摘要
研究开发了两种新型稀土配合物杀菌悬浮乳剂,分别是Sm(NO3)3,Nd(NO3)3(B)3。使用差热热重和红外表征了配合物,说明配合物是不同于稀土和小檗碱的一种新物质。对稀土小檗碱配合物乳剂的乳液稳定性、低温稳定性、抗冻性和热贮稳定性等理化性质进行了测定,并考察了其对番茄溃疡病菌、向日葵菌核病菌、尖孢镰刀菌和胡萝卜黑斑病菌抑菌活性。结果表明:两种悬浮乳剂符合国家农药乳剂的标准,且对四种农作物病菌有较好的抑菌效果。
Two new suspension emulsion of rare earths berberine complexes, Gd （ NO3 ）3 （ B ）3, Nd （ NO3 ）3 （B） 3 were studied. The complexes were characterized by infrared spectra and DTA. The results showed that the complexes are new substances different from the rare earth and berberine. Their physical and chemical properties including emulsion stability, low tempera- ture stability, frost resistance and high temperature storage were measured. The antibacterial activity of Clavibacter Michiganensis Subsp, SunFlower Hyphal Cluster Germ, Fusarium Oxysporum and Carrot Peutz Bacteria were also determined. The results showed that the two suspension emulsion were in line with the standard of the national pesticide emulsion, and have a good antibacterial effect on four crops bacteria.
