If you're a fan of stone fruit, then you might know how delightful apricots are, especially when they're perfectly ripe and juicy. However, what happens when your apricots start to develop a fuzzy layer and smell off? Chances are, your fruit is suffering from rhizopus rot, a fungal infection that affects many types of stone fruit, including apricots.

What is Rhizopus Rot?

Rhizopus rot is a type of soft rot caused by the fungus Rhizopus stolonifer. The fungus is commonly found in soil, decaying plant matter, and even air, making it easy for it to spread to fruits and vegetables. When the spores of the fungus land on the surface of a fruit, they can germinate and penetrate the skin, causing the fruit to rot from the inside out.

The infection typically starts as a small water-soaked spot on the fruit's surface, which then spreads rapidly and eventually covers the entire fruit. The affected fruit becomes soft and mushy and emits a sweet, slightly alcoholic odor.

How Does Rhizopus Rot Affect Apricots?

Apricots are highly susceptible to rhizopus rot, and the infection can quickly spread throughout an entire crop if left unchecked. The fungus thrives in warm and humid conditions, which make apricot orchards a perfect breeding ground for it.

Apricots infected with rhizopus rot will develop a fuzzy layer of white or grayish mold on their surface, which is a telltale sign of the infection. The fruits will also become soft and watery, and their flesh may have a pinkish or reddish tint.
