油橄榄孔雀斑病(Cycloconium olea-ginum Cast.)是我省昆明地区油橄榄树的主要叶部病害,我所自1964年引进油橄榄后随种苗传入此病。目前品种和株数自然感染率为百分之百。多年来虽用过多种化学药剂进行防治,但均未底彻解决问题。至今未能有效地控制该病的蔓延和发展。采用化学防治必须花费较多的劳力和投资,使油橄榄生产成本增加。选育抗病良种已经不是可有可无的事了。
Cycloconium olea-ginum Cast. Is the main leaf disease of the olive tree in Kunming, our province. Since introduced olive oil in 1964, it has been introduced into the disease with the seedling. The current natural rate of varieties and strains of one hundred percent. Although many chemical agents have been used for prevention and control over the years, they have not yet been thoroughly solved. So far it has not been able to effectively control the spread and development of the disease. The use of chemical control must spend more labor and investment, so that olive oil production costs increase. Breeding resistant varieties is no longer an option.
