Control of spot disease of lobular privet
Lobular Ligustrum lucidum belongs to the genus Ligustrum lucidum of Oleaceae. It is an excellent colored shrub and has been widely planted in recent years. However, with the increase of planting area and the growth of planting years, some of its shortcomings are gradually exposed, especially the old seedlings, there are varying degrees of fallen leaves in the rainy season every year, and occur year after year, seriously affecting the landscape effect. It is observed that this situation is caused by the spot disease of Ligustrum lucidum. According to the preliminary observation and study, the pathogen of lobular privet spot disease belongs to semi-known subphylum fungi. Circle
