Wood fiber biomass pyrolysis solution as a potential tool for plant disease management: A review

Hongyin Zhou et al. Heliyon. .

Abstract

Wood vinegar is a high-value acidic byproduct of biomass pyrolysis used for charcoal production. It is widely used in agriculture and forestry. The adverse effects of synthetic fungicides on the environment and human health have prompted the increasing use of biofungicides as alternatives to traditional products in integrated plant disease management programs. In recent years, there has been an increasing interest in the potential of wood vinegar as a disease management tool in agriculture and forestry. In this paper, the composition and preparation process of wood vinegar and its application in agriculture and forestry were introduced, and the effect and mechanism of wood vinegar against fungi, viruses and bacteria were summarized. The potential of wood vinegar as a sustainable and eco-friendly alternative to conventional chemical fungicides is also discussed. Finally, some suggestions on the application and development of wood vinegar were put forward.

Keywords: Antibacterial mechanism; Disease management; Natural fungicides; Wood vinegar.

Wood vinegar preparation process. Note: The selected biomass raw materials must undergo pre-treatment such as washing, air drying, and crushing to avoid impurities affecting the results, and then enter the pyrolysis reactor for slow pyrolysis (The ratio of water/oil phase in the liquid product obtained by slow pyrolysis is the highest). In this process, the liquid collected by condensation reflux is crude wood vinegar, which contains tar and cannot be used directly. Finally, it can be used after refining.
