Dise<strong>as</strong>e Identification<br />
Greening<br />
Causal Agent:<br />
Sunlight<br />
Distribution:<br />
Worldwide<br />
Symptoms:<br />
Sunlight causes the formation <strong>of</strong> chlorophyll<br />
in the outer scales which results in<br />
the scales turning green.<br />
Conditions for Dise<strong>as</strong>e Development:<br />
Excessive or late se<strong>as</strong>on nitrogen applications<br />
can delay maturity and enhance the<br />
greening <strong>of</strong> onion bulbs.. Greening can occur<br />
if onion bulbs are exposed to sunlight<br />
during the growing se<strong>as</strong>on or the bulbs are<br />
allowed to cure for extended periods under<br />
moderate light.<br />
Control:<br />
An early fertilization program that<br />
promotes foliar development can reduce<br />
losses from greening at bulb maturity.<br />
Avoid excessive and late se<strong>as</strong>on nitrogen<br />
applications and curing bulbs for extended<br />
periods in the field.<br />
