Effects of fumigation, cold storage, and fungicide treatment of planting cloves on yield and quality of garlic

摘要

Abstract Fumigation with methyl bromide at 32 g/m3 for 2 h at 21 °C has been recommended for the control of the wheat curl mite (Aceria tulipae) in stored garlic. The effects of fumigation 68 days before planting, of cold storage at 4.5°C for 30 or 60 days before planting, and of fungicide treatment of planting cloves were investigated in healthy mite-free ‘Marlborough White’ garlic planted at Crop Research Division, DSIR, Lincoln, Canterbury on 17 May and 15 June 1983. Fumigation with or without cold storage decreased plant populations, mean bulb weights, and yields, and increased percentages of rough bulbs with side cloves. Cold storage for 60 days with or without fumigation decreased mean bulb weights and yields and increased percentages of rough bulbs with side cloves. The effect of cold storage for 60 days on percentages of rough bulbs was less severe with fijmigation than without. Cold storage for 30 days had smaller effects. There were no phytotoxic or beneficial effects of captan, benomyl, or vinc...
