Weeds Control Effect and Residues of Several Herbicides in Tea Gardens
摘要
Abstract
The weeds control effect of several herbicides (glyphosate, glufosinate and combination of glyphosate-acetochlor and glyphosate-auxiliaries) and the herbicides residues in the soil of treated plots in the tea gardens were compared. The results show that the glufosinate had a faster control effect on the weeds. The coverage of weeds decreased to 9.15% on the 7th treatment day. The control efficiency of glufosinate to the Geranium carolinianum L., Sonchus asper (L.) Hill., Conyza canadensis (L.) Cronq.reached more than 95% on the 14th day. Glufosinate showed a faster degradation (the dissipation ratio was 94% on the 30th day) in the soil than the glyphosate (the residue concentration was 0.01 mg·kg-1 on the 58th treatment day). Therefore, glufosinate might be an alternative herbicide for weed control in tea gardens. Acetochlor, as a closed herbicide, had the potential of inhibiting the emergence of gramineous weeds and faster dissipation rate in the soil (the dissipation ratio was 97% on the 21th day), and therefore, it was recommended to control gramineous or the other weeds.关键词
