Cai, Z.J., Luo, Y.F., Wen, S.X., Zheng, Y.Q., & Wei, Z.P. 2001 [Comprehensive study on applying Sunspray oil year round to control citrus pests.]. Fujian Journal of Agricultural Science 16(1): 28-32.

Notes: The controlling efficiency of Sunspray 7E and 9E oil emulsion against citrus pests were compared with engine oil emulsion and oxidized dimethoate. The results showed that the controlling efficiency of Sunspray 7E and 9E against female adults of Unaspis yanonensis were 97.4% and 89.6%, respectively, at 10 days after spraying. The efficiency against female adults of Chrysomphalus aonidum was 88.2% and 75.1%, and against Phyllocoptruta oleivora was 97.4% and 95.7%, respectively. After spraying three times with Sunspray 7E and 9E, the population of these pests could be controlled below the economic threshold. In addition, the oils were safe to predatory spiders, parasitic wasps and had no negative effect on orange quality.
