Abstract
The ‘Tiepi’ fruit disease is a serious problem in Chinese jujube production in China.
The disease that is very difficult to control, and causes about 30%-80% loss of total yield in many main Chinese jujube producing areas every year.
The toxicity of seven fungicides to two main pathogens (Alternaria alternate (Fr.) Keissler and Phoma destructive Plowr.) of ‘Tiepi’O fruit disease were tested in the house, and the higher toxicity to the two pathogens of fungicides tested in the house were selected to be further tested in the field.
The results showed that the toxicity of carbendazim, mancozeb and difenoconazole were significantly better than others in house test.
The control efficacys of 85% mancozeb, 25% difenoconazole, and mixed spray of 70% mancozeb and 50% carbendazim to the disease in the field were 60.73, 72.70 and 77.08%, respectively.
