| Abstract: | Objective] To screen out effective biological pesticides against root rot disease on Curcuma wenyujin.Method] We determined the indoor toxicity of seven kinds of biological pesticides against root rot disease on Curcuma wenyujin by mycelium growth rate method.Result] The toxicological tests showed that 0.5％ shiteling amino-oligosaccharin AS and Trichoderma harzianum WP had strong activity against mycelia growth,and their ECs0 values were 1.14 and 3.61 mg/L,respectively.Secondly,3％ Zhongsheng mycin WP,3％ amino-oligosaccharin AS and P.fluorescens WP also had activity against the mycelia growth,and their EC5o values were 11.64,13.52 and 16.61 mg/L,respectively.Con clusion] The 0.5％ shiteling amino-oligosaccharin AS and Trichoderma harzianum WP have good inhibition to the pathogen of root rot,so they can be used in field trials. |
