Abstract

|
|
|
Putrefactive microorganisms from infected onion bulbs collected at several areas were isolated and identified. The infecting microorganisms were mostly the species of Botrytis, Fusaium, Penicillium, Ericiuia and Pseudomonas, among which the last was not pathogenic to onion bulbs. Fumigation of onion bulbs with Tetrachloroisophthalonitrile cut down decay rate by half of the control and the onion bulbs stored at 80% RH showed slow decay rate than those stored at 90% RH. The decay of onion bulbs was mainly caused by molds and the portions of them were 78-85% of Botrytis, 11-17% of Fusarium and 3-5% of Penicillium.
