ABSTRACT
Aim of the study:
Heavy doses of synthetic weed control chemicals have caused herbicide resistance in weeds. Natural compounds produced by living organisms constitute a wide field for ecologically safe herbicides. The current investigation was directed to test allelopathic potential of hexane extracts of selected plants against common weeds of agriculture.
Material and methods:
Allelopathic potential of Carica papaya, Rhazya stricta, Lantana camara and Pinus roxburghii hexane extracts against weeds viz. Euphorbia helioscopia, Rumex dentatus, Phalaris minor, Avena fatua and Chenopodium album was determined at 100%, 75% and 50% concentration on soil, filter paper and agar. Parameters for assessing allelopathic potential were the germination (%), plumule and radicle size (cm). Data analysis was performed using the software STATISTIX 9.
Results and conclusions:
Based on the findings, it was determined that R. stricta, C. papaya, L. camara and P. roxburghii hexane extract possesses possible suppression effects among which L. camara had the most conspicuous inhibition effects on selected weeds. The inhibitory effects of germination and growth were establishing in order R. stricta > L. camara > C. papaya > P. Roxburghii. Field analysis to assess the phytotoxic ability of these species to be used as herbicide is recommended.
