Control Effect Evaluation of 70% Thiamethoxam ZF against Ceratovacuna lanigera Zehntner and Baliathrips serratus Kobus on Sugarcane.

[Objective] The paper was to provide scientific basis for popularization and application of 70% Thiamethoxam ZF. [Method] 70% Thiamethoxam ZF was selected and applied in the soil for controlling Ceratovacuna lanigera Zehntner and Baliathrips serratus Kobus. [Result] 70% Thiamethoxam ZF had good control effect against C. lanigera and B. serratus. The optimum dosage of 70% Thiamethoxam ZF was 450 g/hm²(effective ingredients 315 g). 70% Thiamethoxam ZF (dosage per hm²) mixed with the regular fertilizer (dosage per hm²) should be applied together in sugarcane planting and management from February to June. The control effects against C. lanigera and B. serratus were above 98.4% and 82.9% respectively. The actual yield and sugar content were increased by more than 34 290 kg/hm² and 6.8% respectively compared to blank control. [Conclusion] 70% Thiamethoxam ZF was a new ideal pesticide with characteristics of sustainedrelease, long-lasting and low-toxic for controlling C. lanigera and B. serratus, and should be applied widely in the sugarcane planting area.
