The development of medicinal plant extracts to control Weed germination and growth

Abstract

Study on the inhibition of germination and growth of weeds in rice fields. The extract from the leaves of Xy/ocorpus gongeticus Parkins and Porinori onomense Hance using fermentation Maceration and extraction techniques for Sequential Extraction with three types of solvent hexane, ethyl acetate and methanol. The resuLts showed that Leaf extract of Xy/ocorpus gongeticus Parkins with ethylacetate at a concentration of 2,000 -3,000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of Fl is the highest. Leaf extract of Porinori onomense Hance with hexane at a concentration of 2,000 3,000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of F4 is the highest. Which can be used for research and development of natural products from plants to control weeds in rice fields to develop further research to commercialization
