油橄榄孔雀斑病是油橄榄引种以来发生最严重的一种叶部病害,在昆明、重庆等种植区,引起病株大量落叶、枝枯、树衰,丧失结果能力,尤其卡林品种重度受害,实为油橄榄稳产高产和发展生产的一个突出问题。在开展综合防治研究中,1978—1980年应用生物制剂防治油橄榄孔雀斑病。本文报道自选和引进的生物制剂室内药效测定和林间防治试验的初步结果。试材与方法供试生物制剂有16A-6发酵液(菌号采自广西、西昌一带土壤。从分离放线菌5,000余株中经提纯平板拮抗测定),中国科学院四川分院生物研究所,四川省林业科学研究所和重庆市林业试验场筛选的23—16浓缩液(四川省
Oleifera Penehyriosis is the most serious leaf disease occurred since the introduction of Olea europaea. In Kunming, Chongqing and other planting areas, it caused a large number of diseased plants, such as deciduous foliage, decay of trees and loss of fruition ability, especially heavy damage of Carlin varieties. Olive stable yield for the production and development of a prominent issue. In carrying out comprehensive prevention and treatment research, from 1978 to 1980 the application of biological agents against olive peacock spot. This article reports on the selection and introduction of biological agents indoor efficacy and forest prevention and control preliminary results. The test materials and methods for the test biological agents have 16A-6 fermentation broth (strain No. collected from Guangxi, Xichang area soil from more than 5,000 strains of actinomycetes purified plate antagonistic assay), Institute of Biology Sichuan Academy of Sciences Chinese Academy of Sciences, Sichuan Provincial Forestry Research Institute and Chongqing forestry pilot screening of 23-16 concentrate (Sichuan Province
