Preparation and potential of nanoparticles containing curcuminoids to control fungal diseases in tropical fruits

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