It is estimated that worldwide there are around 15,000-20,000 species of orchids with 900 genera (clans) that grow endemic to forests scattered in various countries. Of all orchid species in the world, 5,000 of them are in Indonesia. Broadly speaking, the classification of orchids is divided into 5 subfamilies, 16 tribes (tribes), and 28 subtribes. Phalaenopsis is a genus of orchids which is popular for its diversity and beauty of flowers.

The development of orchid cultivation has never been separated from disease and pest problems. With few disease infections and pest attacks, the beauty will change, of course, the selling price will fall. Orchid plants require extra care to grow with beautiful flowers. Orchid disease can be caused by bacteria, fungi or viruses. Diseases and pests that attack orchid plants can cause death if allowed to continue. Besides that, mishandling can also cause the death of orchids. The purpose of this study was to determine the pests and diseases of the Phalaenopsis amabilis plant.</em></pre><pre><em>This research was conducted on December 2, 2020 and January 13-14, 2021 in Carikan Sukoharjo with 10 samples of Phalaenopsis amabilis plants.
