Studies on Occurrence Pattern of Rough Gentian Leaf Blight and Its Control
摘要
Abstract
Rough gentian leaf blight was caused by Septoria gentianae. Septoria gentianae only infects the leaves of Rough gentian causing leaf blight and heavy losses. The primary infection sources of rough gentian leaf blight were the diseased leaf residue, seed and seedling. The pathogen overwintered mainly al conidia and hypha on the diseased residue in the fields. It was easy to make the disease epidemic in higher temperature, humidity and day-light. Under the natural conditions, the occurrence of epidemics might be divided into five stages. By following methods, Rough gentian leaf blight could be controled effctively by (1) sterilizing seed and seedling with fungicide; (2) rough gentian garden sanitation; (3) sunshading and higher density cultivation and (4) fungicide. The most effective fungicide was Mancozeb.关键词
