Taking‘ Anqiudajiang’ as experimental material，this paper studies the effects of 5
bactericides spread on different ginger growth periods on controlling ginger bacterial wilt. The results indicated
that no remarkable influence on ginger seedling sprouting rate after soaking mother ginger in the bactericides
of Jiangwenjing AS（ astragalus polysaccharide，berberine，alkannin≥2.8%），45% Amobam AS，72%
streptomycin sulfate SP，3% Kejunkang WP，20% Saisentong SC before sowing. It is good for controlling ginger
bacterial wilt after using these 5 bactericides. The control effect of Jiangwenjing AS is the best reaching 92.6%，
and that of 3% Kejunkang WP takes the second place，reaching 90.5%. The income of using Jiangwenjing AS is
the highest，compared with the other treatments. It can reach 350，229 RMB·hm-2.
