Garlic rust caused by Puccinia allii is potentially damaging to garlic crops, has a wide distribution and limits production of the crop in many countries. Different disease management options are being used to reduce its effect. Cultural disease management methods such as rotation with non-host crops, optimum crop density, adequate supply of moisture, use of healthy planting materials and field sanitation with other crops can reduce the intensity of garlic rust by reducing available inoculum to initiate infection.
