Use of herbicides in the culture of Crotalaria ochroleuca G.Don/Utilização de herbicidas na cultura de Crotalaria ochroleuca G.Don

In areas where crotalaria are implanted, weed species may occur, which require adequate management for their control, as they may be competitive with the crop. In view of the above, this work aims to understand the action of herbicides in the control of the viola string in the crotalaria culture. Th...

Descrição
Resumo:In areas where crotalaria are implanted, weed species may occur, which require adequate management for their control, as they may be competitive with the crop. In view of the above, this work aims to understand the action of herbicides in the control of the viola string in the crotalaria culture. The work was carried out in a greenhouse with a completely randomized design, in a 4x3 factorial scheme, using four herbicides: Sulfentrazone; Flumioxazin; Amicarbazone and Diclosulam, interacting with four concentrations: 25; 50; 75; 100% of the recommended dose plus a control group with no herbicide and with four replications, totaling 52 plots. All herbicides used, even at doses below that recommended by the manufacturer, did not show selectivity to the crotalaria culture. The Diclosulan molecule kept seedlings alive until the seventh day of germination or twelfth day after sowing. With only 68% of the dose of any molecule, it was possible to kill 100% of the crotalaria seedlings.
