枸杞是我国名贵药用植物之一,近年来在山东、河北、河南一带大面积发生炭疽病(俗名黑果病),为害严重,常年减产50％左右,严重地区达80％以上,有的生产队甚至毁树不能再种。 当前生产上主要采用药剂防治,大量多次喷施农药,造成农药残留量过多,影响出口,且对人民健康不利。为此,我们在1983—1984两年对这一病害进行了生物防治研究,在山东省庆云县进行田间小区生物防治试验,取得了明显防治效果,找到两种有较好防治效果的菌株。
Chinese wolfberry is one of the precious medicinal plants in our country. In recent years, anthrax (common name black fruit disease) occurs in a large area in Shandong, Hebei and Henan Provinces, causing serious damage. The annual yield is reduced by about 50% and the severe area is more than 80% The team can not even destroy trees. The current production mainly uses chemical control, spraying a large number of pesticides on many occasions, resulting in excessive pesticide residues, affecting exports, and adverse to people’s health. To this end, we conducted a biological control study on this disease in 1983-1984 and carried out experiments on the biological control of field plots in Qingyun County, Shandong Province. Obvious results were obtained and two strains with better control effects were found.
