摘要
Marigold （ Tagetes erecta） originated in South America is the main raw material of lutein, which plays a vital role in treating maeula lutea retinae, im- proving immunity and delaying aging. Black spot is the main disease reducing marigold production. This paper concluded occurrence and damage of black spot, the species and symptoms of pathogens, pathogenic factors, selection of disease-resistant varieties and effective means against black spot, and made a briefly analysis of the existing problems and the corresponding solutions, in order to provide a theoretical basis for disease-resistant breeding of marigold.
