THE EFFECTS SOME PLANT (Coridothymus Capitatus L.) RCHB. F. AND Mentha Pulegium L.) EXTRACTS ON THE CONTROL OF AN INVASIVE WEED (Oxalis Pes-Caprae L.)

Abstract

This study was carried out to determine the effect of some plant extracts in the control of weed (Oxalis pes-caprae L.) which is an invasive weed species. The phenolic components of Coridotavmus capitatus (L.) Rchb. F. and the 111. pulegium L. samples UPLC-ESI-MS / MS. determined with the device. In our study, a total of 10 phenolic components were detected in C capitatus and Al pulegium samples. Among the phenolic components obtained from the samples of C. capitatus plant, the most effective components arc; Vanilic acid (2103,24) (mg/kg), Caffeic acid (444,50) (mg/kg), Protocatechuic acid (240,47)(mg/kg) and those of Mi pulegium were Caffeic acid 335,67(mg/kg), Protocatechuic acid 144,73 ( Mg/ kg), 3-4-Dihydoxy benzaldehyde 93.18 (mg /kg) plant. In the experiment, control effects were investigated by applying 3 different doses of C. capitatus and Al pulegium plant extracts applied on germination of stolon tubers of O. pes-caprae, which were placed in petri dishes of 90 X 14 mm. The control effectiveness of plant extracts on the development of root shoots of 0. pes-caprae was statistically determined As a result, it was determined that 20% dose of Al pulegium application was the most effective application that prevented the root development of 0. pes-caprae by 96.53% compared to control petri. The effects of the other application, the dose of 20% C. capitatus, on the root development of 0. pes-caprae were determined that prevented by 98.65%. Control activities of other applications have followed this application.
