Tang, X.F., Jia, J.G., & Wang, H. 1998 [Experiment to control persimmon wooly scale by spraying Sujiek emulsion.]. China Fruits No. 4, 31-32.
Notes: An experiment was carried out in a persimmon plantation in China, seriously damaged by the persimmon wooly scale, Eriococcus kaki. Different concentrations of Sujiek emulsion [of unstated composition] and cypermethrin were applied. Results showed that applying the 1000 or 1500 times solution of 40% Sujiek emulsion to second instars resulted in 100% mortality after spraying. The effectiveness of Sujiek was greater than spraying the 1000 times solution of cypermethrin.
