Allelopathic and Antifungal Potential of Lantana camara Root Leachates in Soil

S. Shahid Shaukat and Imran Ali Siddiqui    

Abstract: The allelopathic and antifungal potential of the root leachates of Lantana camara L., a tropical weed was evaluated under glasshouse conditions. Soil drench with full strength concentration caused marked suppression of two root-infecting fungi including Fusarium solani and Rhizoctonia solani. Whereas, a high concentration of the root leachate caused marked inhibition of germination and growth of mungbean, a low concentration (1:2 dilution) enhanced plant growth. When soil was added with urea as an extra source of nitrogen (N) to overcome the phytotoxic symptoms, the toxic effect was not alleviated, suggesting that allelopathic effect due to the root leachate of this weed was not associated with N depletion in the soil. When soil was applied with urea, previously amended with root leachate of L. camara, the efficacy in the control of two soil-borne root-infecting fungi was increased.
