The symptoms; appear as orange pustules on the leaves, which render the chive crop useless.
The leaves turn yellow,and the chives wither and die prematurely, whereas with onions and garlic, the infection is only likely to reduce the bulb size.
Later in the season the orange spores turn black, and these survive through the winter months.
No fungicides are currently available to amateur gardeners to control this problem.
To control the outbreak, promptly remove and destroy all infected plants.
Because the surrounding soil may contain resting spores do not plant plants of the allium family in this area for two or three years.
