Última PHYTOTOXIC POTENTIAL OF Ipomoea batatas EXTRACT , DETECTED THROUGH A NEW TYPE OF SANDWICH MICROBIOASSAY ON THREE SPECIES OF WEEDS Planta Daninha HERNÁNDEZ-ARO,M.; HERNÁNDEZ-PÉREZ,R.; GUADALUPE-TAPIA,G.; GUILLEN-SÁNCHEZ,D.; CASTELLANOS-GONZÁLEZ,L.. ABSTRACT Nowadays, it is very important for researchers to find alternatives that enable the development of a profitable agriculture and a clean environment, therefore, the strategy evaluated in the present study is geared towards the use of the allelopathic effect of many plants. The main objective was to assess the efficiency of a compound derived from extracts of sweet potato (Ipomoea batatas on three weed species under controlled conditions. Different concentrations (1, 5, 10% w/v) were evaluated through a sandwich-type microbioassay in comparison with the traditional Petri dished culture technique. Both tests demonstrated the phytotoxic activity of aqueous extracts of I. batatas, which caused inhibition of germination of A. hybridus, P. oleracea and...

The allelopathic effect studied in many cultures has currently generated great expectations that displayed a natural and environmentally friendly tool for weed management using bioherbicides. The objective of this work was to assess allelopathic influence of residues of S. trilobata on the germination and growth of weeds, as well as their relation with some crops and effects on soil properties. Results show that residues from S. trilobata have inhibited the germination of weeds (31.6 - 72%), increasingly with the applied dose. All residue doses of this specie have inhibited dicotyledonous germination, but only maximum concentration has affected monocotyledons. The residues did not affect onion germination, but stimulated it in radish and tomato, while the...
