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

Allelochemical Potential of Alecrim-de-Campinas (Holocalyx balansae Micheli) on Germination and Growth of Species of Agro-Economic Interest [PDF]

Brazilian Archives of Biology and Technology
Herbicides selects resistant weed populations, such as morning glory (Ipomoea triloba L.) and sourgrass (Digitaria insularis (L.) Fedde). Natural compounds represent an alternative control method for weeds.

Biological Cycle of Susceptible and Glyphosate-Resistant Sourgrass Biotypes in Two Growth Periods [PDF]

Planta Daninha, 2018
ABSTRACT: Selecting glyphosate-resistant Digitaria insularis may cause changes in the biological cycle of the species. Therefore, the objective of this study was to evaluate the biological cycle of susceptible and glyphosate-resistant D. insularis biotypes in two growth periods (summer/autumn and autumn/winter). Seeds were collected in the municipality

Growth Analysis of Sourgrass: Does Herbicide Resistance Affect Its Development?

Journal of Agricultural Science, 2019
Sourgrass (Digitaria insularis) is highlighted as one of the most troublesome weeds in Brazilian agriculture. The growth analysis of the species and biotypes with resistance to glyphosate are preponderant to support management strategies. In this way, the aim of this work is to compare the growth of biotypes resistant and susceptible to glyphosate, and

Caracterização anatômica de folha, colmo e rizoma de Digitaria insularis Anatomical characterization of the leaf, stem and rhizome of Digitaria insularis

Planta Daninha, 2008
A anatomia da folha, de colmo e do rizoma de Digitaria insularis foi investigada, visando identificar características que possam estar relacionadas à sua tolerância ao glyphosate. Sementes e rizomas de plantas adultas foram coletadas em campo, em área de

Selection of rhizobacteria for pre-emergence control of wild poinsettia, horseweed and sourgrass

Científica, 2019
This study aimed to select rhizobacteria isolates for pre-emergence control of three glyphosate-resistant species: horseweed (Conyza sumatrensis), sourgrass (Digitaria insularis), and wild poinsettia (Euphorbia heterophylla). Nineteen strains of Bacillus spp. and thirty-four strains of Pseudomonas spp. were isolated from soil samples from the states of
