2002年和2003年，进行了细菌菌株Burkholdria OSU 7、芽孢杆菌OSU 142和假单胞菌BA 8对褐腐病（Monilinia拉克萨Ehr.）在杏品种上土耳其马拉蒂亚省的Hacihaliloglu。用1 × 10（6）孢子/ml的M.拉克萨山接种后，每次施用的两棵杏树用三种生物防治剂（Burkholdria gladii OSU 7、枯草芽孢杆菌OSU 142和恶臭假单胞菌BA 8）中的每一种通过在接种的树枝上喷雾（1 × 10（9）cfu/ml）来处理。对未治疗的患者进行了疾病发生率评估。（对照1）和四个不同的治疗组，包括商业疾病管理（对照2，阳性对照：秋季3%波尔多液，粉红色花50%铜，初花期30 g/100 l Corus，末花期300 g/100 l克菌丹）和包括三种细菌菌株的处理（OSU 7，OSU 142和BA 8）。结果表明，阴性对照（对照1）第1年的发病率为9.94%，显著高于商品化处理（2.57%）和细菌处理（2.82-5.00%）。2003年，OSU 7处理的发病率最低（6.80%），而阳性对照和阴性对照的发病率分别为9.45%和28.46%。这一结果表明OSU 7具有作为生物农药有效防治杏褐腐病的潜力。(c)2006爱思唯尔公司All rights reserved.
In 2002 and 2003, a study was conducted to determine the effect of bacterial strains, Burkholdria OSU 7, Bacillus OSU 142, and Pseudomonas BA 8, on biological control of brown rot disease (Monilinia laxa Ehr.) on apricot cv. Hacihaliloglu in Malatya province of Turkey. Apricot orchard at full blooming stage was inoculated with conidial suspension (1 x 10(6) spores/ml) of M. laxa Ehr. After inoculation, two apricot trees for each application were treated with each of the three biological control agents (Burkholdria gladii OSU 7, Bacillus subtilis OSU 142, and Pseudomonas putida BA 8) by spraying (1 x 10(9) cfu/ml) on inoculated branches. Disease incidence was evaluated for untreated (control 1) and four different treatment groups including commercial disease management (control 2, positive control: 3% Bourdox in fall, 50% Cupper at pink flower, 30 g/100 l Corus at first blooming, and 300 g/100 l Captan at last blooming stage) and treatments including each of the three bacterial strains (OSU 7, OSU 142, and BA 8). The results showed that disease incidence for negative control (control 1) was 9.94, which was significantly higher than disease incidence for commercial application (2.57%) or bacterial treatments (2.82-5.00%) in the first year. In 2003, the lowest disease incidence observed in OSU 7 treatment (6.80%), while disease incidence rate for positive control and negative control were 9.45% and 28.46%, respectively. This result may suggest that OSU 7 has potential to be used as biopesticide for effective management of brown rot disease on apricot. (c) 2006 Elsevier Inc. All rights reserved.
