Weed Control of Cuscuta by Silver Nanoparticle Phytosynthesis Extract of Rhazya stricta Plant

The study of Weed control of Cuscuta by silver nanoparticle photosynthesis extract of Rhazya stricta Decne. plant was conducted in two separate experiments as a completely randomized design in three replications in the Medicinal and Ornamental Plants Research Center of Sistan and Balochistan in ۲۰۲۲. The results of synthesizing these nanoparticles showed that the nanoparticles had a maximum absorption at a wavelength of ۴۰۰-۴۱۵ nm, an average size of ۱۰-۱۲ nm, and a spherical and uniform shape. The results of the effects of nanoparticle extracts on the germination and growth of Cuscuta weeds showed that ۱۰۰% silver nanoparticle extract of R. stricta significantly decreased the germination percentage (۵۰.۶۶%), germination vigour (۱۰.۵۰) and germination rate (۲.۰۳) comparison with other treatments. The mean germination time was ۲ days in control and increased to ۴ days after applying ۱۰۰% silver nanoparticle extract of R. stricta. Besides, rootlet length and plantlet length were affected by R. stricta extracts. The most reduction was related to ۱۰۰% silver nanoparticle extract with ۰.۴۰ cm in rootlet length and ۰.۵۰ cm in plantlet length.
