White rust caused by Puccinia horiana is one of the contagious diseases of
chrysanthemum that is able to cause yield losses up to 100%. Chemical synthetic fungicides have been used to
control the disease. Because of harmful effects of the synthetic fungicides, the other alternative measure to control
the disease have to be developed in order to support the sustainable farming system. One of the recommended control measures is the application of biopesticide which is environmentaly friendly.
