Huang, Z.Y., Chen, S.L., & Lin, Q.Y. 2005 [The experiment of using compound insecticides for Hemiberlesia pitysophila control.]. Journal of Fujian College of Forestry 25(1): 43-46.

Notes: This study was conducted in China to investigate the use of 40% methidathion EC, 40% chlorpyrifos EC, 40% omethoate EC, 95% petroleum oil and 45% malathion EC in controlling Hemiberlesia pitysophila. Results showed that spraying with 40% methidathion EC (1:1000) + 40% chlorpyrifos EC (1:1000) + 40% omethoate EC (1:500) was the most effective treatment. Moreover, compared with using 40% methidathion EC, 40% chlorpyrifos EC and 40% omethoate EC alone, the compound was more effective and reached a control effect of over 90%.
