Her, and explore the control technique of the main pests. [Method] Investigation of pests and diseases was conducted in main growing base of P. graveolens in Guangxi Province during 2007 -2008, and randomized block design was adopted to conduct field efficacy trials. [-Result] There were 22 kinds of pests and 5 kinds of diseases causing damage on P. graveolens, the occurrence peak of main pest P. litura were in June and September. Field control test showed that 5% hexaflumuron SC and 1% emamectin microcapsule suspension had relatively high control effect on P. litura, the control effect all over 88.58% after spraying for 7 d, and the persistent effect was about 14 d. [ Conclusion] The study would provide useful support for disease and oest control in standardized cultivation of P. oraveolens.展开更多
