Abstract
The phytotoxic effects of leaves and seeds from Annona squamosa extracts on lettuce ( Lactuca sativa L.) seeds and Mimosa pigra were evaluated. A. squamosa leaf dichloromethane extracts reduced germination and seedling growth of lettuce seeds. In field study, A. squamosa leaf dichloromethane extracts was applied on M . pigra after growing. Fresh weight of M. pigra was decreased with increasing concentrations of leaf dichloromethane extracts. These results suggest that dichloromethane extracts from leaves of A. squamosa may have growth inhibitory substances. Thus, our study indicated that leaf dichloromethane extracts have phytotoxic activity which could be utilized as bioherbicide for future weed control.
