Digitaria insularis: cross-resistance between ACCase inhibitors and multiple resistance to glyphosate

Australian Journal of Crop Science, 2023
Sourgrass (Digitaria insularis [L.] Mez ex Ekman) is a problematic weed with special attention to its damage and herbicide resistance in Brazil and Paraguay. Considering the complexity of management and failure in control approaches, the goal of the present study was to monitor and investigate herbicide resistance in D. insularis.

EFFECTS OF ENVIRONMENTAL FACTORS ON SEED GERMINATION AND EMERGENCE OF GLYPHOSATE RESISTANT AND SUSCEPTIBLE SOURGRASS [PDF]

Planta Daninha, 2017
Sourgrass is one of the most problematic weeds of Brazil. It is an aggressive species in the allocation of resources from the environment and reported to be glyphosate resistant in several states of the country.

Digitaria insularis control by using herbicide mixtures application in soybean pre-emergence

Revista Facultad Nacional de Agronomía Medellín, 2021
Sourgrass (Digitaria insularis) is one of the main weeds in the soybean crop. In order to control its growth, an increase of herbicide rates is required to simplify its management as it a plant with high vegetative capacity and seed production. It implies to select the herbicide-resistent Digitaria insularis biotypes.

Doubled density and increased resilience: Consequences of seven consecutive annual dry‐season fires to the unburned Cerrado grass layer

Journal of Applied Ecology, Volume 62, Issue 12, Page 3436-3455, December 2025.
The Cerrado grass layer benefits from frequent fires and is resilient even to an extreme fire regime, such as seven annual burns. Recurrent mid‐dry‐season fires are not harmful to the grass layer and should be less concerning than prolonged fire‐suppression regimes, which diminish grasses' biomass, cover, diversity and functioning. Maintaining frequent

ALLELOPATHIC EFFECT OF Sorghum bicolor AND Digitaria insularis ON GERMINATION AND INITIAL DEVELOPMENT OF CANOLA

Revista de Agricultura Neotropical, 2020
Agriculture depends on biotic and abiotic factors, and one of them is allelopathy, defined as the chemical interference that one plant has on others, which can negatively affect germination.

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Glyphosate-Resistant Sourgrass Management Programs Associating Mowing and Herbicides [PDF]

Planta Daninha
: Currently, sourgrass is one of the most important weeds in grain production areas in Brazil. The objective of this work was to evaluate the efficiency of associated systems composed by mowing and chemical control against clumped sourgrass. In the first

Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating
