- Rust disease on chrysanthemum caused by Puccinia horiana, is a major important disease in Yogyakarta Special Region. The control of rust disease is an uneffective and inefficient method, and so far is still heavily relied on chemicals, whereas until now none of the pesticides listed in the Ministry of Agriculture to control that pathogen is available. The research was conducted by survey and experiments method. Surveys were conducted in the areas of chrysanthemum flower production center in Sleman and Kulon Progo regencies. The survey aims to determine the variation in chrysanthemum rust disease development, in different locations with different soil conditions. Identification and Koch's postulates were done to ensure that P. horiana is the cause of rust diseases. Morphological identification, was conducted using a microscope and a suitable references. Field trials were conducted under plastic house to study the disease progression in various cultivars of chrysanthemum at different sites and different weather
