Efficiency of Wood Vinegar from Coconut Shell to Anti-fungal on Para Rubber Sheet

Abstract

Contamination of fungus on the para rubber sheet affect to the rubber prices lower. Identification of the fungus, the anti-fungal activity of wood vinegar and quantitative analysis of the phenolic compound were used to study of anti-fungal agent in para rubber sheet’s production of the farmers at Ban Phon, Phon subdistrict, Kham Muang district, Kalasin province. By collecting fungus from para rubber sheet, cultivation, purification and identification. Wood vinegars from coconut shell was used for analyze of phenolic compounds and pH values. The wood vinegar from coconut shell in the ratio 1: 100 was used to get rid the fungus on the para rubber sheet. The results showed that there are two kinds of fungi on he para rubber sheet; Penicillium sp., a green fungus and Aspergillus sp., a black fungus. The gallic acid concentration in wood vinegar from coconut shell was 129.72 ppm. Wood vinegar from coconut shell had
effect to a green fungus death average 2.73±0.46 days and a black fungus death average 3.73±0.46 days.
