Study the Inhibitory Activity of Cinnamomum zeylanicum B1. Ethanol Extraction
The article studied inhibition activity of Cinnamomum zeylanicum B1.ethanol extraction against Phytophthora capsici,Fusarium oxysporum f.sp.cubense,Colletotrichum gloeosporioides and Botryodiplodia theobromae by mycelium growth rate method and in viva.The results indicated that Cinnamomum zeylanicum B1 ethanol extraction had good inhibitory activity to Phytophthora capsici.At the concentration of 1.5 mg/mL,the inhibitory rate were 91.94%,EC50 was 0.687 5 mg/mL,63.75% to Colletotrichum gloeosporioides but no inhibitory effect to Botryodiplodia theobromae.The protective efficacy of 20% Cinnamomum zeylanicum ME was 72.79% and 78.91% respectively at the concentration of 100x and 50x.
