Effect of Incandescent and Fluorescence Bulb on Pentachlorophenol and Di-methoate on Spinach Leaf Surface

摘要

Penta-Chloro-Phenol (PCP) is an organ chlorine insecticide while Di-methoate is an organophosphate insecticide used in insect control. This is because of their acute toxicity to insects and short persistence after application. After the pesticide is applied, only 0.1 of it reaches the target site while the rest ends up in environmental contamination 1. Various processes such as absorption, breakdown, transfer and degradation affect pesticides in the environment. Transfer of pesticide refers to moving pesticides away from the targeted sites by leaching, spray drift, volatilization, run off, crop removal and absorption 2.
