
What is sooty blotch on apples?
What is Sooty Blotch? Sooty blotch fungus is a common problem in apple trees with poor air circulation or where humidity is high during the cool season. The fungus Gloeodes pomigena is responsible for the dark, smutty discoloration that makes affected apples look impossibly damaged.
How do you treat apple scabs?
Planting disease resistant varieties is the best way to manage scab. Fungicides can be used to manage apple scab. Proper timing of sprays is needed for fungicides to control disease.
What causes dents in apples?
Damage caused by apple maggot
Apple maggot flies lay eggs in fruit and the fruit becomes pitted and misshapen. Each "sting” or hole created by the female fly as she lays an egg, forms a tiny spot or dimple. Pulp breaks down, discolors and starts to rot as a result of maggots (larvae) tunneling through the flesh.
How do you prevent black spots on apples?
Cultural practices and fungicides can help control sooty blotch and flyspeck. Proper pruning of apples trees and thinning of fruit promote drying and help reduce disease severity. Fungicides may also be necessary. If control measures fail, sooty blotch and flyspeck can be removed with vigorous rubbing.
