Preparation and performance of chlorfenapyr microcapsules with a degradable polylactide-based polyurethane wall material

Abstract

Preparation of chlorfenapyr microcapsules with a degradable polylactide-based polyurethane wall material is described in this paper, the microcapsules improve the utilization rate of chlorfenapyr and are safe for humans and the environment.

Enhanced Insecticidal Activity of Chlorfenapyr against Spodoptera frugiperda by Reshaping the Intestinal Microbial Community and Interfering with the Metabolism of Iron-Based Metal–Organic Frameworks

“…The synthesis of CF@MIL-101-SL was further confirmed by using Fourier transform infrared (FT-IR) spectra, and the results are shown in Figure G. A characteristic absorption peak at approximately 2232 cm –1 was observed in the CF spectra, which was primarily attributed to the stretching vibration of −CN . For MIL-101­(Fe)-NH 2 , the peak at approximately 523 cm –1 was attributed to the stretching vibration of Fe–O, the peak at approximately 768 cm –1 was attributed to the bending vibration of C–H on benzene, the peaks at approximately 1383 and 1576 cm –1 were attributed to the stretching vibration of CO, and the peak at approximately 3429 cm –1 was attributed to the stretching vibration of -NH 2.…”

Mitochondria-targeted nanocarriers doubled the toxicity of oxidative phosphorylation and ATP synthesis disruptive insecticides against Spodoptera frugiperda

“…21 Some researchers have developed functional nanocarriers for Chl to improve its efficiency. 20,22 Smart nanocarrier formulation, which releases Chl in mitochondria, can increase the efficacy of Chl for better S. frugiperda control and reduce undesired side effects. 23…”

“…[17][18][19] For example, chronic exposure to Chl can cause oxidative damage, apoptosis, and immune disorders in zebrafish liver. 13,20 Moreover, cases of dog deaths due to acute Chl toxicity have been reported. 21 Some researchers have developed functional nanocarriers for Chl to improve its efficiency.…”
