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 rare earth complex bactericidal suspensions have been developed, which are Sm (NO3) 3 and Nd (NO3) 3 (B) 3 respectively. Thermogravimetry and IR were used to characterize the complex, indicating that the complex is a new substance different from rare earth and berberine. The emulsification stability, low temperature stability, frost resistance and heat storage stability of the rare earth berberine emulsion were studied. The effects of different solvents on the growth of tomato canker, sunflower sclerotinia, Fusarium oxysporum And carrot black spot bacteria antibacterial activity. The results showed that the two kinds of emulsions were in line with the standards of national pesticide emulsions and had good antibacterial activity against four kinds of crop germs.
