[Pests on zingiberaceous plants and their control in south China]

The pests on the zingiberaceous plants and their occurrence and damage as well as control have been investigated in the ginger plantation of South China Botanical Garden recently. 12 insect pests and 1 mite pest are common. To control them effectively, such as selecting loose, fertile soil as planting field with proper shade, applying healthy and vigorous seeds, seedling and rhizomes for propagation, regulating plant density, sanitizing the field in time are mostly recommended. The application of chemical and biological pesticides and the protection on the beneficial organisms are also stressed.
