炔螨特在桑树及土壤中的残留特性
Residue characteristics of propargite in mulberry(Morus alba L.)and soil
摘要
Abstract
In order to guide safe use of pesticides scientifically and make a guideline for using propargite on mulberry safely, the dissipation and final residue characteristics of propargile in different parts of mulberry were explored. The method of liquid chramalography tandem mass spectrometry was conducted to study the residue characteristics in different days after propargite was used and its final residue under different treatments. The results showed that the propargite residue in different parts of mulberry follow the one-order kinetics equations C = Coe -ld. According to the one-order kinetic equations, the half lives of propargite reside in foliage, soii and fruit of mulberry were 6. 78 -10.42, 9.21 - 12.46 and 7. 91 - 10. 85 d, respectively. The final residue study showed that the residues of foliage, fruit and soil of mulberry at 10 days after propargite use were 16.7 % -30.40 % , 29.0% -31.1% and 37.1 % -34.7 % of that at 3 days after use, respectively. The final residues in foliage and fruit of mulberry were both lower than 10.0 mg/kg al 10 days after u-sing propargite. It is recommended that the MRI. in mulberry may be suggested to set at 10.0 mg/kg, the maximum application times were below 2 times and the preharvest interval in mulberry was set at 10 days.关键词
