Development of Chlorantraniliprole and Lambda Cyhalothrin Double-Loaded Nano-Microcapsules for Synergistical Pest Control

Abstract

Nanotechnology could greatly improve global agricultural food production. Chlorantraniliprole and lambda cyhalothrin double-loaded nano-microcapsules were fabricated to enhance the control of pests by pesticides and improve the pesticide utilization efficiency. The nano-microcapsules were synthesized using a method involving the solid in oil in water encapsulation technique and solvent evaporation. The nano-microcapsules slowly and simultaneously released lambda cyhalothrin and chlorantraniliprole. The cumulative lambda cyhalothrin and chlorantraniliprole release rates at 40 h were 80% and 70%, respectively. Indoor Spodoptera frugiperda control tests indicated that the double-loaded nano-microcapsules were more toxic than lambda cyhalothrin water-dispersible granules, chlorantraniliprole water-dispersible granules, and a mixture of lambda cyhalothrin water-dispersible granules and chlorantraniliprole water-dispersible granules, indicating that the pesticides in the nano-microcapsules synergistically controlled Spodoptera frugiperda. The results indicated that pesticide nano-microcapsules with synergistic effects can be developed that can improve the effective pesticide utilization efficiency and pesticide bioavailability. This is a new idea for achieving environmentally intelligent pesticide delivery.

Facile Synthesis of the Dual Pesticide-Loaded Metal–Organic Framework Hybrid for pH-Responsive Release

“…It is worth mentioning that this hybrid was synthesized by a two-step reaction without organic solvents. Compared to previous dual pesticide-loaded release formulations, − we provided a facile and environmentally friendly strategy in this study.…”

“…Dual pesticide-loaded release formulation is another strategy to reduce the number of pesticides applications and improve their low utilization rate by loading two pesticides simultaneously . However, dual pesticide-loaded formulations often suffer from the use of organic solvents , and complex preparation procedures . Thus, further development of dual pesticide-loaded release formulations demands an improvement in their synthesis procedures and utilization.…”

“…and health pests (mosquitoes, flies, cockroaches, etc. ). − However, pyrethroids have poor water solubility, and their conventional formulations possess high toxicity and low efficiency, hindering their practical application . Therefore, the development of high-efficiency and environmentally friendly pyrethroid formulations is of urgent need.…”

Layered Double Hydroxide Nanosheets Improve the Adhesion of Fungicides to Leaves and the Antifungal Performance

“…Developments in nanotechnology have paved the way for the use of nanocarriers as pesticide release systems. , Various nanomaterials (e.g., carbon nanotubes, graphene oxide, silica nanoparticles, and polymer nanostructures , ) have recently been used as pesticide carriers. Smaller size, large specific surface areas, and good solubility of nanomaterials make them highly applicable for pesticide release systems.…”
