沼气发酵残留物已对农田普遍发生的近30种病害具有防治作用，至少有20多种病害的防治效果达到或超过了现行使用的农药效果；在虫害方面，沼气发酵残留物对19种虫害取得明显的防治效果。利用沼气发酵残留物既可防治作物病虫害，而且还起到较好的肥效作用，是发展绿色农业、避免农药污染的理想方法。在抑制病原菌的研究方面，沼气发酵残留物对大肠杆菌、副伤寒杆菌和猪丹毒杆菌等致病菌有显著抑制作用，对十株青霉和曲霉有不同的抑制效果，对17种农作物病原菌有不同程度的抑制作用。长期使用沼气发酵残留物这种“农药”，不会对环境带来污染，也不会产生病虫害的抗性等问题。%MFR has proved prevention and control effects of 30 common crop disases. Compared with the control results with microbicides, the application takes equal or more advantageous effect at least in over 20 crop diseases. As for pests control. MFR shows obvious prevention results in 15 insect pests to 15 crops. The application can also be used in fruit trees, vegetables, cereals and cash crops. Meanwhile satisfactory fertility can be available. It is an ideal approach to sustainable agricultural development and can avoid chemical pollution. According to the researches on pathogens inhibiting, the residues show noticeable inhibitory effect in Escherichia coli, Salmonella trphimurium and others. The antimicrobial effect varies to ten strains of Penicillium and Aspergillus. So is it the case with 17 kinds of crop pathogens.
