Zhang, X.L. 2000 [The extra effective insecticides for control of pomelo scales.]. South China Fruits 29(6): 23.

Notes: Icerya purchasi and circular black scale (Chrysomphalus aonidum) are the two important scales for Guangximiyou pomelo [pummelo] variety and they can badly affect fruit quality. Spraying 200-250 times solution of mechanical oil emulsion + 800-1000 times solution of 40% Supurocide in mid May controlled these scales well. In addition, red mite and rust mite were killed as well. The treatment was effective for 25 days.
