Cypermethrin is a pyrethroid insecticide commonly used to control bagworm infestation in oil palm plantations. It is applied through spraying onto the leaves where the bagworms reside. This article reports the fate of cypermethrin used in a Malaysian oil palm plantation during a typical dry season through the analysis of cypermethrin residue in environmental and palm oil samples collected from a supervised field trial. Residues of cypermethrin were not detected in the soil samples collected at different depths, water samples collected at different points in the experimental plots, and oil samples extracted from fresh fruit bunches (FFB) harvested from each plot for both single and double dosages of treatment throughout the study interval. Analysis of leaf samples, however, revealed that cypermethrin residue was detected for both pesticide treatments up to day 2 after cypermethrin application.

氯氰菊酯在马来西亚油棕种植园中的命运。

氯氰菊酯是一种拟除虫菊酯类杀虫剂，通常用于控制油棕种植园中的bag虫侵扰。通过喷雾将其施用到the虫所在的叶子上。本文通过分析在有监督的现场试验中收集到的环境和棕榈油样品中的氯氰菊酯残留量，来报告在典型干旱季节马来西亚油棕种植园中使用的氯氰菊酯的去向。在整个试验阶段单次和两次剂量处理中，在不同深度采集的土壤样品，在不同样点采集的水样以及从每个样地收获的新鲜水果束（FFB）中提取的油样中未检出氯氰菊酯的残留物。学习间隔。叶片样品分析
