Abstract:

Two herbicides, dibut ralin and acetochlor, were studied in this article. Dibutralincould decrease the incidence of soybea n roo t ro t , while aceto chlo r could increase it. Duringthe ea rly period of spraying ( about 10 days ) , some soil fungi ( such as FusariumRhi zoctonia , Pythium, Penicill ium) w ere inhibi ted, but the number o f bacterium increasedlarg ely. Later, dibutralin increased the number of Penicil lium a nd bacterium .Meanw hile, acetochlo r increased the number of Fusarium and Rhi zoctonia , but inhibitedPenicil lium and bacterium .
