Phyllachora pomigena is a tiny fungus that causes a plant disease. It is a type of plant pathogen, meaning it can make plants sick. This fungus is known for causing "Sooty blotch and flyspeck" disease. It mainly affects fruits like apples and pears.
When Phyllachora pomigena infects fruit, it creates brown or black spots. These spots are usually about 1⁄4 inch (6.4 mm) wide. Sometimes, many spots can grow together and cover the whole fruit. Even though the fruit might look a bit dirty, it is still safe to eat. You can often wipe the sooty blotch right off!

What is Sooty Blotch?
Sooty blotch is a common disease on apples and pears. It makes the fruit look like it's covered in soot or dirt. This "soot" is actually the fungus growing on the fruit's skin. It doesn't usually hurt the inside of the fruit.
How Does Sooty Blotch Develop?
The fungus grows best in certain conditions. It likes cool, rainy weather during the summer. It also thrives in places where air doesn't move well. This often happens in fruit trees that are very dense. Trees that have not been pruned (trimmed) can have poor air circulation. This makes it easier for the fungus to spread.
Why Does it Look Sooty?
The dark spots are made of many tiny fungal threads. These threads grow on the fruit's surface. They form a dark, blotchy layer. This layer looks a lot like soot from a chimney.
Preventing Sooty Blotch
Farmers and gardeners can take steps to prevent this disease. Good air circulation is very important.
Pruning Trees for Health
Trimming fruit trees regularly helps a lot. Pruning removes extra branches. This allows more air and sunlight to reach the fruit. Better air flow helps the fruit dry faster after rain. This makes it harder for the fungus to grow.
Keeping Trees Healthy
Healthy trees are better at fighting off diseases. Making sure trees get enough water and nutrients helps them stay strong. Removing weeds around the base of the tree also helps. Weeds can block air flow and keep moisture trapped.
Is the Fruit Still Good to Eat?
Yes, fruit with sooty blotch is perfectly safe to eat. The fungus only grows on the outside skin. It does not go into the fruit's flesh. You can simply wash or wipe the spots off. Sometimes, a gentle scrub is all it takes.
Cleaning Affected Fruit
To clean fruit with sooty blotch, you can use water. A soft cloth or brush can help remove the spots. This makes the fruit look much better. It will be ready to enjoy!
