“…contains mainly 3.5 to 4.0% acetic acid and 80 to 90% water with some strong antifungal compounds such as guaiacol, cresol, 4-ethyl-2-methoxyphenol, and 2, 6-dimethoxyphenol (Yatagai and Unrinin 1989;Ikergami et al 1992;Kim et al 2001). The antifungal compounds such as carboxylic acids and phenols derived from cellulose and lignin, respectively, are considered as volatile organic compounds (Kartal et al 2004;Nakai et al 2007). Thus, it is considered that NVWV was more effective than VWV because the antifungal compounds were vaporized during the preparation process of VWV.…”

“…There is no evidence to support the identification of volatile compounds as polyphenolic compounds, though 2,6-dimethoxy phenol was described as the main component of wood vinegar; this is a volatile substance that could improve resistance of wood against termite and fungi attack (Sameshima et al 2002;Yatagai et al 2002 andKartal et al 2004;Nakai et al 2007).…”

“…Wood tar also has potential as a wood preservative alone or as a component of preservatives [42]. Nakai and co-workers [43] reported that pyrolysis of wood and wood-based wastes is considered to be one of the promising methods of supplying charcoal as solid material and liquids containing a number of valuable chemicals. They attested that some of pyrolysis chemicals may have importance in developing new wood preservatives against fungal degradation.…”

Archeological studies have found that pyrolysis liquids were already used in the time of the Neanderthal. Wood vinegar and other slow pyrolysis liquids are produced as a by-product of charcoal production. However, future business ideas may be the other way round as pyrolysis liquids may replace synthetic chemicals in the form of pesticides and biocides.Directives and regulations related to the sustainable use of pesticides govern and direct plant protection strategies towards a lower use of synthetic chemicals. It is hoped that many mega trends of global policies will boost the use of plant based products given that a reduced reliance on fossil fuel is a general target in the global food and feed production economy. Pyrolysis technology has been actively studied and developed around the world and is linked to the development of the knowledge based bio-economy. The importance and social impact of pyrolysis technologies will also be enhanced because it is a practicable technique in the sustainable use of wastes and biomasses. However, very little scientific evidence is available to support efficacy claims of wood vinegar and toxicology assessments of the products used. Wood tar has been investigated a bit more thoroughly. The aim of this review was to clarify the potential of slow pyrolysis liquids in agricultural use, in particular, in pesticide applications. In addition, some of the main challenges in developing novel bio control technologies are discussed and the barriers in the commercialization of biological control agents are revealed.

“…Scientists in different parts of the world are working for the development and establishment biopesticides or natural pesticides. Biopesticides are natural plant products that have many activities such as insecticidal activity 2,3 , suppress the growth of fungal 4 , repellent to pests 5 , a deterrent to feeding 6 , insect growth regulation, and toxicity to agricultural pests 7 . Wood vinegar which is also called as pyroligneous acid or liquid smoke is a product by processing of high-temperature carbonization of wood with absent of oxygen.…”

Termiticidal activity of wood vinegar from Toona sinensis (TS) sawdust has been evaluated against Coptotermes curvignathus. TS wood vinegar was produced at 250-300°C pyrolysis temperature, and a no-choice test was applied for evaluating termiticidal activity with thirty-three active termites. The concentrations of TS wood vinegar in the dried filter paper was prepared to 0% (solvent only), 2%, 4%, 6%, and 8%. The TS wood vinegar showed strong termiticidal activity and that concentrations of wood vinegar significantly influenced mortality of termite. The termite mortality increased when the concentration of wood vinegar increased, at a concentration of 8% all termites dead after 3 days tested. Forty constituents were characteristic on the basis of GC-MS data, and 33 components were identified. The organic compounds in TS wood vinegar were classified into carboxylic acids, phenols, ketones, amides, aldehydes, furans, esters, alcohols, sugar derivative, and ether, and among of this components, acetic acid comprised 57.43%. The contents of organic fraction of TS wood vinegar and largely acetic acid might be responsible for the termiticidal activity. Base on physicochemical properties, TS wood vinegar has a good quality as well.
