California arrowhead is one of the primary weeds infesting paddy rice fields in the Brazilian states of Santa Catarina and Rio Grande do Sul, where the system of pre-germinated seeding is used. The objective of this study was to evaluate the selectivity and effectiveness of saflufenacil application in irrigated rice, either singly or in combination with other herbicides in the same application or sequentially, for the control of Sagittaria montevidensis biotype that is resistant to ALSand PSII-inhibiting herbicides. In the first experiment carried out in a greenhouse, saflufenacil was applied, either singly or in combination with penoxsulam, bispyribac-sodium, pyrazosulfuron-ethyl, bentazon, or propanil to the S. montevidensis (SAGMO 32) biotype and the irrigated rice variety Epagri 108. In the second experiment, single or combined (including sequential) applications of saflufenacil,bentazon, and cyhalofop-butyl were applied to Epagri 108 in open field conditions. Saflufenacil combined with propanil showed a high degree of phytotoxicity and a reduction in the accumulation of dry mass in Epagri 108. Application of saflufenacil, bentazon, and cyhalofop-butyl in combination or sequentially resulted in an increase in phytotoxicity in Epagri 108 compared to when applied singly. A pplication of saflufenacil singly or in combination with penoxsulam, bispyribac-sodium, bentazon, or pyrazosulfuron-ethyl did not adequately control SAGMO 32. |
