Potatoes can be attacked by scab diseases. One is common potato scab which usually occurs on light limy soils and powdery scab which happens on heavy land.

Adding organic material helps both, by acidifying a light limy soil and by opening up heavy ground. Some varieties are more prone, such as Kerr’s Pink, and common scab is worst after a dry summer. But a dry sunny summer is also responsible for the flouriness of the potatoes.
