In this paper, the research team made samples of bio-products (BN) of turmeric resin combined with silver nanoparticles and chitosan and investigated the factors affecting the production of BN preparations. Specifically, the results of research on the production of BN preparations including ingredients, additives, mixing ratios, and technological parameters have been calculated and tested to obtain nano-preparations with durability and dispersion. tallest. Experimental results obtained the optimal set of parameters for production at pilot scale of 5 liters/batch is the ratio of active ingredients/additives = 3/1, the optimal temperature for the mixing process is 40-45 oC, the stirring speed 500 rpm, time 60 minutes. From here, we have successfully fabricated 18 samples of BN1-BN18 preparations with colors ranging from light yellow to dark yellow. Antifungal activity was tested against Colletotrichum spp. causing anthracnose disease and fruit rot disease caused by Phytophtora spp., the results BN1- BN18 products had good antifungal activity, and antifungal activity increased gradually when the content of turmeric oil resin increased.
