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.)

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.

Automated summary

This study aimed to determine the control effect of some plant extracts on the invasive weed Oxalis pes-caprae. The results showed that the extracts from C. capitatus and Al pulegium effectively inhibited the root development of the weed. The most effective components in C. capitatus extracts were vanilic acid, caffeic acid, and protocatechuic acid, while in Al pulegium extracts, caffeic acid, protocatechuic acid, and 3-4-dihydroxy benzaldehyde were found to be the most effective components.
