Wild Oat (Avena FatuaL.) and Canary Grass (Phalaris MinorRitz.) Management Through AllelopathyEnvironmental contamination, herbicide resistance development among weeds and health concerns due to over and misuse of synthetic herbicides has led the researchers to focus on alternative weed management strategies. Allelochemicals extracted from various plant species can act as natural weed inhibitors. In this study, allelopathic extracts from four plant species sorghum [Sorghum bicolor(L.) Moench], mulberry (Morus albaL.), barnyard grass [Echinochloa crusgalli(L.) Beauv.], winter cherry [Withania somnifera(L.)] were tested for their potential to inhibit the most problematic wheat (Triticum aestivumL.) weeds wild oat (Avena fatuaL.) and canary grass (Phalaris minorRitz.). Data regarding time to start germination, time to 50% germination, mean germination time, final germination percentage, germination energy, root and shoot length, number of roots, number of leaves, and seedling fresh and dry weight was recorded for both the weeds, which showed that mulberry was the most inhibitory plant species while sorghum showed least allelopathic suppression against wild oat. Mulberry extracts resulted in a complete inhibition of the wild oat germination. The allelopathic potential for different plants against wild oat was in the order: mulberry > winter cherry > barnyard grass > sorghum. Mulberry, barnyard grass and winter cherry extracts resulted in a complete inhibition of canary grass. Sorghum however exhibited least suppressive or in some cases stimulatory effects on canary grass. Plants revealing strong allelopathic potential can be utilized to derive natural herbicides for weed control.

High rate of dependence on medicinal plants for maintenance of health care needs over the decades in communities all over the world especially in Africa and Asia needs adequate scientific verification and authentication. Liver related diseases have however become a global problem. Jaundice was established on 9 of a total population of 12 rabbits of mixed sex, weighing 1.50kg - 2.34kg using an overdose pretreatment of Rifampicin (300mg/ kg bw) P.O. After 3 days, the Animals were administered with various doses of aqueous extract of Azadirachta indica (600, 750, 900mg/kg bw) P.O for each group of rats – A, B, C and D (control ), after which the animals were bled via marginal ear vein at zero hour, 7th and 14th days and the blood used for the following assays: Alkaline Phosphatase, Acid Phosphatase, Total Bilirubin, Conjugated Bilirubin and Alanine Transaminase. Experimental animals exhibited lack of appetite, reduced activity, scratching of the body, emesis, yellow coloration of the sclera, light-colored stool and a little dark urine over time. There was also increase in the levels of the biochemical parameters as the day increased. Aqueous extract of Azadirachta indica (Neem) exhibited increasing elevated levels of Alkaline Phosphatase (ALP), Acid Phosphatase (AP), Total Bilirubin (T/Bil), Conjugated Bilirubin (Conj/Bil), and slightly in Alanine Transaminase (ALT), thus exerted elevated hepatotoxicity on Rifampicin-induced Rabbits. Therefore, the traditional use of Azadirachta indica in management of jaundice should be discontinued.
