ABSTRACT

Residue profiling was used to determine the degradation curves of four key insecticides registered for use in US tart cherries. Single and multiple application treatment regimens with minimum and maximum seasonal applications were tested for their effects on residue levels at harvest. The effects of the cherry washing procedure were also tested. The residue profiles suggest that fenpropathrin, cyantraniliprole, phosmet, and spinetoram would be relatively low risk for US tart cherry growers to use when exporting from the US to most prospective international markets. Fenpropathrin exceeded the European Union’s MRL at harvest for single or multiple applications and unwashed or washed treatments, making fenpropathrin a moderate risk for export to the EU.

摘要

残留分析用于确定注册用于美国酸樱桃的四种主要杀虫剂的降解曲线。测试了具有最小和最大季节性施用的单次和多次施用处理方案对收获时残留水平的影响。还测试了樱桃清洗程序的效果。残留情况表明，当从美国出口到大多数潜在的国际市场时，美国酸樱桃种植者使用甲氰菊酯、氰虫苯甲酰胺、亚硫磷和多杀菌素的风险相对较低。甲氰菊酯在收获时单次或多次施用以及未洗涤或洗涤处理超过了欧盟的 MRL，使得甲氰菊酯出口到欧盟的风险适中。
