Effectiveness of nanoatrazine in post-emergent control of the tolerant weed Digitaria insularis

Journal of Plant Protection Research, 2020
Digitaria insularis (sourgrass) is a monocotyledon weed of difficult control and high invasive behavior. Atrazine is widely applied in the Americas to control weeds in maize culture, but its efficiency against D. insularis is limited. The incorporation

Caracterização anatômica de folha, colmo e rizoma de Digitaria insularis [PDF]

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 plantio direto, onde o herbicida glyphosate vem sendo utilizado repetidamente há vários anos.

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.

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.

Monitoring and baseline of glyphosate-resistant sourgrass in the main soybean growing regions of Brazil

Revista de Ciências Agroveterinárias, 2022
Frequent application of glyphosate for consecutive years has enhanced the selection pressure on sourgrass (Digitaria insularis) populations, which resulted in the development of glyphosate-resistant biotypes.

Trp2027Cys mutation evolves in Digitaria insularis with cross-resistance to ACCase inhibitors

Pesticide Biochemistry and Physiology, 2020
Sourgrass (Digitaria insularis) is one of the most problematic weeds in South America because glyphosate resistance is widespread across most crop production regions. Acetyl coenzyme A carboxylase (ACCase)-inhibiting herbicides have been intensively used to manage D.

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

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.
