    Abstract: Colletotrichum species cause anthracnose in various tropical crops in both cultivation and postharvest periods. The current synthetic fungicides to treat anthracnose sometime show toxic effects for farmers, residues on foods, and environmental impacts. In this work, turmeric extract containing curcuminoids was used as an active ingredient and formulated into a nanoemulsion to control anthracnose in red pepper and tomato fruits. The nanoparticles containing turmeric extract (25 %) were successfully prepared by encapsulation using Tween-80 and PEG 400 as emulsifiers. Out of the three main curcuminoids in the turmeric extract, BDMC was determined as the most abundant constituent via HPLC analysis. Turmeric nanoparticles showed an average particle size of 203 nm, polydispersity index (PI) of 0.322, and zeta potential of -92.7 mV.  In the in vitro antifungal bioassay, this nanoformulation significantly inhibited the mycelial growth of Colletotrichum gloeosporioides and Colletotrichum orbiculare in a dose-dependent manner. Red pepper anthracnose was also consistently suppressed by turmeric nanoparticles but the tomato anthracnose was resistant to this formulation at 10 mg/mL in vivo. The study results proved the effectiveness of turmeric nanoparticles to control red pepper anthracnose in postharvest preservation and suggested developing the innovative nanoformulation as a green fungicide.

    Abstract: Dong Van rock highland - the first international Geopark of Vietnam and geoheritage preservationDong Van Karst Plateau has the richness and diversity in geoheritages. Initial research conducted by Vietnameseand foreign geologists highlighted five types of geological heritages (according to UNESCO classification): type Apalaeogeology, type B- geomorphology, type D- rock, type E-stratigraphy, type I-tectonics. Besides geoheritages, thebiodiversity and the historical, cultural and societal richness of Dong Van Karst Plateau (which met UNESCO criteria of aglobal geopark), has made it recognised as a member of global Geopark Network by UNESCO for the years 2010 - 2014. The management, conservation and rational exploitation of heritages (especially geoheritages) should be raised seriously and given priority in every economic development strategy of the local government, in order to maitain its honourable title and enhance the sustainable socio-economic development. This paper introduce some main features of Dong Van Karst Plateau Geopark, the event of the UNESCO rewarding Dong Van Karst Plateau with the title “Global Geopark” and the issues of preservation of its local geoheritages.
