Results showed that wood vinegar did not significantly decrease number of thrips when plots were inspected at 60 days after planting. However, number of thrips tended to decrease when wood vinegar was applied at 1:300. In contrast to lower concentrations, number of more thrips was found in plot applied with 1:200. The application of 1:300 wood vinegar slightly decreased infected pods by subterranean ant. The contaminations of A. flavus, A. parasiticus and aflatoxin in peanut seeds at harvest were not significantly affected by wood vinegar application. At harvest, seeds from plants with-or without foliar application of wood vinegar contained high aflatoxin contamination. However, the highest and the lowest aflatoxin contamination were found in seeds from 1:200 and 1:300 treatments, respectively. The responses of Khon Kaen 60-3 from plots with or without fungi inoculation were similar in all traits investigated. The experiment was repeated in the following rainy season in 2005. The experimental design and methods were the same to Experiment 1, except the main plot was variety. Two large-seeded type peanut, Khon Kaen 60-3 and KKU 60 were used. The fungi inoculation was done in all plots. The effect of wood vinegar on the control of thrips and subterranean ant was not evident. However, the thrip populations in all plots were rather low. The contaminations of A. flavus and A. parasiticus in soil were not affected by wood vinegar application. The soil contaminat
ion with fungi was lower at harvest, compared with the contamination in soil before planting. Wood vinegar applied at any concentration significantly decreased the contamination of A. flavus and A. parasiticus in seeds but aflatoxin contamination was not altered as seeds from plants with or without wood vinegar application contained nearly the same level of aflatoxin. The contaminations of A. flavus, A. parasiticus and aflatoxin in seeds were significantly higher in KKU 60 than those of Khon Kaen 60-3. The contamination level was more pronounced when seed storage was prolonged to 1 month under ambient condition.
