CONTROL OF OVERWINTERING STAGES OF MITES ON APPLES USING ETHYLENE DIBROMIDE
Published online by Cambridge University Press: 31 May 2012
Abstract
Overwintering stages of the European red mite, Panonychus ulmi (Koch), and the McDaniel spider mite, Tetranychus mcdanieli McGregor, on harvested apples were destroyed with ethylene dibromide using a dosage of 6 mg/l. for 4 h at 24 °C. Some control was achieved at lower temperatures but the dosage had to be increased accordingly. No injury of the fruit occurred. Taste tests showed that flavour of the apples was not adversely affected even after treatment with 10 mg/l. for 4 h.
