Investigation on Efficiency of Nanoparticle and Extracts from Plants, and Agricultural Residue for Inhibiting Aspergillus Sp. From Para Rubber In PDA Media

Abstract

The purposes of the investigation on nanoparticle efficiency of extracts from plants, vegetables, herbs and agricultural residue for inhibiting Aspergillus sp. in rubber in ​​Pa Yup Nai Sub-district, Wang Chan District, Rayong Province were to study the efficiency of nanoparticles extracted from plants, vegetables, herbs and agricultural residue for inhibiting Aspergillus sp. in PDA medium. The research was conducted by isolating the fungus in the PDA medium by testing the inhibition zone for 24 and 48 hours of the 10 treatments. Zinc oxide nanoparticles were found to have the highest inhibitory effect on Aspergillus sp., followed by betel nut extracts and the controlled extract which was the least effective. The efficiency decreased as the duration increased from 24 hours to 48 hours. However, the aforementioned test can provide an alternative for rubber cup manufacturers according to their needs and problems.
