In this study, a bio-product of turmeric oleoresin combined with Ag-CS nanoparticles was prepared and evaluated for its antifungal activity Colletotrichum spp. the main causative agent of anthracnose disease in oranges and grapefruits. Technological factors including ingredients, additives, mixing ratios have been calculated and tested to obtain products with the highest durability and dispersion. Experimental results obtained the optimal set of parameters for production at pilot scale of 5 liters/batch with the ratio of active ingredients/additives = 3/1, the optimal temperature for the mixing process is in the range of 40 - 45oC , stirring speed 500 rpm and mixing time 60 min. Conducted evaluation of antifungal activity against Colletotrichum spp. caused anthracnose disease on citrus, the results showed t
