Use of indicator plants for detection of potato viruses
1989
Jayasinghe, U. | Chuquillanqui, C.
Viruses cause most serious potato diseases, that cannot be controlled by chemical means. Eradication of potato viruses requires complicated procedures that depend on reliable detection methods. One of these methods consists in the use of indicator plants. Potato viruses may also cause disease in plants other than potato (crops, ornamentals and wild species); even plants of other families. Symptoms may be completely different from those produced in potatoes. The property of potato viruses to infect other plants and to produce clear symptoms is used in their detection. This document describes how to grow indicator plants under optimum conditions, free from insects, diseases, and nutrient deficiencies, and how to inoculate and evaluate them
