Abstract

<p>Chlorantraniliprole and flubendiamide as novel commercial insecticides could control almost all economically important lepidopteran insects and a number of key pests in vegetables and rice. At present, no researches were focused on the comparative uptake<strong> </strong>of chlorantraniliprole and flubendiamide in protected rice plants. Uptake of chlorantraniliprole or flubendiamide was investigated through hydroponic experiment or foliar absorption experiments. The results indicated that chlorantraniliprole had uptake character in rice plants and could only transport upward in the rice plant while flubendiamide had no uptake character in rice plants.Their uptake characteristic are a factor in determining their actions and toxicology,enrichment parts of the protected rice plants, persistence, metabolic processes and residual dynamics in protected rice plants.</p>

Highlights

  • Chlorantraniliprole and flubendiamide are novel commercial insecticides which can control almost all economically important lepidopteran insects and a number of key coleopteran, dipteran, hemipteran, and isopteran pests in fruits, vegetables and rice (Lahm et al, 2005, 2007, 2009; Hannig et al.,2009)

  • Researches of uptake of chlorantraniliprole in the velvetleaf were reported by Chen (Chen et al, 2013), and no researches were focused on the comparative uptake of chlorantraniliprole and flubendiamide in protected plants such as rice plants

Summary

Introduction

Chlorantraniliprole and flubendiamide are novel commercial insecticides which can control almost all economically important lepidopteran insects and a number of key coleopteran, dipteran, hemipteran, and isopteran pests in fruits, vegetables and rice (Lahm et al, 2005, 2007, 2009; Hannig et al.,2009). The most concerning problem on pesticide preparation was the uptake characteristic of pesticides in protected plants when pesticide preparations were used to control plant insects or diseases. This is a significant factor in determining the actions and toxicology of pesticide, enrichment parts of the protected plants, persistence, metabolic processes and residual dynamics in protected plants. Findings from this study may be used to prioritize chlorantraniliprole and flubendiamide for future evaluations, and to improve understanding of the pesticides utilization efficiency
