摘要
[Objectives] This study was conducted to evaluate the toxicity risk of prochloraz-manganese chloride complex to environmental organisms. [Methods] The acute toxicity tests of prochloraz-manganese chloride complex on 8 common environmental organisms, such as Coturnix coturnix japonica, Apis mellifera L., Eisenia foetida, Bombyx mori, Trichogramma japonicum, Brachydanio rerio, Daphnia magna Straus and Scenedesmus obliquus were carried out. [Results] Prochloraz-manganese chloride complex to D. magna EC50(48 h): 1.11 mg a.i./L, with a 95% confidence limit of 1.00-1.26 mg a.i./L; B. rerio LC50(96 h): 2.84 mg a.i./L, with a 95 % Confidence limit of 2.43-3.48 mg a.i./L; S. obliquus ErC50(72 h): 1.88×10-2 mg a.i./L, with a 95% confidence limit of 1.70×10-2-2.16×10-2 mg a.i./L; C. coturnix LD50(168 h): 1.01×103 mg a.i./kg body weight, with a 95% confidence limit of 7.87×102-1.27×103 mg a.i./kg body weight; T. japonicum LR50(24 h): 2.53×10-3 mg a.i./cm2, with a 95% confidence limit of 2.14×10-3-2.99×10-3 mg a.i./cm2; B. mori LC50(96 h): 2.03×102 mg a.i./L, with a 95% confidence limit of 1.79×102-2.30×102 mg a.i./L; A. mellifera(peroral) LD50(48 h)>100 μg a.i./bee; A. mellifera(contact) LD50(48 h)>100 μg a.i./bee; E. foetida LC50(14 d)>1.00×102 mg a.i./kg dry soil. According to the Guidance for Evaluating and Calculating Degradation Kinetics in Environmental Media for Pesticide Registration, prochloraz-manganese chloride complex had low toxicity to A. mellifera, C. coturnix, B. mori and E. foetida, medium toxicity to D. magna and B. rerio, and high toxicity and low risk to S. obliquus and T. japonicum. [Conclusions] This study provides a data basis for the toxicity and environmental safety evaluation of the agent.
