| ABSTRACT: 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... |

| Abstract: The objective of this work was to evaluate methods of thermal time calculation and the duration of the development stages of lowland rice (Oryza sativa) irrigated by sprinkling. The experiment was conducted during three growing seasons (2010/2011, 2011/2012, and 2014/2015), with five irrigation water depths, six cultivars, and four replicates. Six methods of thermal time calculation were tested: two using the minimum basal temperature; two using the minimum and optimum temperatures; and two using the minimum, optimum, and maximum basal temperatures. For the thermal time calculation, the crop development cycle was divided into the vegetative, reproductive, and grain-filling phases. The methods that used the three cardinal temperatures showed the... |
