Black Spot on Apples; Apple Scab

We all love to eat perfect apples but if you grow apple trees, then watch out for this.


If you’ve ever grown roses you would’ve heard about the fungal disease called black spot that starts of as black blotches on the leaves.

The spots become bigger, in some cases joining up, the leaves turn yellow, and then drop off.

Sound familiar?

Well you’ll be surprised to learn that there is another type of black spot, don’t worry, it’s not on roses, but it appears on apple trees.

In fact this disease is a serious problem for apple orchardists.

Let’s find out more..

Black spot on apples looks different than black spot on roses because there isn’t the typical yellowing of the leaves.

The spots are also more irregular than blackspot on roses.

The problem with this fungal disease is that it also spreads to the apples, especially in humid weather.

Spotting on fruit develops a corky layer which resembles a scab. If this happens on young fruit it can also cause cracking. On mature fruit it's still a problem with the appearance of corky scabs on the surface, affecting the re-sale value.

One thing to note, if your tree has had it in the past, be a good neighbour and spray your plants to prevent further spread because it’s a major problem for orchadists.
