Abstract Many compounds that are excreted from various parts of plants in the soil show an allelopathic effect upon the germination and growth of many speciesof neighboring weeds in the field. A laboratory experiment has been carried out in order to evaluate the poisonous effect of Senna italica(Mill) Lam Ex Stues in fighting three speciesof weeds. Those three speciesof weeds are as follows: Chenopodium murale L , Echinochola coloumn L and Cyndon dactylon L. The experience treatments upon the air branches extract have the following averages: (0.5%, 1.0%, 2.0%, 4.0%, and distilled water control). Moreover, the effect of the extracts upon the germination of seeds and growth of seedlings has been studied. The air branches extract showed a significant effect with its various concentrations upon lowering the length of the root and the length of the air branches and the dry wet by increasing its concentrations. Furthermore, The treatment of 4.0% has lowered the weed germination by the rate of 24.6% for Chenopodium murale L, 28.1% for Cyndon dactylon L and 33.4% for Echinochola colonum L. Finally, regarding the other growth descriptions, the same treatment of 4.0% with Cyndon dactylon Lshowedthe lowest averages: 6.4 cm of the root length, 11.1 cm. of the feather length and 0.11 mg. of the dry wet.
