Comparative Phytotoxic Effect of the Essential Oil of Chenopodium Ambrosioides and Mentha Longifolia on Avena Fatua
نویسندگان
چکیده
Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was observed in shoot length as compared to root length. Greater Inhibitory effect was observed in M. longifolia oil followed by C. ambrosioides oil. The Essential oil of both the plants caused loss in chlorophyll content and also causes impairment in cellular respiration, thus, affecting the overall physiological growth of test weed. The study concludes that these essential oils has bio-herbicidal property and can be used as environmentally safe bioherbicide.
