采用气相色谱和高效液相色谱技术,在北方露地和冬春温室条件下分别测定了丙溴磷、甲氰菊酯、吡虫啉、乙酰甲胺磷、啶虫脒、三唑酮在辣椒上的残留消解动态和最终残留量。结果表明,温室条件下丙溴磷、甲氰菊酯、吡虫啉、乙酰甲胺磷、啶虫脒、三唑酮在辣椒上的原始沉积量分别为3.13、1.11、1.23、1.29、1.67、0.38mg·kg-1,分别比露地条件下高74.9%、3.7%、17.1%、27.7%、39.2%、111.1%;施药后1d温室辣椒上的残留量分别为3.78、1.27、1.88、1.36、2.85、0.58mg·kg-1,分别较原始沉积量高20.8%、14.4%、52.8%、5.4%、70.7%、52.6%。丙溴磷、甲氰菊酯、吡虫啉、乙酰甲胺磷、啶虫脒、三唑酮在北方冬春设施辣椒上的原始沉积量明显高于露地条件下的相应值,施药后1d的残留量比原始沉积量明显增加。北方冬春设施辣椒按照推荐剂量使用啶虫脒、三唑酮是安全的,使用甲氰菊酯是不安全的;丙溴磷、乙酰甲胺磷、吡虫啉应严格按照推荐剂量使用。
Gas chromatography and HPLC were used to determine the residues of profenofos, fenpropathrin, imidacloprid, acephate, acetamiprid and triadimefon on pepper in northern open field and winter-spring greenhouse respectively Digestion dynamic and final residue. The results showed that the initial deposition rates of profenofos, fenpropathrin, imidacloprid, acephate, acetamiprid and triadimefon in pepper under greenhouse conditions were 3.13,1.11,1.23,1.29,1.67,0.38mg · Kg-1 respectively, which were 74.9%, 3.7%, 17.1%, 27.7%, 39.2% and 111.1% higher than those in the open field respectively. The residues on greenhouse peppers were 3.78,1.27,1.88,1.36 and 2.85 , 0.58 mg · kg-1, respectively, higher than the original deposition of 20.8%, 14.4%, 52.8%, 5.4%, 70.7%, 52.6%. The initial depositions of profenofos, fenpropathrin, imidacloprid, acephate, acetamiprid and triadimefon on winter and spring peppers in the north were significantly higher than those under the open field conditions. The residue after 1 d The amount of the original deposition increased significantly. Spring and winter facilities in northern winter chili pepper in accordance with the recommended dosage of acetamiprid, triadimefon is safe, the use of fenpropathrin is not safe; profenofos, acephate, imidacloprid should be used in strict accordance with the recommended dose.
