Embodiment 1
[0032] In vitro antibacterial activity test of TIASA5 bacterial strain bacterial agent of the present invention.
Embodiment 2
[0036] Field control test of TIASA5 strain inoculum against kiwifruit bacterial canker.
[0037] At the kiwi fruit experiment station of Northwest Agriculture and Forestry University in Meixian County, Shaanxi Province, the 5-6-year-old "Hayward" variety was selected as the control object.
[0038] On November 5, 2011, the 5-fold dilution of the TIASA5 bacterial strain bacterial agent and the 72% agricultural streptomycin diluted 1000 times and the 46.1% copper hydroxide diluted 1000 times were applied with clear water on November 5, 2011. as comparison. Brush 2 times in a row with an interval of 10 days. The experiment consisted of 12 lesions per treatment, with 3 repetitions. On April 20, 2012 (the peak period of local kiwifruit canker disease), the incidence was investigated, and the diseased plant rate and control effect were calculated.
[0039] Diseased plant rate (%) = diseased plant tree / total number of surveyed plants × 100%
[0040] Control effect (%) = (control ...
