Abstract
The weed seed bank causes damage to agriculture, due to competition with cultivated plants and raising production costs, Cenchrus echinatus has a high seed multiplication and dissemination mechanism and Conyza bonariensis glyphosate resistance mechanism. The objective was to evaluate the potential of Mentha arvensis essential oil by means of fumigation in the weed seed bank. Soil samples (2 kg per treatment) were collected, homogenized and subjected to fumigation for 24 and 48 hours at concentrations of 2.5% and 5.0% of essential oil. The soil was solarized (control) and dried in the shade for three days as a witness. Then, 500 g of soil were distributed in four trays in a completely randomized design, where they received irrigation, identification and registration of emerging seedlings. Data were checked for normality and homogeneity of variance, transformed when necessary and submitted to analysis of variance at a 5% significance level. The averages were performed by Tukey and Dunnet tests at 5% probability. It was concluded that fumigation reduced grass and horseweed emergence regardless of dose and exposure time, with results similar to solarization.
