Digitaria insularis Management and Nematode Dynamics in Off-season Maize

Journal of Agricultural Studies, 2020
Maize stands out as one of the most important crops in succession to soybean in tropic countries. However, the susceptibility of both crops to nematodes, can cause a continuous increase in the nematode population, especially in areas where there is the occurrence of weeds susceptible to the parasites.

The population density of Digitaria insularis influences Phaseolus vulgaris agronomic traits

Research, Society and Development, 2022
The common bean (Phaseolus vulgaris L.) is an important species for human nutrition in Brazil and its cultivation has been hampered in recent years by the interference of sourgrass [Digitaria insularis (L.) Mez ex Ekman] populations. However, just a few studies evaluated sourgrass interaction with common beans.

Modelling the Climatic Suitability of Digitaria insularis, a Global Invasive Species, Under Climate Change Scenarios

Weed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Grasses in the Poaceae family are major components of global ecosystems and agricultural systems, and their adaptive success has enabled some species to become highly competitive weeds. Digitaria insularis (sourgrass), a C4 perennial grass native to the Americas and now widely introduced elsewhere, has evolved herbicide resistance and poses an

Effects of glyphosate and clethodim alone and in mixture in sourgrass (Digitaria insularis)

Crop Protection, 2020
Abstract Glyphosate is used frequently in agriculture, and sourgrass (Digitaria insularis (L.) Mez ex Ekman) has become one of the most problematic weeds in Brazil because of its resistance to this herbicide. One of the alternatives for sourgrass control is the use of graminicide alone or in mixture with glyphosate. Thus, this experiment was aimed at

Efficiency of Isolated and Associated Herbicides to Control Glyphosate-Resistant Sourgrass [PDF]

Planta Daninha
: Sourgrass is one of the weeds of great economic importance in Brazil due to its difficulty of control and conditions that allow its emergence and development throughout the year.

Sourgrass Resistance Mechanism to the Herbicide Glyphosate [PDF]

Planta Daninha, 2019
: The knowledge on the mechanism that gives a weed resistance to a particular herbicide is essential regarding scientific, academic, and practical aspects because it determines the recommendations for prevention and management of resistance in the field.

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

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.

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.
