A fungicide nanodelivery system has been synthesized by the intercalation of dazomet into the interlayer galleries of the zinc/aluminum-layered double hydroxide (Zn/Al-LDH) using the ion-exchanged method. A basal spacing expansion from 8.9 Å in the layered double hydroxide (LDH) to 29.7 Å in the nanocomposite was observed. A Fourier transform infrared (FTIR) study has shown that the absorption bands of the resulting nanocomposite has both dazomet and Zn/Al-LDH characteristics, which confirmed the intercalation of dazomet into the Zn/Al-LDH interlayers with enhanced thermal stability of the guest, dazomet. Further studies on oil palm seedlings were also conducted on the dazomet-intercalated Zn/Al-LDH (DZALDH) and compared with the hexazonazole-intercalated Zn/Al-LDH (HZALDH). Both of them have shown positive effects on oil palm seed growth. This work has shown that the resulting agronanochemicals have a dual-modal fungicide nanodelivery system as a fungicide and a micronutrient supplier to support early plant growth and has the potential to avoid direct contact of fungicides with users due to the intercalation process.

Dazomet-锌/铝双层氢氧化物纳米复合材料的合成及其对油棕种子生长的植物毒性作用

通过离子交换法，通过将达唑麦特嵌入到锌/铝层双氢氧化物（Zn / Al-LDH）的层间画廊中，已合成了杀真菌剂纳米传递系统。观察到基本间距从层状双氢氧化物（LDH）中的8.9Å扩展到纳米复合材料中的29.7Å。傅立叶红外光谱（FTIR）研究表明，所得纳米复合材料的吸收带同时具有苯甲酸酯和Zn / Al-LDH的特征，这证实了苯甲酰胺嵌入Zn / Al-LDH中间层的过程中提高了客体的热稳定性。 ，达索美特。还对插有达唑米特的Zn / Al-LDH（DZALDH）进行了油棕树苗的进一步研究，并将其与六唑唑插入的Zn / Al-LDH（HZALDH）进行了比较。它们对油棕种子的生长均显示出积极的作用。
