The main diseases and pests of pomegranate in Huaiyuan area and their control.
Investigation over 4 years revealed that there were more than 20 important pests and diseases in this pomegranate producing area in Anhui, China. Insect pests included aphids, scales (cottony cushion scale [Icerya purchasi] , mulberry white scale [Pseudaulacaspis pentagona] and hard wax scale), yellow peach grub (Dichocrocis punctiferalis [Conogethes punctiferalis]) and peach fruit moth (Carposina niponensis). Trunk canker and leaf spot diseases also occurred. Chemical control played an important role. Hard wax scale was controlled by spraying of 20% fenvalerate (solution of 1200) in late June-early July. Peach fruit moth was controlled by ground spraying 50% phoxim (solution of 500) when overwintering larvae occurred. Trunk canker was controlled by spraying 70% barium polysulfide (solution of 20-30) to the trunk and branches.
