why do my apples have black spots?

Apples have black spots because they are infected with a fungus called black rot. The fungus enters the apple through wounds in the skin and grows in the fruit, causing the black spots. 

The black spots are actually dead tissue caused by the fungus. The fungus also causes the apple to rot from the inside, making it inedible. Apples with black rot should be discarded to prevent the spread of the fungus to other apples.

The black spots could also be sooty blotch also referred to as flyspeck. Sooty blotch is a fungal disease that affects the skin of apples. The fungus overwinters in infected leaves and debris and is spread to new apples by rain, wind, and insects. 

The disease causes dark brown or black spots on the apple skin. The spots may run together and cover large areas of the fruit. The fungus does not affect the flesh of the apple.

What is a fungal disease?

Fungal disease in apples is a condition that is caused by a fungus. This can cause the fruit to rot and the leaves to turn yellow. 

There are many different types of fungal diseases that can affect apples, including scab, powdery mildew, and cedar-apple rust. These diseases can be controlled with fungicides, but they can also be prevented by growing disease-resistant varieties of apples.

Is it safe to eat apples with black spots?

There is no evidence that apples with black spots are unsafe to eat. However, it is important to wash all apples thoroughly before eating them to remove any dirt, pesticides, or other contaminants that may be on the surface.

The black spots are usually caused by a fungus, and while they don’t make the apple itself poisonous, they can cause stomach upset if consumed in large quantities. In addition, the black spots can make the apple less appetizing to eat.

How can you prevent black spots in apples?

The best way to prevent black spots on apples is to grow the fruit in an area with good air circulation and to prune the trees regularly to promote good air circulation. 

The trees should also be sprayed with a fungicide every few weeks during the growing season. If the black spots are already present on the apples, they can be removed by scrubbing the fruit with a brush and water. The apples can then be treated with a fungicide.

The two main fungicides used to prevent black spots in apples are sulfur and copper. Sulfur is a natural element that has been used as a fungicide for centuries. It is effective against a wide range of fungi, including black spots. 

Copper is a heavy metal that is also effective against many fungi, including black spots. Copper fungicides are usually used in a mixture with sulfur. 

Both sulfur and copper can be toxic to people and animals if used improperly, so it is important to follow the directions on the label when using these fungicides.

How do you pick fresh apples at the market?

  • Inspect the apples for bruising, damage, and black spots.
  • Choose apples that are heavy for their size. 
  • Avoid apples with waxy or dull finishes. 
  • Tap the apple lightly with your fingers. A ripe apple will make a slightly hollow sound. 
  • Smell the apple. A ripe apple will have a pleasant, fruity aroma. 
  • Ask the vendor if the apples are ripe and ready to eat.

How to store apples?

Apples can be stored in a cool, dry place in a pantry for up to two weeks. You can also store them in the fridge. 

To store apples in the fridge, first, wash them with cold water and then pat them dry. Next, cut off any bruised or damaged parts of the apple. Finally, store the apples in a plastic bag or container in the fridge.
