Allelochemical of Archidendron jiringa Pods and Sorghum bicolor Biomass Extracts Combined with a Premixed Formulation of Atrazine and Mesotrione

The aim of this research was to evaluate the allelochemicals in jering pods and sorghum biomass extracts combined with premixed formulations herbicides, atrazine mesotrione. conducted laboratory experimental field Department Agronomy, University Bengkulu, Indonesia, from December 2019 July 2020. their combination herbicides were tested on seed germination, weed control corn grown polybags. results showed that aqueous herbicide mixtures mesotrione did not inhibit germination but suppressed length weight radicles plumules. study efficacy weeds (total grasses broadleaves) revealed two agents, when applied separately, by 27 32%, respectively. When combined, increased 56%. Furthermore, plant height, stem diameter, stover treatments. cobs yield per 19 22% separate application found biomass, respectively, 34% herbicides. This provided a novel approach using allelochemical as natural for control.
