Abstract
The phenomenon of vegetative and floral malformation in old mango trees as well as in mango seedlings is now common in Egypt. Ob­vious relationship between mango malformation and the mango bud mite, Aceria mangiferae and the fungus Fusarium moniliforme was record­ed. The aim of this work is to produce mango seedlings free from these pests by using mango twigs fumigated with methyl bromide under differ­ent conditions. The results revealed that the maximum mortality (100%) of mango bud mite could be obtained by fumigation with methyl bromide for 24h at the concentrations 12.9 , 9.0 and 7.0 mg / I under the con­trolled temperatures 10, 20 and 30°C , respectively. If the period in­creased to 48 h, the concentration would be 10.3 , 7.7 and 7.7 mg/I at the previous temperatures , respectively . Maximum mortality (100%) after 24h exposure for the fungus was obtained with the concentrations 77.4 , 71.0 and 58.1 mg/I at the temperatures 10,20 and 30 °C , re­spectively. If this period increased to 48 h, the respective concentrations would be 71.0 , 64.6 and 51.6 mg/I.
